    One of your errors was...
    Four of your errors are:
    Since all point to afd.sys, I would suggest...
    1. Run this comand from command prompt to see if all files on your system are correct, not corrupt: sfc /scannnow
    2. Check your Memory with Memtest... http://www.techspot.com/vb/topic62524.html
    3. Make sure your Drivers are updated... see if you find any with yellow or red flags in your System Properties | Hardware | Device Manager.
    4. Check for Malware... http://www.techspot.com/vb/topic58138.html

    since windows 7 is not officially out, this is probably a driver compatability error. Support will be limited until 7 is officially released.

    no, i do mean windows 7!
    and its my graphics card.. x1950pro
    beccause my computer is still running (music still playing) just that the graphics card drivers dont work properly?
    and is there anyway to fix it?
    its windows 7 RC, so it should be fully supported, and the ati website has dropped support for this now 'outdated graphics card' although its quite new!
    thanks for your help everyone btw, esp B00KWyrm!

    Download the latest driver for the X1950Pro that is certified to work with Windows 7, or at least, VISTA version 2.0

    i have tried, but it still causes the error... what if i install the XPDM drivers? i know they are stable, does anyone know how to install them? i get stuck with the error 'the drivers aren't for the operating system' but on microsoft it says windows 7 supports manual installation of them!
    thanks
