Random windows 7 x64 locking up :(

[roozor]

I have been having random freezes/hangs in windows 7 with no BSOD. It's completely at random it could happen within 5 mins of using the machine or 5 hours.

I've tried disabling bits of hardware i don't use. (on board sound, on board lan, on board gfx) still no joy.

It's an Overclockers Arkham Destructor Intel Core i5 2500K 3.30GHz @ 4.40GHz DDR3 Limited Edition System

I've installed windows 7 64bit ultimate (legit copy) and a Belkin firewire pci card. Apart from that it's exactly how they sent it to me.

Any help appreciated. When the system doesn't crash it is awesome!

Ran cpu bunintest which tested everything at once for 15 mins. No fails or errors.

Just been looking at the windows event logger from last night as it crashed after i went to bed about 12:30. At the time it crashed, only a few warnings about websites not being able to reach dns servers. No critical errors or anything interesting.

Also last night i ran it with stock speeds, unplugged anything usb not needed and even disconnected my firewire card. Still froze.

I'm truly stumped :/
