[QUOTE="jamesh2k, post: 1605033, member: 333168"] Hi, I have motherboard that is doing my head in, it just randomly stopped working and when reading the pins the voltage is going 16.5 to 0 back and forth so I must have a short to ground somewhere. The 3.3v rail is fine 5.5 unknown as does not power on. I cant get a solid 12v to power on the mobo, I found a few chips getting warm so removed them both for testing but still going 16.5 0. Any ideas? anyone got the schem? [/QUOTE]
