Stop randomly and graphic glitch

Hi all

Last week a few my mac began random switching of. When I turn back on (or anytime I turn on) it shows glitchy graphics on the scree of apple. Horizontal lines and the Apple logo appears fractured. After the loading half bar fills, that he goes to a gray screen and custom move forward, usually ends up turn. If I go to restart it, eventually, it will start up.

info on Mac:

Later 2011 15 inch macbook pro

I7 to 2.2 ghz

RAM 16 GB (updated 6/7 months ago)

OSX:10.11.2

Example of graphical glitch.

I ran the Apple Hardware Test, which found nothing wrong: using Apple Hardware Test - Apple Support

The first time that has happened, that I was running two virtual machines and the Mac started running very hot.

Any help would be appreciated

Thank you.

This is a known issue, see the link below:

    Hello

    Just a question: are you an authorized service provider?
    I ask this question because it looks like you are an ASP because you have so many laptops and you have tested different things.

    It's really hard to say what the reason is for this but I think that in this case, you should contact Toshiba directly. Maybe it s a known issue and it can be fixed in a few minutes.
    So ask for it and wait for a response.

  • Win 7, games and graphics glitches/display driver stops resonding

    It is essentially, while the game (WoW or Borderlands in my case) there will be a variety of glitches that occur. I know not just the terms for each of them, but it's going is going to be whatever it is grids of colored seemingly random pixels (pink and green often enough) polygons is extended into madness and whatnot, often accompanied by the "display driver xxx has stopped working...» "(yes I see it a lot and still do not remember the exact wording: /). Pixel an individual will persist even after everything is closed and I'm back on the desktop. In addition, these do not occur immediately and I have no real way to predict when it will happen across that anywhere from 5 minutes to... hours for the first time and the computer seems to be more sensitive then to the point where I'm going to try to play WoW and have the message "display driver has stopped working etc." appears once every 10-15 seconds. Now it's all when I put in very low or setting graphics parameters as low as possible. If I change to something more moderate or what I * think * my computer must be able to manage, I run the risk of having a blue screen.

    OS: Win 7 64 bit (says build 7600)
    Processor: Intel Core 2 Duo E8500 3.16 GHz 2.83 Ghz (copied from my system page)
    Graphics card: Nvidia GeForce 9800 GT

    The drivers are all to date and stuff overheating is certainly not a problem (map revolves around 52C - 56 c, lower when there is no game product). I thought it was a heat issue at the time where I got it and my dressing at the time (who curiously seems to have worked until recently) has been to increase the speed of the fan and run graphics with minimal adjustments. I checked my memory sticks, and those who seem to be good as well... both of things I tried to figure out/deal with that there is probably another thing I checked and I do not forget to mention. Any idea or ideas would be wonderful.

    Try reducing harware acceleration.

    1. open the screen resolution by clicking on the Start button, Control Panel, and then, under appearance and personalization, click on adjust the screen resolution.

    Hello

    You really need to contact the seller and the manufacturer of system support. In OEM for system
    Maker is responsible for the functioning Windows and hardware. So no matter
    of cause, it is to solve. And it is under full warranty and may need repair or replacement.
    Keep in mind do you more they will say that it is something you have done. Added as
    even if you are somehow able to solve the problem you would still want it documented just in case where
    There are other related issues on the road.

    BCCode: 0x0000007f with the parameter 00000008 7f usually means a hardware problem.

    Have you added a hardware or drivers updated recently? Check Control Panel - Windows
    Updates to see if all drivers have been updated it just before what is going on has begun.

    For 7f - this could be a problem of material such as uncomfortable cards or memory, although it
    are other causes. Power electric low could also lead to this. Use the above troubleshooting utilities
    and below and when you get to the drivers and segments of memory see below then
    go back troubleshooting if necessary.

    If a PC remove ALL power. Opening the case, remove and reinstall all memory cards and ALL
    cable (try not just to close) on both ends if they are accessible and on the device ends if
    No (remove the cables and the relocation of their aid to eliminate minor corrosion). On a laptop
    on everything that can be done is to reinstall the memory.

