WHY Frequent BSOD: INVALID_WORK_QUEUE_ITEM 0x96 ntoskrnl.exe
Posted: Fri Sep 30, 2011 4:24 pm
This is a X61T fresh from factory restore (XP Tablet PC) machine probably with a few small apps like ZIP tools installed.
It BSODs every 10/15 even if left idle and not doing anything. It was doing this even before the Broadcom Driver got on board.
