Anybody here bother fixing computer motherboards these days? I have

where the power supply took out the board, are they fixable?

I have an emachines motherboard (K8MC51G) that powers up when I push
the power button, but doesn't post of even beep an error code. Seems
to be a common problem, the PS it came with still works (tested in
another system), and there are no burn marks or capacitors bulging/
leaking that I can see. Was wondering what could be the problem (used
different CPU's, RAM, and a new 550W PS). Is there a common fix for
that model?

Are those PCI/ISA post boards on ebay useful for figuring out MB
issues?

Yes its a common repair ! *Replacing bad caps often extends the life of
a machine. *Emachines... Yuk *Look for pin holes in the bridge chip(s).

Pin holes in the plastic chip housing? So you are saying a chip blew
up and in doing so poked a hole in the casing?
