video & modem irq conflict- change IRQs?

By rbwyes ·
I recently installed an NVIDIA geforce2 mx/mx400 agp video card in my computer. Device manager shows its sharing IRQ 11 with an onboard Advance AC'97 audio for VIA Audio controller and a Supramax 56i PCI v.90 modem. Often, not always, when the modemis used, (and sometimes when it isn't), the computer suddenly reboots, losing anything I was doing. The support people at NVIDIA said move the modem to another IRQ. I haven't been able to do that yet. The option isn't available. I'm running Windows XP Pro, have tried changing the bios(Award v6.00PG, moving the modem to other PCI slots, to no avail. Any suggestions on changing IRQs, etc.?

As you see, XP does not allow you to set resources manually.

Do you have the latest XP drivers for the modem and the VIA audio?

In BIOS settings, set plug and play OS to no.

I have had several systems where I had to switch to different modems to get around shut down issues.

I have had different conflicts with irq sharing. One thing you can do is to uninstall the drivers in one of the devices, power down, remove the device. Reboot, let windows come up without it installed. Then power down again, install the device reboot and usually it will assign it a different irq.

In your case I would uninstall the sound drivers and then the audio card.

If you had installed XP with theses devices all at once this seems to happen. My conflict is always one of my pci slots and my onboard network slot. I did this and it worked beautifully.

Another option is to disable it in your bios (if it is an on-board device) boot to windows with it disabled, shut down and then re-enable it. Reboot to windows and walla! you have a different irq allocation for that device... usually.

Good luck!

As Chas said trun off plug and play.

Windows is still running on the physical irq numbers from the 8088 days 16, All of the new goodies in the system take up all of them and then some so they have created the virtual irq. That's 11.


Uninstall all of your cards, if you can, except your video card. Once it has been established in an irq setting install one card at a time till everything is back in.

If you have intergrated devices you will have to disable them in that profile. Then bring them back one at a time.

Good Luck this has driven more than one tech to Wild Turkey.
