Graphics freeze, sound loops

[Zalev]

Hello.

I recently upgraded my computer, which became a major overhaul.
It was all very exciting, until I had it up and running.
I tried to play Half Life 2, and after a few minutes, the screen froze and the sound stuck in a loop. Then I tried a different game, UT2K4. same thing. Quake 3, same thing. every single game i tried did it. I started trying to ascertain the problem, with benchmarks. 3dmark05 caused the same issue (without the sound). As did the FFXI benchmark.

My setup is
AMD Athlon 64 3200+ (Winchester) socket 939
ASUS A8V-E SE
ATI RADEON x850 XT PCI-e
2 Kingston 512 RAM

I ran memtest86 and after 10 hours, there were 0 errors.
It runs xp64 without a hitch.
I have the latest Catalyst drivers, CPU driver,
and BIOS.
I think it's either an issue with either the video card, or the motherboard.
Does anyone have any suggestions?

Firstly did you connect all fans up and are they all running. This is typical of a thermal problem. Plse check all fans and let me know what you find.

i agree with psyth, that sounds like you may need some better fans or better cooling methods.
