My pc will not load windows normally. It continually reboots sending me to a blue screen with the error message of: Driver IRQL not less or equal. tech info: stop 0x000000D1 (0x75FFFFE3, 0x00000002, 0x00000000, 0xFA1B52B8). What does this mean? Also it no longer registers my mouse but my keyboard works fine. They are both PS2 and connect into the same little box.

Is this a new problem? Were things working OK previously? Any new hardware and or software?

If this is a new problem try a System Restore to a point prior to the problem:

start > All Programs > Accessories > System Tools > System Restore

That error can also be caused by Logitech Mouse's as seen here:
