I have had this issue with a few versions of Windows 7, but it has never gone away. The current version is 7100. I have updated my drivers. Graphics card is ATI X1250 Anyways, the issue is every now and then, the screen will just go nuts, and then the computer will shut down. Before, when I updated, this would stop, then I would be getting Bad Pool Header BSD. Now, it just wont go away. The screen thing is really annoying, if anyone knows what to do, please tell me.
