- Homebuilt PC doesn't boot

My homebuilt, old (SOYO 6BA IV) box stopped booting. The light on mobo
is on, but when I push ON button the fans (CPU and case) get very short
twitch and everything remains silent and still. No humming, nothing.
I brought another ATX PS and the effect is exactly the same, so I guess
it's something else.
Suggestions, please? (OK, I know I should upgrade mobo anyway, but
spare me that one this time... ;))
Re: Homebuilt PC doesn't boot
You quite sure you aint one of those rocket scientist fellas ?
Most likely something is loading the PS too much, so it comes up
briefly, decides that the load is too high, and shuts down immediately.
Its most likely what has failed. Unplug all the drives and
cards to check if its one of those thats shutting the PS down.
Check the caps on the motherboard. Those are the usually blue or
black plastic covered post like things that stick up vertically from the
motherboard surface. The tops should be flat. If any have bulged or
are leaking, thats a failed cap. You need to replace the motherboard.
If it looks like you need a new motherboard, before you swap it, run
the motherboard loose on the desktop to check for a short to case.
