Whenever I start up my laptop, it automatically goes into Dell SupportAssist, saying "Your system seems to be having trouble starting. Dell SupportAssist is scanning your hardware for a possible cause." I've let the tests run and when it's finished, it says there's no problem with my hardware. The pc restarts by itself and it starts all over again. I've tried following Dell instructions like taking out the battery and unplugging the power cord and holding the power button for x amount of time, but it doesn't work. I really don't want to go out and buy a new laptop right now. Does anyone know how to fix this?
