The joys of doing it yourself. I just installeda p4 3.0 processor with a thermalright SP-94 heatsink + thermaltek fan without problems. After replacing and replugging everything in I couldn't get power to run when I pressed the start button my case. I checked my motherboard (a p4c800-e deluxe asus board) and my integrated lan orange leds display as well as the motherboards green led when I have my power supply switch set to - on. Other than that I can't seem to get any signs of power running through even though I have my atx power correctly inserted into the pins as well as my restart button. I've tried disconnecting and reconnecting numerous things and made sure my processor was installed correctly 3x already. I've also reseated my old processor and had the same problem. I don't think anything is burned out as I'm receiving lights and most of my hardware is brand new (corsair 512 ram x2, 500watt powersupply (brand new), fireball harddrive 12gb and a 120gb maxtor 7200) I've also disconnected everything but the power (+) (-) to see if I could get just a few things to boot up and was unsuccessful. I've never dealt with the problem of just getting my computer to even receive power so I'm clueless as to what else I can do. Any suggestions would be greatly appreciated.
