Motherboard grounding/power problem

Hi, I had a old homebuilt which had power problems. Since then I have replaced the PSU, motherboard and the RAM and I'm still having power problems.

After consulting with some friends, the most likely explanation is the improper grounding of the motherboard or some wiring problem.

I have recorded a video which you can view right here:

As you can see there's the CPU startup sound, and the cooler fan moves a little bit but the power is quickly cut off. It seems like the computer keep trying to boot but with the same result.

Also I noticed a weird standoff in the case. Now I'm not very familiar with motherboards but can anyone tell me what this is:

It's the bronze color standoff in between the two RAM slots.

Thanks alot.

  1. The bronze stand-off is a ground and normal.

    You should work thru the troubleshooting guide at the link below. It could be something very simple like a 12v power cable missing to the mobo or Vid card.
