I built myself a computer last night. Everything worked. I loaded WindowsXP Pro and everything seemed fine. I moved the comp. to my desk connected everything back up and turned it on....The fans came on, but nothing else. The hard drive doesn't spin nor the cd. I have checked all the cables, tried a minimum install and still nothing. Could the power supply be the problem? Can it power the mobo, but not the other? I have an Asus A8N-SLI deluxe, AMD 64 4000+, WD 200G hd, 1G ram, and Powercolor video card. Any help would be appreciated...Thanks
