When do you get this BSOD?
Also having more information about your hardware would be nice.
Try to disable Dual-Core mode in BIOS and see if you can get OS to boot. You can get another BSOD, but with different code, if you do that.
If this doesn't help, I'd try to take out processor from its socket, then place it back and secure it with lever to be sure all its pins are connected with contacts.
Bugcheck clearly states there is hardware problem with your CPU.
