Intermittent sound/video problems

| Hello all. Just wondering if anyone has any ideas I don't have as yet.
Some time ago, I installed a new motherboard on a friends Compaq computer.
It's an older system, and as I do not have it in front of me now, I don't
have the model number on hand. In any case, the system was originally
shutting down at random, and after changing out the other likely culprits
(memory, even the power supply) I decided to try another board direct from
Compaq as everything else was integrated. After this, I ran the system all
night long, and it remained stable.
Several days after returning it, however, she reported that at times she was
getting no sound. Also, at times, the picture on the monitor would begin to
jump wildly. Note that I reused the parts from the original setup (cpu,
ram, etc.) in the rebuild. It is an old machine, I believe running a K6
AMD, and almost everything is integrated into the board itself.
My current thought is that the new board might be shorting some place, maybe
even making slight contact with the mounting plate. I was wondering if
anyone had any other avenues worthy of exploration? Until I get the
computer back from her, I won't know much more, but I wanted to be armed
with a few more probably causes than this.
Thanks.

Cripes, how much did Compaq screw you out of for the replacement mobo?
More than $200?

Sounds like Compaq sent you a bad motherboard. No surprise there. Good
luck getting another one.... Seriously, you said it was a K6? I just
sold a used system (box only) with a K6/2-500 CPU, 128MB, a real 56k
modem, a real sound card and a real video card for $100. You're working
with trash. The thing to do is: get your money back from Compaq then
build her real system. You can get a new ATX case for $40, a new
'All-in-one' mobo for $65, a 256MB DDR DIMM for $40 and an Athlon 1700+
for $52. Probably less than your friend paid for the work you've already
done. And, it would be 20 times faster. And, no more random shutdowns.
And, good luck getting your money back from Compaq.
