I've recently upgraded my old Athlon 64 X2 based system with the following components:
Core 2 Quad Q6600 G0
Gigabyte G33M-DS2R motherboard
4x2GB Corsair XMS2 RAM
I've had the system up and running for about a week, running overclocked to 3GHz. It passed Orthos and Memtest fine at these speeds. In the last few days, my machine has kept on occasionally locking up. When I looked at my system temperatures, everthing seemed fine except for the graphics card which seemed to be massively overheating. Thinking this was the problem I've removed the card and gone to onboard graphics, but I'm still getting the lockups. The same problem occurs at the stock 2.4GHz and I've even underclocked to 1.2GHz (6x200) and still the lockups happen. The only disturbing thing I can find is that the processors VID is 1.325 but CPUZ is reporting it as being way below that. I have a decent power supply (Seasonic S12-II 500W) so I don't think this is the problem. I've also tried running a prime burn in test off a bootable CD in case the windows install has somehow become corrupted - the system hung after about 5 minutes. I also occasionally get lockups in the BIOS after immediately resetting the PC when this happens.
I've attached a CPUZ / Coretemp screenshot in case it helps. I'm completely at a loss as to what the problem is, so any advice would be greatly appreciated.
