AGP Slot In Use

Hi,

I'm trying to install an AGP, ATI video board. When I take out my PCI, ATI board and put in the AGP, and try to boot, the system gets to the Microsoft logo screen and stops. The logo screen is very dim.

With the PCI board back in, everything is fine.

When I use a diagnostic program such as Everest, it tells me that the AGP slot is in use. It isn't.

Anyone have a clue?

CPU Type Intel Pentium 4, 2400 MHz (18 x 133)
Motherboard Name Asus P4V8X-X (5 PCI, 1 AGP, 3
Motherboard Chipset VIA VT8763 Apollo PT800
System Memory 3072 MB (PC3200 DDR SDRAM)
BIOS Type Asus AMI (11/12/03)
Operating System Microsoft Windows XP Professional 5.1.2600 (WinXP Retail)

Thank you,
Ed

 

Yes, Pete, I've done all that. There is no setting in the BIOS to enable or disable AGP.

I also had the owner of a computer repair shop try to install the board. He tried everything, with no good news.

The board works perfectly in other computers.

Thank you for answering.

If it is happening after Windows has started loading it is very probably a driver problem.

Try booting into Safe Mode with the AGP card. If it works OK there it should be a matter of removing any and all of the old drivers, setting the drivers to a standard set to get to normal mode and running the installation of the new drivers then. You can try the method in the sticky at the start of this forum, but I don't trust "driver cleaner" programs not to remove something important...particularly with complicated drivers like graphics.

If you are removing old drivers, check in Add/Remove Programs first, then remove any drivers listed in Device Manager.

Thank you both for your answers.

I can't boot in any mode.

I've made sure to remove all drivers before trying the install.

I can put the new board in many other computers and they will boot just fine, without any messing around with drivers. In my computer it stops the boot process.

I'm about 100% convinced that Pete is correct about the MOBO problem. I can't see anything in the AGP slot that looks bad. I've decided not to take the MOBO out, it's too much work and too much chance of something going wrong - I'm super clumsy.

Guess I'll live with the PCI until I can afford another MOBO.

Thanks again for your answers.

Just a thought, may not be the cause of your problem but it wouldn't hurt to check. Some mother boards share IRQ's between the PCI and AGP slots, I believe your board shares PCI slot 4 with the AGP. You might check to see if there is a card in that PCI slot and if so move it to another free slot if possible. If that's not possible, you might check in BIOS and see if PlugNPlay BIOS is set to yes to allow Windows to assign IRQ's.

I've run into cards that didn't play nice with shared IRQ's and was successful in getting around the problem by either moving a card or changing the setting in BIOS. May not help but it's worth a check.
