My iMac doesn't work that in safe mode, normal mode the screen layout is really weird. Help, please! :)

Hi guys,.

Since yesterday my iMac 27 inches of the end 2009 has acted weird. Text was not good more visible and popupscreen were empty, white or black. (do not know why they are uploaded in reverse)

Then I tried a clean install. Screen was working again fine. Then formatted my drive and installed the new OSX.

Download went fine, but when installing the pop-up screens were not visible.

After a few random reboots on my side, it worked again.  Thus, installation...

But... Now, I always have the same question. In safe mode, everything works fine, but in normal mode, the screen is *. Pop - up screens are blank/black or white, the numbers are mixed, etc. What it can be.

I already installed it on an external HARD disk, reset the SMC and the PRAM, Test hardware (message only 1 failure: 4sns/1/40000000: TH00 - 9,000.) "But I think it's because I installed my SSD later, that's why I need to use a program like HDD control to control the fan).

so... What can be? I've tried everything! If any of you guys could help me, I would like to do a happy dance ;-)

You have a sensor error. You can make an appointment at the Apple Store - Genius Bar store and bring it into service. You can also search an Apple Store - find a store - Apple.

  • my laptop doesn't work well in safe mode... How do I please you? It's a laptop Dell 1520

    Please guys my laptop using windows vista premium to household use and windows is not in time on normally I can only log in safe mode... Wen he lights up normally after about 30 minutes, it remains on my desktop screen and nothing, when I click to go on the internet it wount is wrong, it does nothing I hv tried updating drivers, System Restore last good configuration to boot but nothing still, actually worse... Please I need your help...

    What I proposed is to understand what is causing the problem. If you start windows with a single process from the start, when the problem occurs, regardless of the process started would be the problem. Basically, it's a slow process of elimination. So, if by "back to what you said, I do now" you mean that you are going back to windows startup with 1 single process on the list, ranging from 1 to the time to the bottom of the list, then of course continue.

  • Stuck in Safe Mode - Vista - viruses? Driver problem? Help, please

    I'm operating Vista Home Premium and only the system starts in Mode safe.  Several vertical lines in a model of 5 show on the screen as it tries to start. He is stuck in a loop of repair of unsuccessul attempts but I can't us F8 to go into Safe Mode, no problem.

    Normal system repair did not work. System Restore to a watch in which the system was working did not work (went back 2 weeks).  I thought it might be a video driver error, but new updates of drivers did not fix the problem still could be the problem?  It will not Norton scan (although my anti virus has expired four days before what is happening). I uncheck all startup items and confirmed that in Normal Mode with the system configuration. None of this has worked.

    I bought an external hard drive to transfer all my data on that I agree with setting back to factory settings, but it will not recognize the new external drive in safe mode.   -Why is this?

    Any help on these two issues would be much appreciated!  Pulling the last hair on my head!

    Hi ColtsBlue,

    ·         Did you of recent changes on the computer that could have caused this start happening?

    ·         Are you able to scan the machine with something other than Norton?

    I suggest you try the methods below and check if it helps.

    Method 1: If you have the disks for Windows Vista try a startup repair and verification.

    http://Windows.Microsoft.com/en-us/Windows7/products/features/Startup-Repair

    Method 2: This can happen if the video card drivers do not work or is corrupted so uninstalling and reinstalling might solve the problem several times so try uninstall the drivers from Device Manager. Follow the steps below:

    1. Click Start, in the search box type Device Manager and press to enter.

    2. Device Manager window opens, expand sound, video and game controllers.

    3. double click and go to the tab drivers.

    4. click on the tab to uninstall to uninstall.

    5 restart the system, it will reinstall the drivers again.

    Method 3: You can uninstall Norton and install Microsoft Security Essentials of Microsoft and check if it works very well.

