I have a machine that I am pulling my hair out over. It was a machine I used during the school year for simple word processing and such. I took a couple parts out over the summer to use to test another machine, and when I put them back, I get no video signal and no post. I thought it might be the processor, so I tried it in another machine and it still works.

The mb I was using had onboard video so I tried an agp and pci video cards and still no video signal. I thought maybe I had fried the board and bought a new one. Same thing. I did some reading and the mb I bought had serious problems with the Thunderbird/Duron processors.

I bought an XP2000 to stick in it and no luck. I have tried about 5 different sticks of memory and 3 power supplies. All fans spin up but no video signal at all.

All I have installed is video card and ram. I have no ide cables or drives connected.

Any suggestions?
 
Your MB may be grounding out. Take everything out of your box and fire it up on a piece of wood.

Also, check to make sure that you mem is installed in the correct slots for your mem type and size.

Are you sure your Monitor still works?

What parts did you swap out?

Please list your full current system specs.
 
Well, I tried it out of the case and still no luck. I have a bunch of parts around and also tried a PIII-450 mb/cpu and it worked out of the case. I re-tested a bunch of ram and all 4 video cards I have been trying. All tested ok on the PIII system out of the case.

So far, here are some parts/specs I have tried.

3 Motherboards....Asus A7s266, FIC AZ31, ECS K7S5A-Pro
3 Processors....T-bird 1.1ghz, Duron 750, XP2000
About 15 sticks of ram from 64-256mb
2 Power supplies....235w and 250w. (Both test good, but underpowered?)
.....Would different mboards have differnet power requirements?
3 agp video cards
1 pci video

I'm leaning towards ps now but still not exactly sure.
 
What kind of monitor do you have?

Is it an LCD or CRT?

Have you tried swapping that out?
 
I have a CRT monitor. I have tried 3 different ones. The monitor works with the P3 board and all video cards.
 
I just tried an Allied 350w AMD approved power supply and still no video signal. I tried my old power supply in a machine with an xp2000 cpu and it powered up fine. Still confused.

Any more ideas to try?
