I am having trouble with my Dell Inspirion 1150 laptop. When I turn my computer on I am getting a blue screen after it finishes loading and it shuts off and starts up again. It does this over and over. The blue screen says something about DRIVER_IRQL_NOT_LESS_OR_EQUAL. What does this mean and how do I fix it. Do I have a virus or do I need to update a driver?? Please help.
