AGP Video Card not recognized

Hi All: Just finished building a new machine, went to boot it and got motherboard beeps for video card error. So I swapped out the video card for the first one I found lying around. No more video card error machine booted fine and I installed XP Home.

Then I noticed (I really hadn't been paying attention) that the video card I had installed was a PCI card. Well, I want my AGP4X, so I shut down and put an AGP card in. Figured after Windows recognized it I could install the correct NVida driver. I left the PCI card in the machine.

Machine boots fine but does not recognize the AGP card. Tried a couple of different configs, with and w/o PCI Card. No PCI card, mainboard says video card error. Just happened to have another AGP card, plugged it in, same results.

Checked everything I can think of, Need lots of help. If this is a mobo failure I'll be

MOBO is Shuttle AK32E, 364mb ram, Athalon 1000+

Hi martinr121.

Take all PCI video cards out and plug in the AGP card. Go into the bios and tell it to use the AGP port for the video. You should be able to tell it PCI or AGP. That should do it if you're running XP.

If not, you need to put the PCI card back in, boot up and then change the video driver to the Microsoft VGA driver. That will kill the bootup using the drivers for the PCI card and maybe not recognizing the AGP card. PCI out and AGP in and boot. Then you can load the AGP drivers.

Let us know how you made out.

Hey Giles: Thanks a lot for helping on this, first fix won't work, can't get anything, including bios with only AGP card in.

I booted with PCI card, installed NVida AGP drivers. shut down, reboot with only AGP card. Again, nada. One long, two short mobo beeps indicates video card problem, then nothing.

Put PCI card back in, boot machine, device manager only shows PCI card under display adapter. New hardware wizard can't find
installed AGP card.

I booted with PCI card, set BIOS for AGP first display, ( your second suggestion, drivers already installed) shut down, pulled PCI card, installed AGP card, rebooted, one long beep from MOBO indicating video OK, machine boots, no video!

As they say in the funny papers: "AARRRGH "

 

104. The next two things I would look at is (1) does that particular motherboard support those particular AGP cards and (2) possible AGP problem on the motherboard seems more and more true.

I suspect mobo problem, will call Shuttle Monday, meantime will run with PCI card.

I'm not sure how to check for AGP card compatability with mobo, just seems unlikely two cards NG. Shuttle's website no help.

When I get it figured out I'll post back.

 

Older AGP cards are 3.3V, newer motherboards only support AGP 1.6V cards... may be your problem.

RASelkirk: Are you talking about voltage?? Even so, I have minutely examined both cards, can find no reference to voltage on them.

 

martinr121,

You probably won't find anything mentioned about voltages on the cards. However, as shown here, your board provides both voltages so I don't think that's the issue here - especially since we have two card thats don't work.

If you know that these cards do work when not installed in this board then I cast my vote for a bad/malfunctioning AGP slot.

Cheers,

ICE.

 

Iceolater: Thanks for the input on this.

Based on what I can gather from this site:

www.ertyu.org/~steven_nikkel/agpcompatibility.html

both my AGP cards are compatible with all voltages.

Seems like it is going to turn out to be a MOBO AGP slot problem, I hope I don't have to replace the MOBO. I'll call Shuttle tomorrow and see what they have to say. Will post back results.

Well I'll be darned! Called Shuttle, spoke to Tech Support guy,
explained problem.

He says: "Shut down computer" I do.
He says: "Remove PCI card" I do.
He says: "Clear CMOS" I do.
He says: "Plug in AGP card" I do.
He says: "Turn on machine" I do.

Machine boots, video display, card recognized, New Hardware Wizard installs drivers, display resizes, all AOK!

I say: Well, I'll be darned.

It should all be this easy.
