    What did you unplug? Check any aux power connectors, fan connector, SATA cables. If you used any tools, check for scratches/gouges on the board.

    Re: CPU running dangerously hot

    Didnt unplug anything, just unclipped and removed the heatsink and processors then refitted them, already checked all the sata connections and all the fans are running. Only tool I used was a screwdriver on the fan mount for the heatsink to unscrew something, dont really think I could have done any damage there. I guess the only logical conclusion is that I somehow damaged the motherboard but other than static discharge (which I think is unlikely) I dont really see how I could have done.
    Looks like Ill have to chuck out yet another motherboard.

    Check the corners of your CPU to see if you've chipped the die when you reinstalled the heatsink. Does the mobo beep when you boot it up, if so depending on what BIOS you have you can usually figure out what the beeps mean.

    Try booting up with all your drives unplugged (Harddrive, DVD), any extra fans (obviously leave the CPU fan plugged in), soundcard and gfx card (leave the gfx card in if you don't have onboard gfx on your mobo). Try also taking out all but one RAM module if you have more than one installed (leave one in DIMM0). If you have two, try rotating them to see if they're damaged.

    Re: CPU running dangerously hot

    Try re-seating your memory modules. Use the clips at either end to lever them out, then put them back in place. If you have a lot of dust, get some 'canned air' to blow it out of the components.
    When you did all your cleanup, did you have the switch on the back of the computer set to off? Or the power cord unplugged? Some power supplies still produce some power, mostly to 'wake on lan' ethernet cards, and keep things somewhat alive even though the machine is powered down. I would also look to see that the cables that plug into the motherboard are all pressed in place.
