Graphics Card not working?

Question

My friend put a new motherboard and processor in his computer, The
card is a 8X agp and so is his motherboard slot.

He booted it up there was sign of life and posted, but the display didn't come on.

He has checked that it is in properly etc.

Any Ideas

Thanks,

Jay

He has had the card previously installed, with the old motherboard and processor, he has no onboard video.

You can only hear it post, nothing comes up on the screen.

Answer 1

several things could go wrong with a new motherboard+processor

Is the new motherboard compatible with the power supply in the case

Is the monitor plugged into the graphics card at the back
Is the monitor switch on

If you can get to the bios, then you might have to toggle a switch to change from pci to agp in there.

If you have a spare pci graphics card lying around somewhere then this might be a good time to use it to test if that is the problem.

Other than that I would check all the other connections inside the computer.

Answer 2

A little more info would be nice, but lets see if we can get started.

When you say "there was sign of life and posted." did you actually see the post test or did you just hear the beep and could here the harddrive grinding to life?

If you saw it come up once then nothing are there any other signs of life?

I know when ever i put a new motherboard in i check and make sure that all the fans and things are running. Sometimes that ram chip can "look" snapped in but need a real good smashing in there.

If the ram isn't seated it wont do anything but star at you with its little LED lights on and fans roaring.

get back with some more info and we will look at some more troubleshooting ideas.

Answer 3

Assuming you're trying to boot up into Windows XP, it sounds like the display settings may not be able to support the card, possibly because the card's drivers haven't been installed yet.

I'd suggest that at boot (just before the first Windows logo appears) hit the F8 key, then choose "Safe Mode with Networking" to boot into safe mode. From there, download and install the latest drivers for the card and install them. If safe mode won't allow the drivers to be installed, adjust the display properties to standard VGA (640 x 480) resolution, and boot into normal mode and install the drivers.

After rebooting once the drivers have been installed, try upping the resolution and hopefully all will be well.

Answer 4

you mean he can hear it post but nothing is on screen? or the post is on screen then nothing after?


without any form of graphics the pc wouldn't even start in most cases.

is there onboard video on the motherboard? see if the monitor will connect to the motherboard... you may need to disable the onboard graphics.

Answer 5

Is it in the AGP slot and is the bios onboard been disabled?, is it not a PCI express slot on the board which is dark in colour if it is he needs a PCI express card, AGP slots are lighter in colour.

Answer 6

Does his motherboard have onboard video? If so, try plugging the monitor into that and disable it through BIOS...then plug it into the AGP card.

Answer 7

May be any of the cards is defective
May be cards are not compatible
May be the driver is not proper or corrupted
May be there is a conflict

Difficult to answer with the limited information you have given.

Also if you are able to provide sufficient information to resolve your problem you yourself would be able to detect the fault.

Answer 8

If your computer is not working properly while you are working on it, it could be a problem with device drivers, hardware or software.
