Last night I did a clean install of Win 7 Proffesional 64-bit... But I keep getting bluescreens at random intervals. First I thought it might be the graphics driver that Windows Update supplied, so I tried installing a driver directly from nVidia's site which hasn't made any difference. When the OS restarts after the BSOD, it obviously brings up an error report (which i've posted below) and the option to 'Find a Solution' which when clicked doesn't actually do anything. The only programs that I have constantly running are: NOD32 & Steam.
