BSOD are rarely caused by software, and the one you got typically indicates that either your CPU is overheating or you have some bad RAM.
Download Prime95 and Real Temp (see Step 10 of the "Step-by-Step Guide to Building a PC" sticky for links). Run these for a few hours and see the temperature of the CPU.
Next, download MemTest86+. Burn the image to a physical CD and boot from it. Let it run overnight. This will test the RAM and see if it's all working.
After that, the troubleshooting gets a little more difficult. So try those and report back.
