New build randomly freezing...urge to kill growing

I recently splashed out in the OCUK store and built a new system (specs below), but there's an irritating problem.

The build went fine without any probs, built on a grounded dissipative ESD mat with wrist strap to avoid ESD jip. After a few days it has started freezing up seemingly randomly.

It doesn't happen that often, maybe once or twice every 2 - 3 days. When it happens in windows it just totally freezes up: no BSOD or anything just no mouse or keyboard reaction, forcing a switch off switch on again. It can happen after I've been using the PC for ages or just when it's been sat switched on for a few hours unused. When it happens whilst gaming the screen just goes black with a few random red dots showing, or sometimes just freezes up in a menu screen, again it can happen after hours and hours of MOH Airborne or Crysis, or after just a few minutes.

I tried to run some diagnostic tests (Memtest86 etc) overnight from a bootable CD, but it must have rebooted because the next day it was sitting at the first menu from the CD. So it seems somethings not right outside windows which makes me think it's maybe a hardware prob.

Temperatures & voltages all look fine in ASUS PC Probe II & ASUS AI Suite, and the 8800GT sits at 60-61c idle climbing to about 69c under load.

The only obvious weird thing that has happened (about 3 times) is the sound going (apart from annoying buzz when speakers are turned right up), but after re-installing the X-Fi drivers and rebooting it's back to normal again.

I'm at a bit of a loss as to where to start trying to pin down the culprit. Any ideas, pointers and help would be mucho appreciated.

Check the memory settimgs in the BIOS for voltages and timmings, you usualy get the details from the sticker on the memory.

If you had problem a problem with sound card was the on board sound disabled in the BIOS, perhaps unistall the the Creative card and see how you go.

Hope the above helps

I'm not sure if Intel fixed it in the later core2 chips but there was a micro code update to cure behavior including random lockups including in no load situations. I had the issue with my E4300, blamed the OC but once the update was done not a since crash or lockup.

Might be worth a look
