[solved] Freezing and Looping Sounds

[tluu12]

Hi,
I'm not sure if this is the right section to be posting in, but I have this problem with my PC (specs below), occasionally, it will lock up completely, and the last 0.25sec of sound will be looping. It happens at random times; playing games, watching flash videos online, listening to music, or leaving my PC on overnight to download stuff and I come back to a frozen PC. I've done memory, GPU, and CPU stress tests, and none of which has caused a freeze. Any idea what can be done? I'm starting to lean towards replacing my mobo.

Specs:
CPU: Intel C2D E6750 > OC'd to 3.0GHz (I've done stress test on CPU at default clock speed and OC speeds.)
Mobo: eVGA 750i SLi FTW
RAM: 4GB Crucial Ballistix
GPU: 2x eVGA 8800GT SC in SLi
PSU: ULTRA X3 1000W
HDD: 2x 74GB WD Raptor 10k RAID0
Sound: Creative Labs Sound Blaster X-Fi

Well, sounds like a software issue honestly. I would run several virus scans, do a disk defrag, and update the drivers for everything, especially that sound card.

it seems I fixed the problem, I believe it was a bad overclock, and the memory timings were off. I downclocked back to stock and reset BIOS/CMOS as well, and it's been over a week and no freezes at all.
