I had a friend build my brother-in-law a computer, and it keeps randomly getting the dreaded BSOD. It ran Crysis for an hour, and then crashed. I load up email, it crashed. It's got all of the updates and drivers for audio/video/chipset/ etc etc.
Here are the specs:

Which exact RAM is in the system? You should manually set the RAM speed, timings, and voltage to their rated values in the BIOS. Memtest86+ is good at detecting faulty RAM, but not great at detecting incorrect RAM settings in the BIOS.
