    Under the circumstances I would'nt be concered at the present for cleaning the old compound off to test for P.O.S.T. If it works replace the compound before using though.
    POST! Thank you very much for your advice.

    I added the other components back in and I can see the PC starting to boot the OS install CD. I'll stop it there for the moment, until I replace the thermal compound. But I'm feeling a lot happier now. :)

    GREAT! Dual Bios! I use 90% rubbing alcohol to remove the old compound. Clean well and don't forget to check the bios update. You should download and flash to the latest Bios if it is'nt already. Scroll down here to download----> GIGABYTE - Support&Download - Motherboard - BIOS - GA-MA770T-UD3P (rev. 1.0)
    Do not use @Bios. Here is a great bios flashing tutorial for Gigabyte boards from Lsdmeasap. You will want to use it. http://forums.tweaktown.com/f69/bios...h-guide-27576/ Here are some of the updated drivers. Scroll down and select your OS---->http://www.gigabyte.us/Support/Mothe...ProductID=3096

    CMOS Jumped while powered on should not harm anything, just letting you guys know in case you had narrowed this down to be the cause of something.

    This is good to know. Thanks for the tip. I was'nt aware of this. I never tried it. The motherboard manual says.
    • Always turn off your computer and unplug the power cord from the power outlet before
    clearing the CMOS values.
    • After clearing the CMOS values and before turning on your computer, be sure to remove
    the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.
    • After system restart, go to BIOS Setup to load factory defaults (select Load Optimized
    Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for
    BIOS configurations).
    It does'nt say it will cause damage to the motherboard, just that it MAY cause damage.

    Yes, it is advised to not have the system running of course! But no harm will be done, but that of course does not mean that it couldn't cause harm though I am just saying I have never seen it.

    Normally if the CMOS jumper is on the pins when you power the board up it will fail to start, and if you put one on while it is running it will either shut down then, or shut down instantly when you remove the short.

    Not advised to do of course, but in my experiences has not ever caused any harm
