Return of the Insidious BSOD

[DanDMan]

...just when I thought it was safe to go back in the water...

My wife's computer has been acting a bit strange lately. Sometimes, when she boots, zonealarm will ask if the Spooler Subsystem can access the internet. Before she can respond, the computer will spit out a quick Blue Screen of Death (BSOD) and reboot. She thinks it happens most often when she boots the system before powering on the USB printer...

Now, today during one of her productive periods, the computer spat out a BSOD and finally stayed long enough for me to write down the error:

***STOP: 0x000000D1 (0x00000015,0x00000002,0x00000000,0xEB6A2B46)
DRIVER_IRQL_NOT_LESS_OR_EQUAL

Address EB6A2B46 base at EB6A0000. DateStamp 3325ba6e - uhcd.sys

Beginning dump of physical memory

I searched google for 'uhcd.sys' and found articles relating to USB - but mostly on older OS's (like Win95/98). The MS KnowledgeBase didn't seem to have anything that matched...

Any suggestions? I really don't like my wife's computer dumping in front of her...
