New computer...wont start up :(

[dmahat]

Hey guys. I just ordered parts for my new comp and the thing wont turn on. I have built numerous computers so i know what im doing...but this one seems tricky. Ive already had a replacement motherboard come in, tried that out, and still the same problem. When i hit the power button, the side fan turns on for a second and then nothing. The light on the mobo turns on, but i guess no juice. I stuck in another psu and nothing. I also bypassed the front power switch and nothing. Any help would be greatly appreciated! thanks in advance.

The heatsink is attached correctly to the CPU? Is the pc giving you any beep codes?

This happened to me before on my most current build. Try taking all the connections out. Make sure you are grounded and reattach them all...making sure they all get pushed in tight and snug. If that doesnt work, make sure all the little wires from the fans and whatnot dont touch any other wires..you possibley are shorting out something. I think I solved me prob this way. See if that works.

First of all a list of your system components would be helpful.

Have you tried to set up the system outside the case. This will help to rule out any possible grounding issues in the case. As mentioned before double check all your connections. Yes i 'm sure you know and have done all this already just want to cover all the basics. Aslo tyr starting the system on the very basics. With only 1 DIMM and no drives connected.