  • iMac works fine with safe mode only

    iMac works fine in safe mode, but in normal mode, it freezes constantly, the wheel that turns, the freezing of the apps, and when I try to restart, it gets stuck. I have to hard reboot. I tried to reinstall the operating system, which did not help. I have reset the NVRAM, but it has not solved the problem. I came across another post in 2013, with another user who was having a similar problem. There are detailed instructions to run diagnostic tests via terminal and display the results. This seemed to fix the problems of the user, but I don't know what to do with the information it generates. I have an iMac 2009 El Capitan 10.6.11 running. Can someone help me understand what the problem is?

  • Windows Vista hangs after choosing the identity of the connection. works well in safe mode

    I was able to start windows in safe mode, and then create a new connection profile.  However, Windows doesn't always starts normally.  Using the original profile causes the screen to go black after the "Welcome" screen  Using the new profile causes the screen to go to blue after the Welcome screen.  It's a laptop with nothing fixed.  everything seems to work fine in safe mode, so I think it's a matter of profile.  There is no restore points, so I can't use system restore.  Any thoughts?

    Hello Ripplemaker1,

    I have to agree. This sounds like it may be some kind of malware in game.

    I recommend you create a new thread in the forum security, privacy, and user accounts for this piece of the puzzle.

    Hey janicem42177174,

    Adobe does most support the installation and use of Acrobat 6 because it is a very old version that is not compatible with Windows 7.

    I suggest you to please use the latest version of Acrobat 11.0.10 is perfectly compatible with your operating system with its functions and improved functions.

    You can download a free trial version of 30 days of Acrobat from here:

  • ox00000050 of error that no safe mode cannot open a session and I don't have a cd rom

    updates installed a few days earlier, after reboot goes to a blue screen and gives me this error, he won't get in any mode, and I can not restore because I have not a cd rom, anyone know how I can get the cd of restoration on a USB key, I tried regularly copy paste , and it did not work...

    danna001,
    Thanks for posting with us.  Unfortunately, you're going to need an XP CD or disk recovery supplied with your computer.  If you are unable to get the Safe Mode options by pressing F8 during startup, or no options doesn't work, then you must start with the CD.  Put it on a key USB will not help you.  Most PC manufacturers will sell the disc of recovery for a reasonable price.
    Once you are able to get a CD, you must boot into recovery mode and run "SFC/scannow".  Here is a link that explains the System File Checker tool: http://support.microsoft.com/kb/310747 Mike - engineer Microsoft Support responses

  • TV connected via the VGA input to HDMI don't get no signal after preparing the Windows message, works fine in safe mode

    Original title: PC to tv connection / VGA to HDMI

    Hello
    I hope someone out there can help. I recently bought a new samsung TV after that my old one failed. My new TV doesn't have a RGB port to connect a VGA cable to so I can use my PC as my old one done, it has HDMI and my PC only output VGA. I bought a VGA Converter HDMI to maplin and when I start my PC the image appears on my TV because it goes through its startup upward. It displays windows prepares, but then the Windows point would open normally, the signal on my TV dies and it does is display the message no signal on the screen. If I start thr PC in safe mode, windows starts very well and the signal does not go down. I use windows 7. Someone knows how to fix?
    Thank you

    It is possible that your computer is trying to send a resolution & frequency to which the TV cannot manage.  I suspect that this is because the image is displayed when starting, but then disappears when Windows takes control - until Windows takes over, the resolution sent will be below.

    You should consult the manual of the TV to its specifications.  Mine, for example, just a a simple table of resolutions & combinations of vertical frequency it can handle.  Then look at the Control Panel, display, change display settings to see what your computer can produce and choose one that fits these two machines.  If the best resolution display settings don't work then go to the next best resolution [or in the setting of 640 x 480 to see which works best].

    Once configured, Windows will display the setting chosen at the television screen every time so you will not have to keep setting up for each session.

    Each time that you connect the TV you can use the Windows key + P key combination to toggle the display.

