When shutting down WindowsXP Professional, my system is locking up with the following error (Note it saves my settings then gives me this):
WDMCAPI.SYS Address F6cc0E84 base (lots of addresses) @ F6C91000
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)220.127.116.111
Creative Labs Audigy Card - driver 5.12.01.0134 English

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)?

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.
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.
