Multiple people in our organization (20 of 100) are reporting the BSoD STOP 0X0000000A IRQL_NOT_LESS_EQUAL. We have run memtest, scannow /sfc, the PSTAT command line process, we've run windows updates and Thinkpad driver updates. Virus scan finds nothing. I do not understand the messages in the event log or the minidump. These are all IBM T42's RAM=512MB 1.7GHz Intel Pentium M processor network card= Intel Pro Thanks for your help.
