I'm assembling a new system and having power issues. When connected and the switch on the power supply is on, all my components receive power before I press the power switch. Fans turn, DVD drive spins and opens, yet I am not able to power up my computer. I stripped everything down to just the motherboard, CPU and RAM and I still get nothing. No POST beep or anything signaling a startup taking place. I am wondering if this could be caused by a faulty power supply (ie a short inside the power supply) or more likely by a short in the case somewhere. Any help in resolving this would be appreciated!
