Hi, i just recently changed CPU and its causing some really strange behaviour. I originally had a Pentium D 820 but i replaced it with a Core2 Quad Q8200 and the bios doesnt agree with my decision. I can run the pentium day and night with no issues but with the Core2 in there's almost like a 20 second timer from power on until everything freezes.
*bios stops responding
*cant even get to boot because the bios freezes after checking DMI data
*cant enable failsafe bios defaults, just opening that menu will freeze it
It's a GA-G33M-DS2R and Gigabyte's website specifically says the Q8200 is supported with my current bios revision.
Eveything just hangs, wont accept any keyboard input and the bios clock stops dead. I noticed that if theres a cursor or a Y/N prompt onscreen it will keep flashing no matter what.
I've reset the cmos battery, ive disconnected the power and left it for a bit, i checked that the CPU isnt overheating and dying mid POST, checked the CPU wattage was within the limits of my old psu and MB. I dont have any other ideas.
Like i said i can be stuck at the bios watching the internal clock get stuck at 12:00:53 for 10 minutes then shut it all down and put the pentium back in and i'm straight through POST into windows.
Any help would be appreciated
Edit: sorry if this doesnt belong in the hardware section
