System locks while gaming

[Yavitz]

A few days ago I just upgraded to an X1800xl from my GeForce 4 Ti 4800. Everything seemed to be going well until I started to play games. While playing a game it will freeze at random times, usually from 5-10 minutes in. At first I thought the GPU was overheating however after some researching the temerature problem was a driver issue. Next I installed the 5.10a omega drivers. Still no help. My cpu is runing at 44c and my gpu is around 56c. So I dont think it's a temp issue. Checked BIOS settings but everything seemed to be right. Im down to thinking it might be a PSU or RAM issue. When I was shopping for the PSU it says its rated 20a for 12v yet on the unit itself it says 15a. Any thoughts would be appriciated I'm going crazy here. My specs are:

Asus K8N4-E Deluxe
ATRIX COLORSit PSCI-500-GREN ATX 500W Power Supply
Athlon 64 3400+ (Venice)
1Gb pc3200 Corsair ram (2x 512)
ATI x1800xl
34 Gb Raptor
NEC ND-3540A DVD Burner

Try your new vid card in another system?

See if you can borrow a power supply from a friend and try it in your system. I've never heard of ATRIX, did you do any research on them before buying?

Unfortunatly I really didn't have the cash to get a good one at the time. And now I am definatly regreting it if it is in fact the problem. Also I can't test my card on a friends because no one I know has made the switch to Pci-E yet.

Did you use Memtest86 to test your memory? Let it run for like 10 hours?

I ran memtest for a couple hours but not that long and it didn't detect any errors but I can leave it on overnight tonight. Also the memory is not new and has worked very well for me for over a year.
