Built my second computer tonight and here is what happened after it was all set up.

I plugged in the power cable to the back of the PSU, flipped the switch, and all my LEDs, fans, everything kicked on fine. But I was not getting a display from my video card.

So I went to press the reset switch and the lights quickly brightened then everything shut off and won't respond. Sounds like a short somewhere.

I pulled the board out of the case and checked the standoffs first. All were screwed in, none missing and none extra. I then took the board out and called Newegg. We went through their entire testing process and they determined the PSU is working but the board is dead and offered to exchange mine free of charge. Great guys over there.

While I am relieved I can get a replacement free of charge, I am at a loss for what could have caused the short The board was not touching any part of the case, the standoffs were in, everything was plugged in properly...checked, rechecked, and checked again.

I thought maybe the backing plate for the CPU cooler. Behind the MOBO you attach a backing plate on top of the back of the CPU plate and it screws directly into the back of the MOBO, with no insulation, nut to board... However, this is exactly as CoolerMaster specified it should be installed, and I don't see why this would cause a short anyway.

The MOBO was very very close to the edges of the case when on its standoffs but it did not appear to be touching anywhere.

But I still don't know where it may have shorted out? I plan to take the computer to a local store around here and build it with them to make sure I haven't missed anything.

 
Solution


Figured out the problem.

The cpu cooler when installed put too much pressure on the socket pins and bent them. I did notice when installing the computer it seemed like I had to crank down on it, but it was set up and assembled exactly as the instructions specified.

For reference, the board was ASRock H270 Pro, with an i5-7500 Intel CPU and a CoolerMaster Evo 212 cooler. PC part picked found no compatibility issues in the build either.
