A friends HP xt963 computer turns on (fans spin), but the monitor doesn't get a signal. The monitor works. I tested it. I put in a old but working pci video card and the monitor still doesn't get a signal. I don't see a jumper to clear the cmos anywhere, so I have took the battery out and plan to leave it out for 24hours to clear the cmos. My guess is either the cpu or MB died. Probly the MB since I don't think cpu's die that often. I cannot test the MB or cpu since I don't have anything that will run a celeron 1.2ghz or a cpu to put in the 810e MB. Is there anything else I should try?
