hey there... i did something but i dont know what.... started messing with msconfig earlier...it seems to be shutting down now ! i also just finished going into task manager , ending the dell system select process. then installed ccleaner and it seems to have gone now. i just opened task manager again and its not showing. i downloaded the bluetooth driver, so one yellow triangle has gone from the device manager. only one showing now... i think that maybe tv tuner driver ?
