Voltages for a Intel G860 Processor? Trying to figure out the lock ups.

I RMA'd my old EVGA 680i SLI board a couple months ago because the PCI-E slot went bad after having it for 5 years.

They sent me a EVGA P67 SLI board as a replacement. I had to buy a new CPU and Ram since the socket was different and it is a DDR 3 board. The processor is the Intel G860 Pentium Dual Core processor and the ram is from G-Skill. I have 8 GBs of 1066 Rip jaw DDR 3 ram at factory timings.

My computer seems to be locking up at random times, mainly when I am gaming, and sometimes when I am just browsing the internet. Last night the computer locked up while I was on Facebook reading a status with comments. I left it alone for an hour and when I came back, the page had updated and there was a different status from someone else up instead of the one that I was reading. So something happened. When it locks up I am unable to ctrl-alt-del and am forced to reset the computer.

The voltages coming from the power supply are pretty stable, I tried a different video card and ran Memtest 86+ all night last night with no errors. The voltage to the CPU and ram is set to auto in BIOS.

I am wondering if maybe there isn't enough voltage going to the CPU causing the lockups. So I am curious as to what the recommended voltage is for that CPU. I looked for that information, but haven't been able to find it.

I was also wondering if it could be my wireless mouse and keyboard causing the computer to lockup. I can understand that if there is a problem with the mouse and keyboard it can give the appearance that the computer is locked up, however the last time it locked up I was playing WoW and my character froze in mid run. So I am not completely sure if it's the keyboard and mouse.

Temps aren't an issue. I keep track of them using Aida64 and MSI Afterburner.

Any help will be greatly appreciated.
