Could be power supply or even mobo components going out. I've had similar happen where some board component went out first, then eventually board died completely. Power supply is easy enough to check if you have a spare.

It is a P4 3400, Intel 850Perl, 3GB of Crucial DDR, All in Wonder 9600 PRO, a Promise ULTRA 133 PCI, one Maxtor SATA, three WD PATA, a 8 speed LITON DVD burner, powered by a Antec 550 True Power. Old stuff put together for a single purpose... works well, until last night. I was running it with the TV on and all of a sudden, without any indication of a problem, the TV audio and video just blanked out. The computer was still powered on but nothing on the screen. First I powered off at the cord, waited a bit and then powered up again. Nothing appeared on the screen. Tried this numerous times after checking cable connections. Then I hooked up my laptop to the VGA cable... the monitor worked. Then, leaving the AGP AIW 9600 PRO in place I put a known working Matrox PCI G450. Still no video appears... even at POST. But it will boot up to XP PRO and I can access all the hard drives across the network. Just no video It is very strange but I am thinking PS. The Antec True Power is problematic and the problem is a strange one, as are most PS problems. I put a meter on a powered up molex and got 5 on the red and 11.94 on the yellow. Any thoughts?
