What kind of PSU are you using and have you checked the actual power out it is providing? Have you run memtest86 (google it, it's a free utility) to test your RAM? These are the two most likely culprits. Also, make sure you're running a stable driver for your video card. Try 78.05 for a 6600 series.

Did the troubles start after you addd the PSU or the RAM? Also the age of either is irrelevant as RAM can be brand new and be faulty and cheap PSU can fail at anytime.
