possible power supply overload?

[CruisD64]

Hey, I noticed when gaming heavy i get the occasional glitch ingame. I JUST got my Opteron processor today and have been experiencing some minor artifacting in Call Of Duty 2.

Specs are:

Opteron165 @ 2.6 -> 1.375v (Zalman 9500 cpu cooler)
eVGA NF41 SLI
1gb Patriot DDR400
XFX 8800GTS (600/900)
3 Harddrives (2x120, 1x160)
4 Fans, 2 Cathode lights
Lite-On 16x Dual Layer DVD/RW
Lite-On 52x CD Burner

all being powered by an Antec NeoPower 480 watt PSU. I put all the clock settings back to stock when I first noticed this artifacting and it still happened. Ive only noticed it in COD2 and it happens maybe once every few minutes where I'll see like a black artifact for a split second. Could it be driver issues perhaps? Lemme know! Thanks!

PSU is fine, how hot is the vga while running cod2? maybe tune the fanspeeds up with atitool or similar app

My GPU idles at 58 and under load (using ATI Tool) peaks at around 74. Seems a little high but apparently these videocards run hot. I'm using nTune to keep the fan speed at 85% all the time (compromise between performance and noise).

Anyways, I figured actually figured out the problem since i posted this thread. I pulled the chip out and put back in my X2 3800 @2.4 and ran COD2. No problems whatsoever. While I was doing this, I took a better look at the underside of the Opteron and noticed there was some thermal paste connecting some of the pins. I guess the previous owner was sloppy. Good thing it didnt fry my comp! Anyways, I removed the paste using a soft toothbrush and Arctic Silver thermal remover. I then used isopropyl alcohol to get all the oils off and used a blow drier to make sure the chip was dry! Now I'm typing this while Prime95 is running and so far so good! Been about 20 minutes (i know, thats nothing for this program) and its already passed a test that it failed before. I'm doing the test thats CPU intensive to get those temps high and the hottest its gotten is 53. Previously, it was hitting 62! Unbelievable! I was about ready to give up but looks like things are good. I'm hoping to get 2.6 out of it at 1.375 so i'll be priming at that speed overnight. fingers crossed . Anyways, thanks for help!
