Help, I don't know what the problem is!

I have been having a very bazare problem with my pc,
so here goes:

Hello, I had been running this setup for a month after upgrading due to the pc not working.
Now I took the motherboard into the shop I purchased it from as I have been having problems.
They tested it with their own cpu and ram. I have taken it to them several times.
They said it was fine...

So I took the motherboard home.
I put my own amd x2 7750 and 2gb of ram, gtx 260, my 250gb sata hdd, 2 dvd drives, usb ports,
onboard audio and the front panel connectors and fan as well as spdif.

It worked first go, so I turned it off after about 1 hour of use.
I turn it on later and nothing.

I take everything off except cpu and ram and 24 pin motherboard connector and 4 pin atx plug (the one
near the cpu).

Still nothing.

So I get my original processor that the board originally stopped working with and put it on the board.
The board works first go.

It seems as if the board builds up a negativity with a processor, so when you change it.
It will work, as it did for the shop.

So I will see if the original processor (the one that originally stopped working) stops working like
the new one.

Thanks for your time.

P.S. I have tested this with 3 different power supplies, different ram and that is all is being used on the board

  1. A basic answers to start the process with.

    Bios Update for the motherboard?
  2. Thanks for the quick reply!

    The bios I am currently using is the most recent one.
    I was using the original bios that came with the board when the original problem started. And when I took the board into the shop it was flashed to the most recent bios while in the shop.

    The board is a gigabyte m78-sm-s2h.
    The processors:
    x2 6000
    and x2 7750.
    The power supply, huntkey titan 650w.
    And I have tested it with 2 other power supplies that I know work.
    And same for the ram.

    The x2 6000 stopped working randomly after I upgraded the graphics card (zotac gtx 260 (216 core) and power supply (huntkey titan 650w) (I had used the new upgrades for about 1 month though after upgrading).

    x2 6000 stops working with the board

    Then the x2 7750 was used for a little while,
    then does same thing as x2 6000.

    Now x2 6000 works and x2 7750 stopped working.

    Sorry for long reply, I just wanted to make post more clear.
  3. Take the motherboard out of the case and put it on a non-conductive surface, it could be shorting out on the case.
  4. Thanks for the thought but I have already tried that (and
    done everything I said above).

    I don't think the case is the problem,
    it's a coolermaster rc 690.
