It is usally a program that overloads and like breaks a file fo the computer to restart. I don't know nothing about that. But if I take it slowly I have no problems. It might of been XFire. I was looking it up on here and XFire can cause the BSOD. What sucks is that I well paly my games with that. I am guessing the hours for that are a sacrfice I have to take until XFire is ready for 7. But I am just taking it slowly right now. Though I do still have one problem. I can't seem to get my computer to rate itself. Validtion passed and everything but it just shutsdown the rate. Says it isn't working and is finding soultions. What's ironic is that it was still rating the computer but it stoped everytime so I can't see my rate score. You got any ideas?
