Lately I've had a few BSODs, if I remember correctly it said DRIVER_IRQL_NOT_LESS_OR_EQUAL, among other things, and identified the file tcpip.sys as a problem.
I opened the latest crash dump (from yesterday), I've copied the info below. I have no idea how to fix this.
My OS is Windows 7 64-bit (SP1), the laptop was bought new last September.
Any help would be greatly appreciated!
