Hey everyone, got a problem and looking for some suggestions as to what it may be.
When playing WoW (which has worked fine for over a year) I started getting a PC crash that I'll try and explain. It appears to be random, and what happens is the video feed drops (monitor light goes amber), any sound that was playing will be stuck in a repeating loop...repeating maybe the last half second of audio that was playing, and no response at all from the PC when trying to CTRL ALT DEL, ALT F4, etc. I have to either press the reset key or power cycle the box at this point. Sometimes the mouse behaves erractically a few seconds before this happens. I can move the pointer horizontally, but no vertical movement at all. This will last maybe 2-3 seconds, then it does what I explained above. It also doesn't appear to be related to WoW. I got up one morning to find the PC in this state (no video feed, no keyboard response, etc...) when I had just left it on at the desktop one night.
The CPU temp is high, at 66C full load over several hours of Prime95, but it's always been that high over the 2.5 years I've been running this box. I'm not saying CPU heat isn't the cause of the failure, I just know it's always ran this high at full load after some hours of use.
I do have this CPU OC'ed from the stock of 1.8 GHz to 2.2GHz, and it's been running that since I built it. Could a problem from OCing all of a sudden rear it's head and cause this issue?
At one point I was thinking that perhaps the GPU could be getting too hot, however, I ran a Prime95 torture test over night last night, and it failed after 7 hours and 31 minutes with a:
FATAL ERROR: Rounding was 0.49666430664 expected less than 0.4
Hardware failure detected
message. I wouldn't expect a video/GPU problem to cause this? So, unless anyone here can provide some suggestions, I'm planning on dusting the case out to hopefully rule out heat, clocking it back to the default speed of 1.8GHz, and then running memtest86 overnight and seeing what it says.
And if you specific system details are needed, they can be found here:

Thanks for any help you can provide!
