Windows XP Error Shutting Down

When shutting down WindowsXP Professional, my system is locking up with the following error (Note it saves my settings then gives me this):
Driver_irql_not_less_or_equal
Stop: 0x000000D1
WDMCAPI.SYS Address F6cc0E84 base (lots of addresses) @ F6C91000

datestamp 3b0cd3ac.

It does this every shutdown. It began after installing my ISDN PCI modem (had XP drivers sent to me from their website - Hayes), though modem works no issue (drivers did say not Windows XP certified during install). Any help? I disabled reboot since the system used to do that prior to this change. Note the following is the system specs:

Abit TH7II MB, 2GHz P4P, 256MB RDRAM
Plextor 16/10/40a (no software installed - put CloneCD on)
60GB WD HD
GeForce3 Leadtek card (latest NVIDIA drivers)6.13.10.2311
Creative Labs Audigy Card - driver 5.12.01.0134 English
 
An 0X000000D1 DRIVER_IRQL_NOT_LESS_OR_EQUAL STOP error is a software or device driver issue. The error appears to be due to the WDMCAPI.SYS device driver, which is almost certainly for the ISDN modem.

The troubleshooting guide for hardware failure STOP errors in WinXP Pro is on this <A HREF="http://www.microsoft.com/WINDOWSXP/pro/using/howto/gettingstarted/guide/troubleshoot.asp" target="_new">page</A>.

Thank you - will begin the debugging process. Pretty clear it is the modem from reading the posts. Back to Zoom/Hayes for another go at the ISDN/PCI drivers.
 
You're welcome. Please let us know how it goes; we like to hear about the solutions! Someone else might find your post very useful in the future.

Good job posting about the error message ... most people don't provide enough information.

Still having problems. I flashed the ABIT BIOS - same problem with same stop error. I manually disabled the IRQ10 that the modem was using in the BIOS, the stop error then moved from the modem driver (WDMCAPI.SYS) to the 1394 driver on my Audigy Soundblaster (nic1394.sys)! I manually disabled the 1394 under 1394 and network locations, and the stop error 'stopped', but of course I have no 1394 at this time (modem interrupt went from 10 to 12, and 1394 was 11). Can anyone help explain what the 1#@$^ is going on? Originally, IRQ10 was not being used by any other device other than the ISDN-PCI modem. I'm I having some sort of driver conflict between the Audigy and the Hayes (though not sharing interrupts)?

Abit TH7II w/2GHz P4P
Soundblaster Audigy (European version) Driver 5.12.01.0134
GeForce3 w/NVIDIA 6.13.10.2311
Hayes Accura ISDN-PCI modem model 08-15720
 
Hi, jm ...

From your description of the problem, it's beginning to sound more like a resource allocation issue than an actual driver conflict.

While it's just a guess, I'd suspect the Audigy card. That sound card needs three IRQ addresses and 2 DMA channels. Not all hardware plays nicely with others, even with ACPI enabled.

Disabling the IRQ's in the BIOS is probably not a good idea, if a lack of IRQ's is the problem in the first place. The fact that the STOP error "moved" is indicative of a problem with Windows allocating the resources, instead of a driver conflict.

Here's a few things to try:

If you don't need your serial ports, disable them in the BIOS to free up the IRQ's.

Then try moving the sound card to a different PCI slot. Or removing it to see if the conflicts go away. If the STOP errors cease after removing the card ... there's the source of the problem.

If moving the sound card simply causes more, or different kinds of conflicts with your other devices, you might think about installing a card that is a little less of a memory resource hog.

The lastest nvidia drivers 23.11 can cause problems with xp. Intinite looping error which I myself had. The XP certified drivers seem to run much more stable.
 
There isn't anything in this thread that really indicates a problem with an "Infinite Loop", or the nv4_disp.dll issue with the 23.11 nVidia drivers.

ACPI is normally enabled by default. Although it might be necessary to reload the system as APM in order to have manual access to the IRQ's. That is possible with WinP Pro and Win2K ... but not WinXP Home.

It was good idea ... but just not likely to be the problem in this case.

You are welcome for the link.
