  • Constant freeze (on IE9 and mozilla and media players) after the updates of windows, please help?

    Hello

    I have a bit of a situation, which I believe can be due to windows updates. I'm not very experienced with computers, but I know that I have no viruses on my computer, or malicious software, and I have corrected all the mistakes of registry. I have a dell xps l702x, i5 2.4 GHz, 8 GB of RAM. I had this problem for over 2 months and I just ran out of options on how to solve this problem. I reinstalled windows 7 all about 3 times over 2 months, and I have an idea about what's going on. My computer's internet browsers, which means of IE9 and mozilla firefox keep freezing when I use them. I tried to use internet explore with no. Add ons, without success, as well. I have a few movies downloaded, to freeze when I try to play them in VLC Player. When I re-installed windows 7, I used my pin code files for install base running programs. After windows updates (which were just of securities system and IE9) I started having the gel. It seems that some program moves data to and from the hard disk are the culprit. If I opened IE9 and it loads the homepage, if I move my mouse it freezes instantly, without ctrl + alt + delete to help me.

    Help, please!

    Do not use the programs OWN more.  They do little good and can cause problems.  What may happen, it is that these programs can find registry entries that do not appear to be used, then remove them.  MS has put some of these here for future use, and when the updates come and try to use entries that has removed the vacuum cleaner, you encounter this kind of problem.

    It is also possible that you may have an overheating or other related materials the problem, but if you have used a cleaner program, I would try to reinstall and do not use it to see what happens.  If that does not resolve the problem, you can check the time with SpeedFan, run the memory diagnostics, run drive Diagnostics, run chkdsk, etc., but reinstall without the program cleaning everything first.

    Also, you need only to download drivers from Dell, not Intel or update MS or anyone else.  This is another way people get into trouble.

    Good luck.

  • Very slow download after the update February 10

    After the update automated around Feb 10th, photos are slowly and web video a crawl - for every one second of game-playing, it hangs for 10 seconds or more.

    Download Adobe software update takes forever - about 10 kb/s or less. Everything slowed to a crawl.  What is going on?

    I have a DELL reconditioned with XP and a custom-built Q8900 Intel Vista and it happens on both machines.

    I think of restoring to the point of pre-2/10 but do not want to be vulnerable.  Any person with knowledge or patch fix, feel free to post... help!

    johnnydj,
    After testing mode safe mode with networking, I suggest that you make sure that your NETWORK card drivers are up to date.  You can also see if there is a firmware upgrade for the router you have.  Alternatively, you can perform a clean boot to see if other software can interfere with your system.  Also, make sure that your security software is up-to-date.  Mike - Engineer Support Microsoft Answers

  • Blue screen of death after the update installed at startup upward.

    I have windows xp sp3 after installed updates don't know which ones, because the installed when I stop and 52 of them there I now get a blue screen of death which says:

    Stop: c000007b {bad image}

    The application or DLL? \c:\windows\system32\winsrv.dll is not a valid windows image. Please check this against your installation diskette.

    I can't go to the safe mode get the same error and same with the last known good configuration. I can't even to safe mode command prompt, system, or debug mode recovery still giving me the same error. I repaired windows 3 times already and the same thing happens each time after that some update that I don't know he messes all this. Give me advice. I have antivirus Iola system mechanic. I think just to wipe the entire disk and do a clean install if you do not have anything else to tell me I'll do it, but I don't know if that even the problem will be solved because there seems to be a problem of windows software update. I also notice from the internet explorer 7 installed it stops working a few flashes upwards on you whenever you try to open it up if it's maybe part of the problem too. I do not plan to let internet 7 install go into all this time.

    Install the updates one at a time or 5 at the time may not be a bad idea.  Then when it breaks watch you and see if one of those is eager to replace your winsrv.dll file.

    You said you DO or DO NOT have to System Mechanic configured to run at startup?  Sometimes after installation of the updates, who see the new files (and if they are obsolete), can interpret the new legitimate files to be a threat.  If you could get started and uninstall that (at least temporarily) that would eliminate this possibility of this equation of many variables.

    The Dell has a number of service tag sticker and if so what does it say?  You can search for things by service number

    You should make a bootable CD of XP (no XP media required) Recovery Console.

    You see, Microsoft support engineers won't tell you how to do this either - since there is not an article of KB Microsoft Bing and link to.

    If you have a SATA drive, which will give you another challenge because you need to maybe get into BIOS and temporarily change the disk other than SATA configuration mode so the Recovery Console will be able to see, replace the suspicious winsrv.dll file, change the SATA drive and reboot...

    First, do the XP Recovery CD of Console and if you are able to use a system of work to ensure that the CD you made at least boots (you don't have to "do" something with it), which would be a good thing.

    Here's how:

    If you have no XP bootable media (or aren't sure you have) create a bootable XP Recovery CD of Console and do not forget.

