Okay, after a bit of searching on Google, and a download of SpeedFan, I have ruled out my hardware is overheating. However, I'm not sure if it's due to RAM or anything.

If you didn't happen to read my last thread:
Every few minutes, usually while doing something, my screen will randomly go black after a few seconds of freezing. I've updated all video/display drivers, checked my temperatures, my case is clean on the inside as it's a brand new case, etc.

Does anyone else have some ideas? The HDD was just reformated not too long ago and I haven't been connected to the internet on it for long, so I doubt it's a virus.
