Sorry it took soo long for me to respond. This did not start soon after a driver install, but the last thing i installed was catalyst, i have reinstalled it again and i stopped having blue screens, but tonight i started GTA IV and left my computer for a few minutes, when i cam back it had restarted and i had blud screened again. This one really worry me because it says the problem was "hardware". Here is the analyzed minidump
