Disconnect everything from the Motherboard except
* keyboard
* mouse
* video output
* 20+4 powercable
* 4/8 pin 12v wire both coming from the powersupply,
* Cpu fan wire
* power and reset button to the case
*case speaker
Now you should have NOTHING connected to the motherboard except what was listed above.
The goal here is just to test the mobo:
If the computer still will not boot up the please remove the motherboard from the computer along with the power supply
place the motherboard on a piece of card board larger than the motherboard,
this will eliminate a short from the mobo to the case witch could be a possibility
Install the cpu with, 1 stick ram in dimm 1, power supply, case switch and case speaker
Connect ps2 mouse and keyboard along with the monitor
Repeat the above and power on
If the computer now boots into bios you most likely had a case short so make sure when installing the motherboard in the case that you use standoffs and they line up with the mounting holes in the motherboard and none of the standoffs touch anything else on the underside of the board.
Thanks to Cbarnard for these instructions

Thanks for the reply. I tried the first scenario and nothing, still no signal and no post beeps. I then took everything out and put it together on a cardboard box and I got the same result. Something interesting though, when I switched PSU's the chasis fan and CPU fan both then spun as fast as they should (where as with my other PSU they did not, but I tested both PSU's with a multimeter and they both tested correctly in terms of voltage) even with the swapped out PSU though I still got the same results (no post no signal) so I don't know if that PSU issue has any bearing. When I tried to reseat the CPU, I went to take off the heatsink but along with it the CPU came out too. I don't think this is suppose to happen, right? I inspected the MB and noticed that the CPU socket metal lever would not "click" in place, does this mean the MB is broken and won't properly hold the CPU and thus that being my problem? I'm gonna try to RMA the MB to ASUS but I'm not sure if they'll accept it since they claim not to replace broken hardware (even though it was shipped that way )

If that is indeed the case then the MOBO would be defective and ASUS should replace it for you. I suggest you do call ASUS and talk to them and let them know that this is the way it was shipped by them and received by you. If the CPU seats properly then the pin issue should not be the problem. Please keep me informed as to what they say and what happens.
