Setup: P4P800-VM Mobo (Using on board vid) P4 2.6Ghz HT Tech 512 MB RAM 350W PSU CPU Fan spinning, CD Drive lighting up, hard drive humming, monitor still in sleep mode/black sreen. I've tried alot of things. No shorts to the mother board due to case, I took out the mother board and placed on peice of cardboard and still same thing. Resetted the CMOS using the jumper on mobo. Took battery out, tired that way, took batt out and flicked power 20 times and put batt back in, no luck. disconnected everything (fans, cdrom, HD, extra memory) not needed to boot at least to bios and no luck. Monitor works, tried with my laptop. I'm out of idea's. Any help plz?
