Janice's computer crashes

The first crash was DRIVER_IRQL_NOT_LESS_OR_EQUAL which resulted in a STOP 0x000000D1. The
error was in VIDEOPRT.SYS. Search turns up nothing specific, but an upgrade of video drivers may be the answer.
The second crash was a STOP 0x0000008E in WIN32K.SYS. Search turns up this: http://support.microsoft.com/kb/834450
The third crash is DRIVER_IRQL_NOT_LESS_OR_EQUAL which resulted in a STOP 0x0000000A
The fourth crash is again DRIVER_IRQL_NOT_LESS_OR_EQUAL which resulted in a STOP 0x000000D1 VIDEOPRT.SYS.
Another STOP 0x0000008E!!!
