Vista turned to grayscale

I was watching a movie on my computer on my TV with 2 monitors allowed. After that I turned off the TV and unchecked it in the control panel Nvidia, my whole system turned black and white. When I start the computer, the login screen is in color, and a few seconds after I log in there is color. Except that everything is black and white. It is not the theme or color settings I can say the research. Help!

Uninstalling the driver works, but as soon as he returned, he came back to grayscale. I tried a few times and kept getting the same result. The driver update does not work either (and I have the latest driver).

In my case, it turned out that the Nvidia Control Panel had for some reason any changed the Digital Vibrance setting to 0%, making it monochrome. I restored the default of 50%, and everything seems fine now.

    3. under programs, click on uninstall a program.

    4. in the pane tasks, click on turn Windows features on or off.

  • Update Windows Vista turns off my sound

    An automatic update of Vista took place on March 12, 2009 and after that my sound does not work (no matter what program was used).

    I used the system restore to choose a restore before March 12 point and this has restored the sound that works perfectly again.

    However, probably my automatic update system will soon install the same update to Vista and I will lose her again!

    My system seems to be (read from the Greek of invoice - all for me!):
    Bicoeur Intel Core 2 Duo E8300 processor
    with PCI-Express Nvidia GeForce card mother Intel Core 2 Duo/Quad Core MAXT
    with 256MB nVIDIA GeForce 8400 GS - DVI TV - Out HDTV
    HD onboard card its 5.1-6 channels his cinema

    Can anyone help?

    Devonsarrie,

    Have you checked to see if you have the latest drivers from the manufacturer of your motherboard sound card and or computer? In addition, it is difficult to diagnose what exactly happens if he is yet to break. I could autoupdate once and see if you or do not have the same results with your sound on your computer. If he does go back, check your drivers and make sure you have the latest version. After that, we can find out what caused the pilot of its operation and how we can go fixing it.

    Thank you

    Hi George,.

    Thanks for posting your query in Microsoft Community and we can help you with your problem.

    According to the description, you are facing problems with turning on Windows Defender. To help you to propose measures to solve the problem, I would appreciate if you could answer the following questions:

    1. what security software is installed on the computer?

    2 did you do changes on the computer before the show?

    You must have security (anti-virus) software installed on the computer.

    More than ONE cause of slow system, freezing injuries, programs not to work properly with Microsoft Security Essentials (MSE) disables Windows Vista Defender as MSE has its own integrated version in Defender.

    You can follow the steps in the article mentioned below and check if it works:

    Hi EddieLopezA,

    ·         Which version of Windows Vista is installed on your computer?

    ·         You have antivirus software on your computer?

    This problem may occur if another utility or service, for example a virus check program or a program disk monitoring, locked the partition before you try to run the Chkdsk.exe or Autochk.exe utility.

    I have some steps that may help you.

    Method 1: I suggest you to turn off all third-party applications and check if you have a similar question.

    To do this, follow these steps:

    1. open the start search box, type services.msc and click OK.

    2. in the Services (Local) list scroll the service concerned (for example auditor of virus or disk monitoring tool).

    3. right click on the service and select Properties.

    4. change the startup type to disabled for all applications 3rd - party that could be the cause of the blocking of Chkdsk problem.

    5. click OK/apply.

    6. restart the computer.

    Method 2: If this does not help, try to change the registry value and restart the computer.

    1. click on the start search box, type regedit.

    2. in the Publisher of the registry under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

    \SYSTEM\CurrentControlSet\Control\Session manager

    3 change the Boot entry run of:

    autocheck autochk * /r\DosDevice\C: (or other)

    TO:

    autocheck autochk *.

    Note: Change the settings of the REGISTRY can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the REGISTRY settings configuration can be solved. Changes to these settings are at your own risk.  If you want to edit the registry to fix this I urge you to back up your registry before proceeding.

    Microsoft Security Essentials has its own integrated version of the defender and should automatically disable the version of Vista in Windows Defender.
