If I do anything graphically intensive - any sort of game or streaming a video - for a few minutes my computer tends to freeze, give a brief blue screen, and then shut down on its on. I was told previously that it had something to do with my computer's older power supply kicking the bucket, but lately I've gotten a few error MESSAGES concerning my drivers failings. This is the information I receive after my computer reboots.

I'm more than happy to drudge up any additional information if it'll help troubleshoot, but beyond this I'm not sure what sort of INFO would be helpful or harmful. Quote
