I CANNOT figure out this gpus problem...

Okay after running WHOCRASHED the main errors seem to be in the drivers atikmpag.sys and atihdw76.sys.

Unfortunately after the last installation of these drivers the system went bluescreen. Here are the results from whocrashed.

It's not the psu. I've recently upgraded that to an evga 600B 12v. It only crashes during gameplay. At times I can play for hours, and other times I can play for mere minutes before it decides to crash. The problem is that when I reinstall the drivers the client either crashes to bluescreen (the most recent error logged in whocrashed) or it completes and says "there were problems". Clicking the log details nothing through catalyst and at the very bottom of the log entry it says "driver install failure" or something to that measure.
