P5Q SE won't boot up at all

[Torsitano]

I just received some new parts from newegg. I got a ASUS P5Q SE mobo, 4 GB of corsair DDR2 800 RAM, and a Core 2 Duo E7300.

I installed everything without a hitch. But now that I finally tried starting it up, I get absolutely nothing. No fans, no HD, no lights, nothing. The mobo has this neat little green LED near the bottom, that supposedly when the mobo is receiving power, it will blink. I was getting no blinking with my 500w power supply that was in my previous computer. So I assumed it to be a PSU issue. So I went and grabbed another PSU. Now I'm getting the green blinking light, but my computer still refuses to start up when I press the button. I have checked the wire for the power button several times, and I'm sure it's plugged in to the right pins. I tried reseting the CMOS, I removed all hardware besides what is absolutely required, I have tried different RAM configurations, I have tried different PSU's. I'm all out of ideas. You have any?

May be your BIOS and your CPU.. the 7xxx series chips are tricky with the new P5Q boards/ASUS BIOS's, I would try a diff CPU and flash the BIOS to a new one (assuming it will boot with the different CPU) and put in your 7300 and see if it boots then. I know that CyberDruid had that same problem with his ASUS Blitz and what I stated above was his solution. Try that and get back here to tell us what happened....

I actually already RMAed it. I should get the new one on Tuesday. I would have tried a different CPU, but the 7300 was the only LGA775 that I have access to.
