EVGA x58. Installed new HSF now no post code :(

king awesome

I have an EVGA x58 SLI mobo and an I7 920 cpu. My cpu was running a little hot when gaming so I ordered a cooler master V8 to cool her down and for possible overclocking in the future.

I installed it and now when I boot up, no beeps, no post codes, nothing. The leds on the board light up and all the fans kick on but that's it.

I took everything out of the board and took the baord out and sat it on a wooden table. Right now the only things connected to the mobo are the CPU, 3 ramsticks and the 2 power cables. I still get nothing when I turn it on. I unplugged the 8pin power connecter (the cpu power) just to see if that would do anything, and that gave me the FF post code (FF = 'booting') and then just hangs there.

So... CPU, PSU, or Mobo. Which one did I destroy? Also, what could I have done to break one? Additionally, is there anything else I can do to test this stuff or maybe I'm missing something glaringly obvious and I'm somehow not screwed.

Thanks