    Notice the 08 (double fault) as 1st parameter means there are likely two causes. Do not forget
    to update your drivers manually by using Windows updates only detects certified pilots and
    Microsoft and the manufacturers are far behind in this process. Update the BIOS of the card NETWORK, WiFi, and
    Display/video and other important factors.

    If a laptop or a PC, you will need to take a shop (not BestBuy or other BigBox stores) or

    BCCode: 7F 0x0000007F which is the same as 0x1000007F

    UNEXPECTED_KERNEL_MODE_TRAP bug control has a value of 0x0000007F. This bug check indicates that the Intel CPU generated a trap and the kernel could not catch this trap.

    This trap might be a bound trap (a trap the kernel is not allowed to capture) or a double foul (an error occurred during the processing of an earlier fault, which always results in a failure of the system).

    Important info if you received a STOP Code

    If you received a blue error screen, or a stop code, the computer stopped abruptly to protect against data loss. A hardware device, its driver or software might have caused this error. If your copy of Windows is shipped with your computer, contact your computer manufacturer. If you purchased Windows separately from your computer, Microsoft provides support. To find contact information for Microsoft or the manufacturer of your computer, Contact Support.

    If you have experience with computers and try to recover from this error, follow the steps in the Microsoft article solution STOP (blue screen) errors in Windows.

    These actions could prevent a mistake like this does not happen:

    1. Download and install updates for your computer from Windows Update device drivers.
    2. Scan your computer for computer viruses.
    3. Check your hard drive for errors.

    UNEXPECTED_KERNEL_MODE_TRAP parameters

    The first parameter that is displayed on the blue screen indicates the number of trap.

    The most common trap codes are the following:

    • 0x00000000 or division by zero error, indicates that a DIV instruction is executed and the divisor is zero. Memory corruption, other hardware problems or software failures can cause this error.

    • 0 x 00000004, or overflow, occurs when the processor executes a call to an interrupt handler when the overflow (OF) is flag set.

  • 0x00000005, or limits check fault, indicates that the processor, then executing a BOUND instruction, determines that the operand exceeds the specified limits. A BOUND instruction ensures that a signed array index is within a certain range.

  • 0 x 00000006 or Opcode not valid, indicates that the processor attempts to execute an invalid instruction. This error occurs generally when the instruction pointer is corrupted and point to the wrong address. The most common cause of this error is hardware memory corruption.

  • 0x00000008 or Double fault, indicates that an exception occurs during a call to the previous exception handler. In general, two exceptions are handled in series. However, there are several exceptions that cannot be handled serially, and in this case, the processor signals a double fault. There are two common causes of a double fault:
    • A kernel stack overflow. This overrun occurs when a cover page is hit, and the kernel tries to push a frame. Because there is no battery left, a stack overflow results, causing the double fault. If you think that this presentation has taken place, use ! thread to determine the limits of the stack, and then use KB (display Stack Backtrace) with an important parameter (for example, 100 KB) to display the full stack.
    • A hardware problem.
  • Less common trap codes are:

    • 0x00000001 - a system call - debugger

    • 0 x 00000003 - a breakpoint in the debugger

    • 0 x 00000007 - a statement of material with no present coprocessor coprocessor

    • 0x0000000A - has corrupted Task State Segment

    • 0x0000000B - access to a memory segment that was not present

    • 0x0000000C - access to memory beyond the limits of a stack

    • 0x0000000D - an exception not covered by another exception; a protection fault concerning violations of access to applications

    For other numbers of trap, see an Intel architecture manual.

    Cause

    0x7F bug check occurs after the installation of a faulty or incompatible hardware (including memory) or if installed hardware fails.

    A double fault can occur when the kernel stack overflows. This overflow occurs if multiple drivers are attached to the same battery. For example, if two file system filter drivers are associated to the same stack and then again the recursively of file system, the capacity of the battery.

    Resolution

    Debugging: Always start by the ! analyze extension.

    If this extension is not sufficient, use the debugger kv (display Stack Trace) command.

    After using one of these commands, reuse kv to display the new battery.

