this aint good

Ive been running the rig in my sig for about 4 months now.
I ran it today for a few hours no problem.

It has decided to explode

Boot up into windows and start up bf1942- hard lockup
Reboot
Asus gives me the "falure due to cpu overclock message"
So, Everything goes stock
And
Same thing, gets to windows then hard lock
Reboot
Now, it hard locks in bios

Im afraid it may be death by volts for my trusty tbred
But,
Anything else it could be maybe???

doesnt sound good, how much vcore were you feeding her? even at everything at defualt you still get locks? if you can get another chip to test id start there.
