Hardware Problem?

This is apparently a hardware problem but thought there'd be some pretty
good
ideas of the problem here. No power, no lights, no fan action, no HD
noise... nothing at all.
Checked swith for continuity - ok
Checked power supply in another computer - ok
Tried another power supply in this computer - still nothing.

Suspect bad component on motherboard. Is there anything specific I could
look
for on the botherboard? Perhaps replacing the motherboard would be best
idea?

Motherboard is K7 - M810XLM, Socket 462

Sounds to me like the switch itself is bad. If the power supply is
good, the fan would kick on with the power even if the computer is
otherwise bad. And you'd see an indicator light at least flash when
you turned on the PC.

But your test showed that the power supply is good. And even more,
you hooked a known good power supply into this computer and it
doesn't function. That argues pretty strongly that power s not
reaching the power supply. Check the switch, the power cord, and of
course the outlet.

I can't see any reason even to think about replacing the MB. If the
fan and lights aren't on, the power supply isn't supplying power.
 
Have you tried another ac outlet? Do you have multiple outlet box with
switch? Plug in a lamp to check.
 
I once had a case where the reset switch was faulty and essentially stuck on
so that when the computer was powered up it was as thought the reset switch
was continuously depressed. Try unplugging the reset switch from the mother
board or both reset and power switch and then simply short the 2 pins which
the power switch plugs into. You use a small screw driver to short the pins
by simply allowing the two pins to briefly be connected.
 
Must be my lucky day. Yep, the machine has been tried from several
different
outlets, two different homes... etc. But my luck is that I happened to
have another
old computer and its motherboard has the same CPU socket. I replaced the MB
in the non functioning machine... and that fixed it.

Hi Earl,

It sounds as though something is amiss on the mobo. If the mobo cannot
return a "good signal" instantly upon power-on, it will shut the power
supply down. Lights, fan, everything.

Trying your supply in another machine, and swapping a different one in
yours, just about seals it.

Good luck

Just read your post about replacing the mobo--congratulations!

There could also be a small power switch on the back of the case somewhere
near where the power cord hooks up. I accidentally hit this switch while
moving the case and I almost went crazy in the attempt to find the solution
to the problem. I have to be very careful about this when moving my computer
case.

Thanks for the update. Glad to hear you got it sorted!