    Troubleshooting: If you have recently added the material to the computer, remove to see if the error recurs. If the hardware failure existing, remove or replace the faulty component. Run the diagnostics of material that does not have the system manufacturer supplies to determine which hardware component.

    The scanner memory is particularly important. Faulty or incompatible memory can cause this bug check. For more information on these procedures, see the manual of your computer. Check that all the cards in the computer are well calibrated. Use an ink eraser or electrical contact treatment, available in electronic supply stores, to ensure the adapter card contacts are clean.

    If the error appears on a newly installed system, check the availability of updates for BIOS, SCSI, or card network controller. These updates are generally available on the Web site or the hardware manufacturer BBS.

    Check that all hard disks, controllers, hard drive and the SCSI adapters are compatible with the installed version of Windows. For example, you can get information about compatibility with Windows 7 in the Windows 7 Compatibility Center.

    If the error occurred after the installation of a new or updated device driver, you should remove or replace the driver. If, in this circumstance, the error occurs during the startup sequence and the system partition is formatted with NTFS, you may be able to use Safe Mode to rename or to delete the faulty driver. If the driver is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console in order to access the file.

    Also to restart your computer and press F8 to character-based menu that displays the choice of operating system. In the menu of Advanced Options , select the last known good Configuration option. This option is most effective when you add a single driver or service at a time.

    Overclocking (setting of the CPU to run at a speed higher than the nominal specification) can cause this error. If you have overclocked to the computer that is experiencing the error, return the CPU to default clock speed setting.

    Check the system log in Event Viewer for additional error messages that might help identify the device or driver that generated the error. You can also disable caching memory BIOS to try to resolve the problem.

    If you have encountered this error during the upgrade to a new version of the Windows operating system, the error can be caused by a device driver, system service, an anti-virus or a backup tool that is not compatible with the new version. If possible, remove all third-party device drivers and system services and disable all antivirus before upgrade you. Contact the software manufacturer for updates of these tools. Also, make sure that you have installed the latest Windows Service Pack.

    Finally, if all of the steps above do not resolve the error, take the system motherboard to a repair for the diagnostic facility. A crack, a scratched trace, or a defective component on the motherboard can also cause this error.

    ===========================================================

    It's my generic how updates of appropriate driver: (updating the video/display driver and BIOS)

    This utility, it is easy see which versions are loaded: run DriverView - set the VIEW to hide
    Microsoft drivers - update those without drain in their names (and BIOS and chipset).

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now click on
    Driver update (this can do nothing as MS is far behind the certification of drivers) - then right
    Click on - uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  • Music guard play/pause randomly and keep Siri activation with Apple earbuds in

    So about a month ago I bought a pair of new headphones from Apple at the Apple Store, they worked very well until last week, they kept turning on my music and stop randomly and activation of Siri. First is was not often, but now if that happens constantly, and it's really got on my nerves. I was looking through all the discussions, but they have had the problem with the Apple earbuds No. This is never happen to me before with the other Apple hear buds I've owned. I think I might have just gotten a lemon but I really want to go buy another pair.

    Accessories Apple are guaranteed for one year from their date of purchase, even if purchased separately from the iPhone, which in this case, they follow the warranty period of the iPhone. Feel free to contact Apple for support and service - Apple supported. You can either an appointment at the Genius Bar on your headphones or have them be replaced by express delivery by putting in place the replacement telephone. It seems as if the remote party on your helmet is somehow physically stuck inside that controls everything you described and it continues only when the headphones are connected. They will be able to set you up with a replacement, free of any cost to you as long as your helmet were not thrown or clearly abused.

  • HP Pavilion Slimline s5304y strange behavior and stops randomly

    To start, here is my card:

    HP Pavilion Slimline s5304y

    Windows 7 Home Premium 64 - bit SP1 Build 7601

    AMD Athlon II X processor 2 215

    4 GB of RAM, blah blah blah

    Here are the symptoms:

    -Win7 starts to act strangely, when the keys are depressed they'll keep recording (like that, but forever)

    -Then it will attempt to force the closure but I keep open Word 2007, which will block the closure and I gives me the option to cancel or to force stop word.

