Black screen on boot up

[phalanx]

Today i was installing a V8 and a new SATA DVD drive into my machine. I unplugged the PSU, than removed the old heatsink and used thermal paste removal solution on the processor. I installed the V8 with some issues, the X bracket wouldn't go on properly and i applied a little pressure to try and get it to mount right, to find a small piece to be poking up to hinder its install. So i drilled a hole into the X bracket and completed installation. I than installed the SATA DVD drive with no problem. I turned on the computer only to find that the computer would turn on to a black screen. At first i thought it was my video cards reinstalling because i had removed one, i listened for about five minutes for the Windows start up noise, no sound. All the fans and the hard drive would run and the mother board light was on, the CPU light would illuminate solid for about five seconds and than go off and stay off. Thinking it was not enough power going to the computer i unplugged the heatsink fan and tried again, with the same result. Looking for some help!
