I wonder, and would like to know...
...has anyone here managed to install any graphics card on a Dell Optiplex GX 280?

I'm trying to install a Nvidia Gforce 7 card but nothing will do.

I've tried to put the card in the computer and moved the display cable to the new card and I get a signal error, and when I move the cable back I'm told that a new card was detected and that I should move the cable.

The installation disc for drivers says that it cannot install any drivers when it cannot find the card, and with the card there's no display.

setting up videocard priority in the boot menu won't help either.

I don't think there's any physical problem on the comp or video card (and I don't think the guarantee still works) so only if I could somehow trick the computer to accept the card I believe it should work.

any ideas?

do you have your bios set to use AGP(or PCI) as the primary video card?

You need to disable the onboard card in the bios then signal should switch over to the upgrade card you are installing.

Normally there is a message say which F key to hold at boot up to get in the bios.

How do I disable the onboard graphic? I've tried the boot menu...
And yes my integrated is AGP and my new is PCI Express, I don't know how to switch.

The error msg is the display's built in program that triggers the message when the display's switched on but can't comunicate with the computer.

Normaly you use the arrow keys to move around

enter key to select the option

and either up/down arrow to change or page up/down to change.

when you exit the BIOS you have to select an option like exit + save for it to take effect.

Most bios now adays (even most old ones) will auto switch over to the new card, but you still need to set AGP or PCI express in the bios so next time you upgrade PCI you won't need to do anything except install the newer card.

"I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road."

I know the prob now, My Dell Optiplex GX 280 originally comes with a 280W Power source and newer computer components require at least 350 W

So that's probably the simple problem

Raise the threshold until you crash, then TRY HARDER

Thats not much difference in power, but could be a problem.
Other ideas:
Card has additional power connector not connected.
Card is defective.
Card not properly seated in socket.
