Hi, I have had the following blue screen message extremely frequently while playing warhammer online. I have searched and searched with no avail. My system is more than good enough to run the game. I have checked my memory, my video card drivers are up to date and I have tried re-installing the game several times. When I google the error message; similar messages suggest it may be a network driver issue. Anyway Here is the message I always get. It never changes. Dxdiag attached. driver_irql_not_less_or_equal Error code 100000d1, parameter1 00000010, parameter2 00000002, parameter3 00000008, parameter4 00000010.
