Driver_IRQL_NOT_LESS_OR_EQUAL
This message is displayed and I can only shutdown my
computer.
Very LONG URL from Microsoft site below. A device driver is the likely
cause. You could try roll back drivers if you have recently
updated/installed something.
Good luck, jf

Stop 0x000000D1 or DRIVER_IRQL_NOT_LESS_OR_EQUAL
The Stop 0xD1 message indicates that the system attempted to access
pageable memory using a kernel process IRQL that was too high. Drivers
that have used improper addresses typically cause this error.
Interpreting the Message
This Stop message has four parameters:
1. Memory referenced.
2. IRQL at time of reference.
3. Type of access (0x00000000 = read operation, 0x00000001 = write
operation).
4. Address that referenced memory.
Resolving the Problem
For additional troubleshooting suggestions that apply to all Stop
errors, see "Stop Message Checklist" later in this appendix.
* Stop 0xD1 messages can occur after installing faulty drivers or
system services. If a driver is listed by name, disable, remove, or roll
back that driver to confirm that this resolves the error. If so, contact
the manufacturer about a possible update. Using updated software is
especially important for backup programs, multimedia applications,
antivirus scanners, DVD playback, and CD mastering tools.

Knowledge Base link on the Web Resources page at

keywords winnt, 0x000000D1, and 0xD1.
