Bad Mobo? How to troubleshoot?

I have a homebuilt pc in my garage, with a soyo k7vempro motherboard,
running windows xp. It is a pretty lean machine, with only Sonar
recording software and 2 or 3 other apps installed. (my garage is also
my music studio)

Anyway, sometime this past winter it developed 2 simultaneous

1) It only starts once every so often - I changed power supplies from a
working pc, and replaced the switch in the case (the old one was crappy
anyway), still no change. I can click and click, and it only starts
once out of every bazillion or so clicks. -- once it does start, it
seems to run fine - it has been on now for weeks, for fear of being
unable to turn it back on once it is powered down.

2) It does not shut down all the way - this may be the major tell here
(?) of what is wrong... win xp will shut down, and just about the point
that it used to just peacefully click off, it instead now goes into
this strange idle, black screen, fans running, and the led's on the 2
cd drives flickering sickly on an off.

AND now I have one more fun problem... it stopped seeing the onboard
LAN port. No "network adapters" category is visible at all under the
device manager, and there is just nothin' happening lan-wise

I have NO problem replacing the mobo, not a big deal to toss this one
and start over, but I need to know if it IS in fact un recoverable, and
that a new one would do the trick. More than the cost, it is the effort
to rebuild the darn thing that has me hesitant.

Thanks in advance for any advice...

Re: Bad Mobo? How to troubleshoot?

Check inside the case for anything that looks like it could be
shorting the mobo out... A wire touching something it shouldnt be,
check the clearance between the board and the case, etc... I wouldn't
think that would be the problem with shutdown mind you, but thats what
it sounds like it could be since its not powering on even with a
new/different PSU and switch. Good Luck :)
