I'm not sure if I have a mobo problem or a PSU problem. When I turn the computer on, I get nothing. No fans, HDD doesn't turn on, nothing. I get lights but that's it. On occassion, if i turn it on and off enough, it will turn on correctly, however within 10 seconds it completely shuts down. Not sure how old the computer is since it belongs to a friend of mine, and it appears as if it was custom built. When it does happen to completely turn on, all fans come on, video comes on, WinXP starts up, ethernet lights come on. Not quite sure what to do with this. Any help would be awesome! Thanks guys!
