Having trouble with my friends build

[bvsbutthd101]

Specs:
Mobo: Newegg.com - GIGABYTE GA-H55M-UD2H LGA 1156 Intel H55 HDMI Micro ATX Intel Motherboard
RAM: Newegg.com - A-DATA 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model AD3U1333B2G9-DRH
EVGA GTX 470
Coolermaster 700w psu Newegg.com - COOLER MASTER eXtreme Power Plus RS700-PCAAE3-US 700W ATX 12V v2.3 Active PFC Power Supply
and i5 760

Now when I go to turn the computer on it just shuts off right away and keeps surging on and off. But when I take the graphics card out it turns on fine. I know it's not the gpu cause i tried it in my computer, worked fine. I also tried putting my 260 in his system just in case he didn't have enough power for the gtx 470, still did the same thing.
Now I was thinking the motherboard is bad. Is that possible?

Have you tried both PCIe slots? What CPU is he using?

Possible short with the case. Take everything out, and re-assemble on the board's box.

yes I've tried using both pci slots, but when I put the card in the other slot, it turns on but I get no post.

i tried each slot, tried each ram stick individually, still same problem. I don't understand why the computer stays on when the GPU is not in but turns off and on while it's in.

Gigabyte boards do that, the board is thinking that there's something wrong with the BIOS that's preventing it from posting, so it keeps trying different settings for you to see if it will post. It's actually quite annoying and detrimental if you don't know what the board is doing. I would recommend plugging in a motherboard speaker and listening for beep codes, those make life a lot easier with these Taiwanese design motherboards.

leave it do its thing, first bios looks corrupted from what i see now. might take a few minutes.

shut down with the button. pull the plug. push the power button. plug back in..wait...push the button...let it cycle.

if it is a corrupt bios the second one will kick in, just let it be. :)

if its not, then its not.

like how long, i let it turn off and on for like a min or 2