    -J' I usually Cancel to see what it does, sometimes it continues to operate normally, sometimes, attempts to stop become more frequent until it ask no more, and Word cannot veto the shutdown request.

    -When I look at the Event Viewer system, he says he is told what USER (me) has launched the stop, as if it were normal.

    -A little more digging in the event viewer application section says that before stopping, "HP Support Assistant Service" had a "PowerEvent handled successfully by the service" with EventRecordID of 10883.

    -Meet system Event ID 109

    There is no indication that something went WRONG minidump, no discharges of any sort, sfc/scannow ran own just like chkdsk, memtest, tester of windows 7 and all other diagnostic tools.

    He did it before, but very rarely, so I thought nothing of it (which happened in the spans of the months apart) but now happened several times a day.

    Recent software additions:

    Installing the software and drivers Lexmark Prospect Pro205

    -Updated Nvidia graphics drivers Geforce 6150SE nForce 430 to 8.17.12.9573 and it's Helper service ver 295,73

    What I did to try to rectify the situation:

    -Scanned with each virus/malware free scan in existence - deleted an infected file from Java Java/CVE-2011-3544. O operate. And another unrelated to the advertising program.

    -Updated HP Assistant and Advisor

    -Updated several times with various updates for windows 7

    -Clean the case thought it was overheating, but nope - clean as a whistle, normal running time

    -Good fans checked

    -Extract from food - looked good, constant voltage

    I haven't checked the power extension cables. I heard there is a problem with shorting out on the 24-pin extensions, but I didn't have an extension of 24 pins on the power cables.

    I've heard others have had problems with HP stopping randomly with a strange behavior, so I wanted to see what you guys have to say.

    Could this be problems of power with my house? The wiring is old... Or more likely is a short circuit in the cable/PSU?

    How can I easily repair/test of this theory?

    -All right, so the system restore has nothing but destroy some files, because I couldn't not correctly backup the drive between the random stops.

    However, I found the solution to my problem, that you won't believe.

    Short answer: I replaced the stock HP keyboard (model KU-0841) who seems to have been short.

    The long answer:

    -When the computer kept shutting down even in safe mode after a destructive recovery, I started watching again material.

    -Noticed my typing would sometimes record, sometimes just go crazzzzzzzzzzzzzzzzzzzzzzzzzzzy (like this).

    -Then comes the keyboard no longer works. Thus, while the veto stops with WORD 2007 and using the keyboard on the screen in Win7, I thought it was a terrible virus - it wasn't.

    -When I unplugged the USB keyboard it's a strange electric 'bzz' sound, like what you hear when static is unloaded. It turns out that the USB port has been be short-circuited by the keyboard.

    On the keyboard and the USB plug was going well, so I don't know who is to blame again, however - if someone is having the same weird problems with events of the power of the nucleus and 1074 with 0x500ff errors-try to check your hardware.

  • HP ENVY 15 Notebook PC: Intel HD 4600 graphics driver has stopped responding and recovered after upgrade Windows 10 1511

    16/11/2015 Microsoft installed automatically 'upgrade of 1511' on my Windows laptop, 10.

    (This laptop has been previously successfully upgraded to window 8.1 for Windows 10 in August.)

    After the upgrade of 1511, I started to receive the following error while playing at Microsoft games:

    "Display driver stopped responding and has recovered - Display driver Intel HD Graphics driver for Windows 8 (R) stopped responding and has recovered."

    According to Device Manager, installed upgrading driver 10.18.15.4256 dated dated 15/07/2015.  I did a restore to 10.18.15.4248 as dated 29/06/2015.  This has not solved the problem.

    I checked HP Support Assistant and apply labeled sp72370 10.18.15.4248 Rev c dated 05/08/2015.  This has not solved the problem.

    I am committed service HP Smart friend and they are reapplied 10.18.15.4248 via Device Manager web search pilot.  It has installed Intel Driver Update Utility 2.2, but the newer driver has not been installed because of "driver installed by manfacturer (HP).

