Mobo/video problems

matpoh

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.

I tried it out of the case (thinking maybe a short) 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
3 Power supplies....235w, 250w, and Allied 350 amd approved ps.
3 agp video cards
1 pci video


Any suggestions?

if your board has onboard video then it will automaticly go to onboard video, you have to tell your mboard that it needs to use agp/pci instead.

For the boards that have onboard video, I have tried that as well. Still no signal.
