    First post here.

    Basis of my problem.

    -Dad was fixing some electrical powerpoints in the house and needed to switch off the main power supply.
    -Computer was on, lost power once main supply was off.
    -After he was done and main power was back on, i press power button on comp, starts up, then a few seconds later it shuts down again.

    My first thought was that the PSU is dead and tried placing an old one from an older computer to see if that boots it up properly.
    No luck, same problem occurs.

    My motherboard is a Gigabyte, Model: GA-8VM800PMD-775-RH

    I even tried clearing the CMOS, following instructions from the Motherboard manual.

    Any ideas as to whats actually wrong with it, and what i need to fix it?

    Wait so basically, you are saying that your computer wont work?

    It might not be a problem with your motherboard, probably something else

    is it the actual pc, are you sure, because it may be that the PSU is trying to draw power from the mains, and somewhere along the line and fuse is tripping and dropping your power?
    Test your psu, see if it boots on its own, get a paper clip and bend it so its like a pair of tweezers, then put one end into the green wire of the 20(4) pin atx plug, and another in the black wire next to it, this should boot your Powerpack, if this runs ok then its time to inspect your motherboard