    HP support person recommended restore new to restore point before Microsoft «upgrade» 1511   I was not comfortable doing so, as 'upgrade' was an important update from Microsoft by using the same process as the initial migration of Windows 8.1 to Windows 10.  The customer can no longer control the timing of updates and upgrades are cumulative - is no longer able to choose specific updates.

    For now I'm wrong to live with this error condition, as seems to have an impact on games and not other normal operations.  My laptop there one provided by HP NVIDIA Geforce GT 740 M, which is Windows compliant 10 and seems to operate normally.  Some of my apps choose the Intel driver, and others choose the NVIDIA driver.  I don't know how applications choose which one to use.

    What a problem like this to be resolved when Microsoft control completely the update mechanism and HP doesn't seem to update drivers available via the HP Support on a basis common?

    I've disabled the Intel HD graphics driver and used the NVIDIA graphics driver for the game.  No problem.

    Disabling the driver Intel resulted in the reving fan at a higher speed intermittently.

    Support for HP Smart friend assured me that the behavior of higher fan speed would not result in problems with premature failure on the road.  You agree?

    They said that my choice was to keep the disabled Intel HD graphics driver and use the NVIDIA only, or living the problem until HP one releases pilot newest Intel - it affects only game, all other functions seem normal.

  • WOW/graphics error "display driver nvlddmkm stopped responding and was retrieved successfully."

    Help, please. On the next computer I have terrible crash problems while playing WoW. Critical error WOW States: "not enough memory to process command - 11 538 bytes requested."

    When running 3D Mark Vantage I can reproduce the "display driver nvlddmkm stopped responding and was recovered successfully.

    Processor Intel Core i7 CPU 920 @ 2.67GHz
    Details of the component
    NVIDIA GeForce GTX 295 graphics
    4 095 MB total graphics memory available graphic set
    Main hard drive 53GB free (140 GB Total)
    64 bit version with service PAC 2 Vista Ultamate

    Forums are full of posters indicating that it is a Vista / Nvidea incompatibility problem that has been around for years and that the problem is not treated. I tried everything I can think of, check the RAM to download new drivers, to the removal of unnecessary records of WOW. I reinstalled everything, run each diagnostic tool in the plane, patches downloaded, checked for the virus and still no help.

    I am currently able to play WOW on the smaller graphics settings and avoid cities. With this level of equipment, it's a shame, really, I should be able to do more.

    Did anyone have any suggestions of what I can do at this point?

    OK, I did a lot of research on this issue.  The problem lies in the Blizzard, most of the time.

    World of Warcraft is a set of 32 bits.  Because it is strictly 32 bit, it only has access to 2 gigabytes of memory.  Windows manages the other 2 giga of addressable space.

    Most of the developers of games flag their games before the compile time to use larger amounts of memory.  Blizzard doesn't do this, because their anti-cheat system and third-party tools rely on the 32-bit addressing and address 64-bit would mean that they must all be rewritten.

    What happens in the game, is that your footprint large capacity memory card is mapped in the game.  In general, it is when your settings are high, because it uses the most memory, which explains why the game is playable when you use minimal settings.  Given that the configuration of your particular graphics card uses close to 2 gig of RAM itself, quickly force you the game short of memory addressable space.

    To resolve this problem, you may be able to play with reduced settings.  Reduce your resolution is usually the best way to limit the use of memory, since it increases exponential use RAM when you increase the resolution.  You might have to play with different parameters.  You can open the upward Task Manager and monitor the use of your memory WoW game to see where the sweet spot is maintaining your memory under control.

    Blizzard will have to make the difficult choice to eventually allow access extended memory.  More people are buying equipment like yours, this problem will be more widespread.

  • Gmail button (in internet explorer) keeps having moved to the right in my taskbar when I wasn't staying on the left (that's why I first open). How can I get the taskbar buttons to stop randomly to reorganize and stay in order?

    Gmail button (in internet explorer) keeps having moved to the right in my taskbar when I want to keep it on the left (that's why I first open).  How can I get the taskbar buttons to stop randomly to reorganize and stay in order?  I'm talking about the buttons on list of my open applications and documents in Windows Vista.  The bar tasks are "locked", but the button of the window open with gmail in internet explore reappears suddenly in the good moments apparently random.