    This is not the same as recovery disks that might have come with the acquisition of the system store.

    You can make a bootable Recovery Console CD by downloading an ISO file and burn it to a CD.

    The ISO bootable image file you need to download is called:

    xp_rec_con. ISO

    Download the ISO from here:

    http://www.mediafire.com/?ueyyzfymmig

    Use a new CD and this simple and free program to burn your ISO file and create your bootable CD:

    http://www.ImgBurn.com/

    When you install ImgBurn, DO NOT install the Ask toolbar.

    Here are some instructions for ImgBurn:

    http://Forum.ImgBurn.com/index.php?showtopic=61

    It would be a good idea to test your bootable CD on a computer running.

    You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.  These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

    When you start on the CD, follow the instructions:

    Press any key to boot from CD...

    Installing Windows... going to pronounce.

    Press 'R' to enter the Recovery Console.

    Select the installation that you want to access (usually 1: C:\WINDOWS)

    You may be asked to enter the password (usually empty).

    You should be in the folder C:\WINDOWS.  It's the same as the

    C:\Windows folder that you see in Solution Explorer.

    The Recovery Console allows base as file commands: copy, rename, replace, delete, chkdsk, fixboot, fixmbr, cd, etc.

    For a list of the commands in the Recovery Console, type help at the prompt of commands or read on here XP Recovery Console:

  • Fans of fast and slow mail after upgrade of Sierra

    So I too just upgraded to Sierra, and I have two problems.  The first I noticed almost immediately after a reboot is something is causing fans to run almost non-stop.  I looked at the level of the console and I see that several root applications use more than 100% of the time CPU.  What the hell is happening here?

    Second, Mail has now slowed down to the point that it is almost unusable.  I click on an email and it will literally be anywhere from 15 to 20 seconds for the mail to open.  Not a complex HTML with email of old thing plain video simple.  What the hell is happening here?  It's maddening.

  • Defective touchpad (Synaptics) and slow computer after extended use (memory leak)

    Two problems have been caused with my HP Split 2 x since I bought it 2 months ago:

    (1) the touchpad works sometimes for a few seconds, while the touchscreen still work OK.

    (2) the computer becomes slow after a while of use (which varies from a few minutes to a few hours usually). The Task Manager shows 98%-99% of memory, most of which use (3.6 GB / 4 GB) are not paged memory.

    I suspect the two issues are related to a faulty Synaptics driver, according to:

    http://h30434.www3.HP.com/T5/notebook-operating-systems-and-software/envy-X2-non-paged-pool-memory-l...

    and http://forum.notebookreview.com/razer/731374-memory-leak-synaptics-driver.html .

    I did the same test as the second link with the same result: Open "Task Manager" (Ctrl-Shift-Esc), on the 'Performance' tab, select 'memory '. Note the value for "Non paged memory. If I move the touchpad, it increases to about 1 MB every 5 seconds. If I stop moving, the value remains constant.

    I use the preinstalled Synaptics driver, version 17.0.10.9 (Sep 06, 2013) for 64-bit 8.1 window.

    Everyone has the same problem, or use it without these issues?

    I would like to know if a restoration system or factory reset may fix.

    FINALLY!

    Microsoft has just released an update for Synaptics Driver, not thanks to HP which has not found a way to provide the possible Synaptics driver as an OEM update.

    Update Windows Update to Sypatics HD TouchPad two days ago, but I would not be allowed to install as it kept then mainly in giving the 800F0100 error Code. After some research on the Internet I could find that an installation manual after the WU has downloaded the driver would be possible.

    So I went to the Device Manager > mice and other pointing devices > TouchPad Synaptics HID > properties > driver > Update Driver > Browse my computer for driver software and shown the finger/windows/C:\Windows\SoftwareDistribution/Download and everything worked like a charm = D

    I have no more memory leak and now after SEVEN MONTHS I finally can use gestures that it was supposed to.

    But I still annoyed gel problems which in my case is a dysfunction between the screen and the dock.

    Just that you wanted the guys at Microsoft to know is the solution, not the HP that would have had if they have signed and put the driver since November last at our disposal. Blame it on you, HP.

  • Spotting and slow system after a few clicks

    Hi all

    I just wanted to draw your attention to a very annoying problem. If you use the function of spotting several times in a session of lightroom, you end up with unable to use it more if you don't come out of lightroom and start from scratch.

    What I mean is that, after a few clicks on the spotting on 2-3 images, when you use again the number of photo 4, for example, the function is almost unusable (very slow movements that make it impossible to put the tool spot in the right place).

    If you then exit lightroom and try again everythimg is fine for awhile. It seems that it is allocating memory every time that you use IT... everyone is having the same problem? No idea how to fix? I've dealt with that since previous versions, and it has never ben resolved (if it is indeed a bug!).

    Thank you all!
