XT983 Repair Q, what am I forgetting?

This PC is just driving me nuts...

I'm working on my dads XT983 (Wal-Mart special). The story is that one
minute it was fine, then he left for about 30 minutes, and when he
came back, no video and the computer isn't responding. When you
restart it, you hear the fans and HDD click on, but you do not hear
the normal beep sequence; implying, of course, that the computer isn't
making it that far.

The monitor is the one that came with the PC. It has an orange light
when there's no video signal, and turns green when it gets a signal.
On this computer, it stays orange now.

I've literally replaced everything I can think of, and it hasn't fixed
the problem. Here is a list of everything I've done:

1. unhooked all externals except for the monitor and power

2. unhooked all internal cards and cables except for HDD and power
supply

3. replaced mobo and CPU with new (the video card is built in to the
mobo)

4. plugged in a power supply that I know works

5. plugged in RAM that I know is OK

6. replaced the HDD cable

7. plugged in an HDD that I know works


Of course, one of the first things I did was check the monitor, and it
seems OK on a different computer. But I've replaced mobo, CPU, RAM,
power supply, HDD, and cables, all with no effect. Isn't that pretty
much everything that CAN be replaced??

I haven't replaced the switch, but it seems logical that the switch
must be OK since the mobo is getting the "on" signal.

Any thoughts on what else I can do, or what I've forgotten to check?

TIA,

Mike

The graphic card, you can put another PCI graphic card on your motherboard,
it muss be Ok, i think. By the way, don't forget to switch off the viodeo
card on your mainboard.

Thanks for the advice. When I replaced the motherboard, the new one
had a built-in video card (just like the original), and this still
didn't help.

Any other suggestions?

Do check out the powersupply.
Very often the ps delivers enough power to get the system running but just
not enough for the video card (even build in ones).
Had the same problem very recently.

Okay, the first think the computer should do is beep, you get no beep.

Doesn't matter, you get no beep. Video comes later.

Why not unhook the HDD? The system doesn't beep, and it can beep without
a hard drive.

Can you get just this mobo to work?

Forget the HDD. Try going the other way. Replace a working system's
components with ones from the bad system one by one.

Doesn't matter. A bad monitor won't keep the mobo from POSTing.

Fine, so replace everything and you'll have two computers.

You need to test each piece, not each "everything but one piece". You
could easily have fried both your mobo or your CPU or both your power supply
and your mobo. This is *very* common, especially on older mobos with
capacitors with bad electrolyte.
