This happened to me twice, and I have deduce that it is because of VirtualBox because it is the only installation that touch the drivers I've done recently. It seems to happen after waking up from sleep mode (with a delay of about five minutes). This corresponds to the indication of Microsoft about this BSOD : ''This bug check indicates that the driver is in an inconsistent or invalid power state.'' You should have more information in the minidump attached. Maybe this ticket can be related to [ticket:7930 this other]." defect closed host support VirtualBox 4.0.0 worksforme bsod DRIVER_POWER_STATE_FAILURE crash other Windows
