My previous computer setup was: motherboard(P5NSLI), processor(Intel Core 2 2.4), video card(7950 GTX), 550 watt power supply, 2 CD drives, 1 floppy. I purchased a new case that came with a 1000 watt power supply, and also a zalman cpu fan. I transferred everything over to the new case. Swapped out the 550 power supply with the 1000, and changed out the cpu heat sink with the zalman cpu fan/heat sink. After everything was setup I pressed the power button and nothing comes up on the screen. The slave CD drive has a green led that stays on, and neither one will open when I press eject. All of the fans attached to the motherboard function. The motherboard’s led is on. I hooked everything back up the way it once was and I still have the same result. When I detach the PATA cable from the CD drives they both eject when pressed. I am thinking that the power supply may have messed up my processor or motherboard, but I’m not sure. Even if the processor is not installed won’t the screen still load up and go into the BIOS? Any help would be appreciated.
