Win32k.sys bsod?

[zapoqx]

For the past 2 weeks, I would be getting this error of the Win32k.sys bsod. It would be a bsod where it says the file that caused the fault was Win32k.sys (usually if I get a bsod, I write it down, but this actually says the file?).
At first, I thought this was caused because a game. Then it has happened on 3 different games (1 that won't change resolutions and the 2 that can). So... I can only think its back when I tried installing the Omega Drivers and then found it a failure and uninstalled it and reinstalled the ATI drivers.


What does the win32k.sys file do specifically.

Also, if this is possibly related to the driver mix, is there anyway that I can find something to fully uninstall all traces to ATI drivers (Omega or regular) just to be sure?

Driver Cleaner Pro can remove all traces but it is no longer free.
An older version which is free can be found here.

looks like it was solved with the driver cleaner. Thanks American Zombie.
