Here's the info: I rma'd my motherboard to asus, I just got it back, here's what I have now: New power Supply - 550 watts New Video Card New Motherboard New Processor NOTHING HAPPENS!! The green light on the mobo comes on, but that's it. No fans, no beeps, nothing! I have tested the power supply, it's good, all voltages are where they should be. All the power connections (24 pin, and 4 pin) are all connected correctly. The board is not in the case anymore. I wanted to make sure it wasn't shorting out on the case somewhere, so now it's on the anti-static packaging that it came in. I also removed every uneeded piece of hardware. The only things connected now are the power supply, cpu, heatsink, and fan. I get nothing. I have tried jumping the power switch pins on the motherboard, (to make sure it's not a faulty switch on the case), I get nothing. Checked all jumpers made sure they are in the right position, nothing. The strange thing is, when I remove the power supply and jump the 14 and 15 pins, the power supply fan comes on and works normally. But as soon as the power supply is plugged into the motherboard, the fan doesn't work anymore and I get nothing!! My guess is, I rma'd a bad board, and they sent me a bad board right back!! Any help would be GREATLY appreciated!!