    I don't know if you want the TV an extended desktop or a single view.  You might find, as I did, that the TV can use a higher resolution output if it is the only view.  I suspect that this is a result of capacity of the computer's display adapter because it has less work to do if there is only one required both display.

    Once you put in place, you may find that control panel display settings, display, change, advanced has useful additional parameters, but you'd probably need to have a good guide to help with your graphics card make any sense of the options available.

    If that is not enough then I suggest that you try to find an online forum for your TV, hoping that someone has done what you are trying to do.

    Good luck

  • BlackBerry Smartphones not able to get my phone to work unless in safe mode

    There are two problems I see. Yesterday, I've updated througn Office of BB online. I have now deleted the BB 7.1.0 CoreApplications four times. When I start my phone one of the two things happening. I can enter my password, but when I hit the key enter the phone crashes and will only go to safe mode. The second thing that happens is it accepts my password, but immediately the following message - Eception Exception: Java.Lang.Error there is an option to click OK but when I get my BB freezes. I have installed and uninstalled all languages twice, I restarted a dozen times or more, I reinstalled a version more ancient dating back months and not seen no change to these questions. I can work the phone in safe mode, but this isn't a solution. I find this very frustrating. I would also like to be able to talk to a human being on this subject but can't find a number on your website. A WTF happening? I'm about to launch this phone in the tray and get an IPhone!

    Hello and welcome to the community!

    I think that you may need to perform a clean reload OS... from your post, I can't quite tell if you did that.

    Please visit this official download portal as you go along. If all you want are the levels of BONE, it is first sorted by carrier - the carrier supports, your search will be fast. However, some carriers are much slower than others to release updates. To really get the package up-to-date OS for your BB, you need to dig through and find all businesses that support your specific model BB and then compare the BONE levels they support.

    From a PC, you can install any compatible OS package (for example, for your BB model exact number) of a BB via this procedure:

    Note Although written to "recharge" and the storm, it can be used to upgrade, downgrade or recharge any BB device model - depends on the operating system package you download and install on your PC. After installing the operating system on your PC package, please remember to remove all copies of the SELLER on your PC. XML... There will be at least one and maybe 2, and they will be located in the same way or to (it changes based on your version of Windows) these files:

    • C:\Program Files (x 86) \Common Files\Research In Motion\AppLoader
    • C:\Users\(your Windows username) \AppData\Roaming\Research In Motion\BlackBerry\Loader XML

    Don't forget that you remove, since your PC, any other BB OS devices as packages with more than one installed on the PC can cause conflicts with this procedure.

    You can also study the use of BBSAK (bbsak.org) to perform the wipe what he is capable.

    You can also try the "skeleton OS Reload procedure" in an attempt to circumscribe the precise causal element:

    1. Load your OS "bare bones"... If everything is optional, do not install it.
    2. If the behavior is immediately, then try another OS with step 1
    3. If the behavior does not immediately, then run for as long as necessary to make you to be sure that the behavior will not occur.
    4. Add one more thing - no matter how tempting, one.
    5. If the behavior does not immediately present, and then runs for long enough to be sure he won't have the same problem
    6. Repeat steps 4 and 5 until all things are responsible or the behavior presents

    When the behavior shows up, you know the culprit... the last thing you have loaded.

    If the behavior doesn't re-present, then you know that step 1 or 2 cured it.

    If the behavior has anything, then you have probably a problem of material level for which no amount of OS or software can heal.

    You may also use these tips:

    If you are on a MAC, you are limited to only your sanctioned carriers OS packages... but can still use any level they currently have to sanction. See this procedure:

    Please refer to this information, which is at the top of each page on this site:

    Contractually, BlackBerry cannot provide any support from first line for nothing. All support first line begins with mobile service providers, to the place of origin of purchase or an authorized service center (it varies according to the region and the specific question). When you bought your device and the services, you should have been informed about your methods of formal support... If you weren't, you need to check your place of origin of purchase or your service provider mobile as to what those who are for you.

    Good luck and let us know!
