help hardware question

[hanfamily at earthlink.net]

Hi All,
Last night my husband left his computer on during a storm. For some
reason it didn't trip the surge controll when the power went down.
Now it does not come up at all the cd and hardrive lights and the
fan works. I don't get any boot not even bios. The monitor is still
good as I switched it, so is the modem. Any ideas where to start
to figure out what happened? (Not that it matters for this but
it runs rh7.3 and is my gateway)
                         Thanks
                         Linda
