Computer Freezing, new info, please help!!!!

[socratitties]

My computer is freezing randomly. Temp doesn't go above 50 celsius. My computer is a custom from Ibuypower. Symptoms have arisen in past two weeks, computer if 4 months old. I run Spybot and keep the system unclogged.

Windows 7
AMD Phenom II x4 955
Asus M4A78T-D AMD 790GX
Corsair 650w
Powercolor HD5570 1GB Video Card
500GB Sata-2 WD5000ks
[core i7-DDR3] 2GB DDR3 - 1600 GAMING SINGLE, two of them
30" Dell monitor.

The problem is happening randomly. I had one online video going and opened up Windows control panel and it froze. Sometimes when I'm multitabling online poker. I can't run Prime95 stess test without a crash. Crashed while running Spybot.

-I've reinstalled the latest ATI and Adobe drivers.
-System runs on highperformance setting
- CPU? Motherboard? Vid Card? Power supply? Any way to test?

Here is the Ram info if wanted. Please help if you can. I work off my computer and lose money whenever it crashes. Thank you very much.

Download a copy of memtest, burn it onto a cd and boot off of it to check your RAM for errors. If you have a memory stick going bad it can cause strange crashes.

Ran memtest. No errors.

How many passes did you run it through? A mostly good stick might not throw errors until the third or fourth pass, a fairly bad stick will throw quite a few errors in the first pass. Generally its recommended to run it for 5 passes or overnight to rule out any errors, also make sure you have it running at the recommended voltage for those sticks.

Check to make sure that all your cards are sitting in the PCI PCIE slots properly. Make sure that your USB Ports are not damaged and earthing out the Motherboard. Make sure that your PSU is not dropping voltage (some BIOS supports this by showing voltages.)

Ok, thanks for the suggestions. I've taken it into the shop. I reformatted and reinstalled Win7, ran Prime95 and it froze in a few minutes. Hopefully they can get it going.
