I'm going to add my question on the same problem to this thread. HP Laptop was working fine for a long time. Nothing changed except now it is getting the BSOD with IRQL_NOT_LESS_OR_EQUAL message. Now comes the weird part. At the computer store or at another house it starts up just fine but take it back to the house where it is primarily used it gets the error message again. Thinking it has to be a network problem, can start it up in safe mode without networking. Any thoughts?
