My new build won't even post after I've put it all together. I push the power button and get absolutely nothing.

I did get the fans to spin one time. There was no RAM or hard drives plugged in. Once I plugged in a stick of RAM it wouldn't start again. I took out the RAM and it still would not start. Right now no matter what I plug in or take out, it does not work.

These are my specs:


The Sandy Bridge i3 2120

Cooler Master Elite 371 Case

I've tried an Ultra 450W Power supply (http://www.compusa.com/applications/SearchTools/item-de...) and a Thermaltake 430W PSU which I got from Best Buy because I suspected the psu was the problem.

BIOSTAR H61MGC Intel H61 Motherboard

1 stick of 4GB Visiontek RAM - 240 Pin

I'm reusing a 200GB Seagate Hard Drive from an old laptop

XFX HD-677X-ZNLC Radeon HD 6770 Video Card

Stock CPU Cooler

Things I've already tried:

First, I did absolutely everything in this thread: . Nothing worked.

Swapping the PSU. I've tried both Ultra 450W Power supply (http://www.compusa.com/applications/SearchTools/item-de...) and a Thermaltake 430W PSU which I got from Best Buy because I suspected the psu was the problem. This resulted in no change. I know it's a possibility that I just recieved two dead power supplies so when I go to return the Best Buy one I'll buy a new one.

I might try a power supply with a lower wattage. Could somebody please help me? I'll post pictures if necessary.

Also: I'm sure that nothing is shorting the motherboard because I tried breadboarding it on top of some styrofoam.
Thanks.

check that the i\o shield not shorting out the mb.
make sure the 24 pin and the 4/8 pin atx plug in connected.
it be near the cpu or one edge of the mb.

I tried breadboarding it on styrofoam so I'm sure nothing is shorting out the motherboard. Both the 24 and 4 pin atx plugs are connected.

This: http://www.compusa.com/applications/SearchTools/item-details.asp?EdpNo=1636640 is my RAM. I don't think that the ram is the problem though because I would hear a beep code at least. It should still work without ram installed. I checked the cpu as best as I could, it looks like there are no bent pins.

You should make sure you didn't short the motherboard itself.
