Hello here are the spec's of what I am working with: asus p4p800-e deluxe intel 3.2e prescott 1gb 2x512mb kingmax ddr400 maxtor sata 120 gb hd sony floppy dd hiro 56k internal modem chanitech geforce fx5200 envision eft720 flatscreen crt Okay here is how I saw it happen. hooked all this stuff up turned it on and it worked. Got past the bios screen and to a black screen no os detected. Shut her down and came back a little while later 15 minutes or so. I wanted to set up the bios. Got to the screen for setting up the hd, and wham she went dead. Started disconnecting things one by one. And trying to power up no luck fans turn about one revolution. Everything is out except the cpu which I did pull and try a power up same results. Tried the thing about pulling the switch leads and doing a direct power up. same thing, my guess is a dead board or the psu. Any help with this would be greatly recieved.
