Mother board or vidio card

lonniec1143
I am working on a freinds computer. She had problems with the monitor. nothing would come up, the monitor did not work at all. I replaced the monitor with a known good one and still nothing. I put in another video card and still nothing. The only thing left to try was a new motherboard and still nothing. What can it be? Coulod a refirbished mother board that I had recently purchased also be bad?

Possibly badly seated or broken RAM, CMOS battery could be dead, CMOS jumper could be in the reset position (or may need to be reset)

Try putting the jumper in the reset position, start the system, if it doesn't auto turn back off, wait a moment then turn it off, move the jumper back to the run position and start again.
The jumper is usually right next to the battery.

tried battery and cmos jumper and still nothing. The first mother boards lights indicated other failure. the new mother board indicates IDE Bus failure.

Which you did not mention initially.

If you installed a new board, I highly suggest you ensure that it is not grounding out on the case.

It's a Dell Demension 8300. The motherboard comes on a motherboard tray. It snaps into the case rather than being screwed down.

What are the odds eh, but as you say, two different errors, two different mother boards.

If the IDE bus is bad, it's bad. Ring Dell, if you got the replacement from them. If not, take it back where you got it.

Is the PC booting and giving normal bootup beep codes?

Are keyboard lights lighting up, and does the caps lock work?

The first mother boards lights indicated other failure. the new mother board indicates IDE Bus failure. The key board lights come on and so does the cap locks

plugged in backwards, or the drive is not getting power. Does the error go away if you unlplug all IDE cables?

You might try a different power supply.

Is, having tested the original monitor on another system at the outset. Assuming the second, known-good monitor was indeed good, I suppose you accomplished the same thing, and I don't fault you.

I guess the only good thing about this is that you are doing it for a friend, at no charge. If you are charging, you are going behinder the further you get, even at minimum wage.
