|
 |
Evening everybody!
I'm not an idiot regarding computers so this really leaves me kind of amazed and you are like my last straw of hope.
My girlfriend's PC is pretty old... We're talking 128mb RAM era here.
So beginning of last year she got the internetz so I installed a network card into her PC - worked so far.
Last week her network card got fried, yes fried, the whole deal with sparks and all.
(That still amazes me already)
So I organized a new one (gladly I could get "borrow" one from work).
It was still in the box so it was definitely new and unused.
I installed it into her PC (just as a precaution I used a different PCI slot so that shouldn't cause the problem)
Network card installed, check.
pc starts, check.
I switch the display on it says "No signal detected" and stays dark, wtf?
I remove the network card, everything runs fine again.
At first I thought the PSU was too weak but then the system wouldn't start in the first place, right? (Never actually had a PSU that was too weak)
It sounds like the system starts normally, but since I can't see shit, I can't say that for sure.
The display is working flawless (but only without the ethernet card)
Any hints on what that could be and how I could solve it?

Does the mobo have built in ethernet? If so, you need to disable it first in bios. If it does, no need to use the ethernet card. If mobo does not have built in ethernet, then try a different PCI slot. Make sure its pushed in all the way. If still goes black, try the card on another PC. If that pc goes black, that the ethernet card is Bad. I have a feeling your ethernet is broken.

Maybe a BIOS conflict (that IRQ stuff I never understood)
Or maybe a hardware problem, use another PCI slot.
Also, reseat the gfx card in case there's some short-circuit weirdness going on.

Yeah probably a IRQ issue, If you installed the card directly below the AGP slot sometimes this will happen.

No on board card, if it had one, I wouldn't be installing one 
Already tried two different slots it's the same with both,
but I'm gonna try the rest of those slots anyway but before that I'm gonna make sure there's no dust in it.
And I am gonna put the card into my PC tomorrow although I highly doubt it's broken, I never had a _brand new_ out of the box card that was broken.

I would wonder if when the orginal card went bang, if it actually fried the pci slots? Even though the machine works without a card in there, as soon as you plug something in one of them, its just creating a short and then will refuse to boot.
