Hi there got this from: Windows XP Blue Screen of Death STOP Codes
Stop 0x000000D1 or DRIVER_IRQL_NOT_LESS_OR_EQUALThe Stop 0xD1 messages 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.
Possible Resolutions:• 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.
So I think what you should do here is try uninstalling all drivers or software that you have loaded in the past two days and re-loading it.
Let me know how things go. Also when re-installing drivers make sure you have up to date drivers that correspond with the hardware. Cool