    It is in the middle part of the taskbar (what I found online so far is on the start menu, the quick launch area or area/system tray of notification, the location of the taskbar in full, either about grouping taskbar - I disabled because I would like to separate).  Can anyone help?  I don't understand why this is happening (or why microsoft would never do).

    Lock the taskbar that it prevents to be moved elsewhere on the office and maintains the different sections where they are - it does not block the tabs showing what is open where they were when they were opened.  There is no control for this function.  Maybe if you uncheck similar taskbar buttons group it will help, but I honestly don't know (and fear he won't make any difference - it may even make things worse).  This also happens to me and I was unable to find an answer.  I think that there are more than just random, but I can't telll you why he moves the legs periodically (sometimes it works fine all day and other days it happens almost immediately).  But still, there is no control for this function, so there is no way to tell him to keep a specific order or to lock an established order, once it has been created.  I suspect that it happens because the notification area icons appear and hide and new programs open and close and which changes the amount of space available and so he rearranges things so that they match and apparently does not always consider the original sequence in which the elements have been added.  Maybe if you remove the Quick Launch toolbar and then add again, the order will reset (but that I know not - probably not in the original sequence, which I doubt is logged nowhere - it did not work when I tried it).

    Unfortunately, I don't have a solution to this problem (and I spend a little time looking for even before myselff posed the question) and do not believe that there is a.  It is also unfortunate that you can't move them so they can be put back in the right order if they change.  I don't think that there is nothing wrong with your system or that it is something that can be repaired or fixed - it's just the way it is and we just have to live with it.  I don't know any 3rd party software that controls the order of tabs open in the taskbar program (but you can check out Bing, Gooogle,www.tucows.comand www.download.com to see if I'm wrong on this - here n "t all when I looked trying to solve this problem for my own system).

    I'm sorry it wasn't what you wanted to hear, but it's like that.  I don't know if it's different in Windows 7.

    Good luck!

  • The battery takes only 10 minutes and portable life time stopping randomly.

    I have a laptop Toshiba Satellite with Windows Vista. I got it for about 4 years, and since a few weeks ago my battery life has declined rapidly. Once it is fully charged, I unplug the unit and he said that I usually have about 13 minutes remaining until I have to reload. The battery used to last nearly 2 hours. 20% remaining capacity, my computer is asleep at random and locks. I have to wait a few minutes and then press the power button / stop and type in my password again. I already have my plan of the battery power as "Power Saver" that increases the battery life. I was prompted to change my setting of peak power, which I did, with no result. Here's what my settings are:

    Critical battery action: sleep (cannot change this)
    Critical battery level: 1%
    Low battery action: do nothing
    Low battery: 3%
    I changed numbers autour and nothing seems to work better than anything else. I'm really angry at the short battery life and falling asleep randomly. Can anyone help? Should I get a new laptop or just a new battery?

    Hello

    4 years is a long time for a battery and degradation that you see is expected.

    Old battery? Unplug the power to the computer - remove the battery and clean the contacts with a pencil
    eraser (do not use this, if your battery is fine slots - just clean up the edges of the knife which fit in)
    them and be careful). Batteries are old, or it could be a problem with the computer.
    Check with the support of the machine system, and many of them have on line forums.

    New Lithium-Ion type battery usually last longer if you do not unload then less than 30%
    However on a laptop that not extend their life a lot. Best is to use the a/c adapter
    When this is possible.

  • My computer keeps showing random parts "suddenly stop working" and the computer needs to reboot - I think it's a virus.

    I have a problem when occasionally and randomly my computer components apparently all of a sudden "stop working and must close ' which translates into my computer restart itself. This happens a lot, but I can not associate with any particular issue, as it changes each time. I think it's a virus, but nothing seems to be wrong, it's just the inconvenience. I had the computer more than a year and nothing wrong with it. The only other common thing is a program called "twonkymedia" seems to be on my pc and "must be closed", but I can't find anywhere to remove it.

    It's driving me crazy now, as can happen at any time during the game, work or other passtimes of the computer.
