New System Lockups

[DWright]

Put a new system together, parts listed below, and I just wanted a bounce this off you guys to see if you can see why whenever I run a game after about 3 mins or so come artifacts start showing up and then the video just locks up. Has anyone had issues with a similar setup?

P4P800 Deluxe
P4 3.0C
Mushkin 1 GB|PC3200 Dual kit x2
Windows XP
Leadtek WinFast A380 Ultra TDH ( 5950 ultra )

No other cards installed. New OS installed 2 times. Only happens in 3d applications. Latest Video drivers used as well as the ones that came with the video card. Default BIOS settings.

Please Advise and thanks in advance.

I snagged this from Zepper... you could have bad memory, try memtest86.com
Hope this helps

What brand/model power supply are you using?

I have a Antec 400w Power Supply. From all of my research that seemed enough and a good powersupply.

Thanks I'll run this prog to see what it can find. I have tried pulling 2 of the ram pieces and then swapping and then one at at time to see if it was one of the chips but it still locks up. :|
Thanks for your responses
