  • First of all what is your graphics card? Make sure to get the latest drivers for Windows 7 like Chris had mentioned. Some drivers aren't totally compatible with Windows 8 as well. In my case, I have an Intel HD graphics card in my HP tm2t-2100CTO, and it doesn't work with any of the driver versions. The only work around was to disable and re-enable it in the Device Manager (search for it under Settings...). Be sure to keep an eye out for newer drivers as they may solve your issue.

  • CYRAX2011,

    I am sorry to hear about your issues, have you downloaded the most current video and audio drivers for Windows 7 from the manufacturer’s website?  If not then give that a try to see if it fixes your issues.

    If that doesn't work, then try to install the drivers in compatibility mode to see if that resolves the problem.

    You can do this by:

    ·         Enter the Start screen

    ·         Move your mouse to the bottom left of the screen to expand the Charms section

    ·         Select Search

    ·         Type Compatibility

    ·         Click Settings in the right column

    ·         Click Run programs made for previous versions of Windows

    ·         Then follow the prompts and direct the troubleshooter to the installer for your computer's driver.


    Let us know if this helps.

    Thanks,


    Chris
