DRIVER_IRQL_NOT_LESS_OR_EQUAL If this is the first time you have seen this stop error screen restart your computer. If this screen appears again follow these steps. Check to make sure any new hardware or software is properly installed. If this is new installation, ask your hardware or software manufacturer for any windows update you might need.
