Is my motherboard the problem?

My computers fans turn on for half a second along with the front light, but then they turn off. This is a brand new computer, and I've never been able to POST.

I followed all the steps here to no success:

I did the paper clip test to see if my psu was the problem, and the fan ran in it. I also tried another psu on the set up, and it did the same thing.

Specs:
--CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133
--OCZ ModXStream Pro 600W
--GIGABYTE GA-H77-DS3H LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
--Intel Core i5-2310 Sandy Bridge 2.9GHz (3.2GHz Turbo Boost) LGA 1155 95W
--SAPPHIRE Radeon HD 7850 2GB 256-bit

Do you have the correct connection to the video card from the power supply? I would also try the breadboard test out of the case using onboard video. For beep codes, connect the front case speaker if yours has one. Breadboarding is a generic term for testing the board on any non conductive surface such as wood or cardboard.

It's the 24-pin ATX power connector on the motherboard beside your RAM on the right edge of the motherboard. Also, make sure you have the 4-pin CPU power connector connected, it's beside your VGA and DVI ports in the top left corner of the motherboard.

It those basic checkpoints for hardware configuration don't fix the problem, you can unplug all power connection and reconnect them after hours .. just try to get into bios, check the bios version and give it the latest update, if it is some cold boot issue, it should be known with solution.

If it is powering on then off, (not continuously) then you are probably not grounded properly, did u put the standoffs under the mb?


Had all seven of the standoffs on.

It's possible the motherboard was defective from the factory. Have you made any progress on this since your last post snowboard? Or has the situation changed at all?

i had another psu in my room from my friend, not a full pc.

Anyways, i decided to just send the motherboard back for replacement after the same thing happened with just the mobo, the psu, and the cpu/fan together. Hopefully it's not the cpu that is broken, but i didn't have anything to test with.

I dont think its cpu. Sometimes it happen from bad power line. I had similar issue like you. I replace my psu and use good electric line. Problem solve.

But you already try with another psu. This is confusing.
