VERY puzzling question!

Well, what I decided to do it just get a whole new case, rip the dang thing
apart and rebuild it from scratch putting one card in at a time, run it for
a day or 2, put another card in, run that for a day or 2 until I find
what's wrong. What I don't understand is that I've replaced EVERYTHING
that could be the cause except MAYBE the case. I've built several systems
and have never had this much of a problem, EVER. Maybe some of the parts
came from near the Bermuda Triangle or something....
Regardless, I really do appreciate everyone's input and time with this and
will keep you all posted when I find the problem. It's probably something
really simple, like a loose screw on the ground from the board to the case
or something. Who knows......

Thanks much group!!

That's exactly what I did, build a whole new computer, before I found it
was an intermittent AC outlet (in the power strip in my case).

Did you check the power mains like I suggested earlier? Which, btw, means
the power cord too.
 
Yes, and actually, the guy I sold it too, I told him he should have a
dedicated circuit and a UPS to be on the safe side. While I was ordering
some parts during this escapade, he called an electrician friend of his and
had a circuit put in and went to Best Buy and got a UPS for it. I replaced
the cord as one of the 1st things actually. I swear, I think I have done
every conceavable thing to remedy this problem and I just think this PC is
hexed... I don't normally believe in this sort of thing but..........

I once had a computer that ran GREAT when the side panel was off, but when
you put the cover on, it would short out, reset the system, and had many
many BSD's if the cover was left on. That was another puzzling one. I
swapped the case and BINGO, no more problems.
I'm plum out of idea's other than to do the same thing, Get a new case and
start the build from scratch. AND, come to think of it, the case I used
might have been the same type, was a cheap one from a local PC store here, I
bought like of them for real cheap, near $25 a piece and as people upgrade,
I"m starting to get a couple of these cases back now.
If it is that case, what could possibly cause it to malfunction as it does??
The case merely provides a ground doesn't it?

Anyway, thanx once again for the input, I'm off to www.Newegg.com

Bummer. It sure sounded similar to the problem I had (dern near went insane
on that one). The dedicated circuit and UPS is a good idea regardless, though.

There's not a lot a case can do to cause this kind of problem. About the
only thing I can think of is if it's one with built in 'bumps' for the
motherboard standoffs and if one is in the wrong place it could touch the
underside, causing a short. Which could also be intermittent or happen only
when something flexes the case a certain way, like securing the side panel.

Of course, the same thing could happen if you inadvertently install a metal
standoff in the wrong hole and just don't realize it.

It can also be a problem if you use screws with too large a head that
overlaps into the circuit area.
