Problems w/ my new computer

[dragonfly522]

Actually, the HDD and CD-ROM are a few years old. This is what I purchased:

CPU: AMD Phenom II X6 1090T
video card: ATI Radeon HD 6850
RAM: OCZ 4 GB 1333 MHz
mobo: BIOSTAR TA785G3

and I use Windows 7 64-bit. Any other info. about my build you need let me know. I did some overclocking a couple of months ago with the new CPU, mobo, and RAM. I hadn't bought the new video card yet. I may have damaged the CPU and I want to test the CPU using Prime 95 to see how long each core lasts before they fail, but I can't keep the display on long enough to do this. It goes black after I use it for 20 minutes or so. It periodically goes to the BSOD. Would a damaged CPU cause a display malfunction? Is it possible that I don't have enough RAM? Please tell me what steps I can take to solve this problem.

You have plenty of ram. What is your CPU current clocked at? what are the temps? try restoring it to stock settings and see what happens.

The CPU is at stock speed and the temps are fine.

It's very hard for me to comment at this point because I'm not clear what you are saying.
This may be my fault partly, but you could organize your thoughts better and give a complete arts list and I'll have a go at it in the morning.

This may help:
