Re: computer keeps restarting please help!!!
Have you tried reformatting your HDD? Your dell should have come with CDs with windows and the drivers. Basically just wipe your hdd clean and install a fresh copy of windows and the drivers, update everything, and it should be good. This happened with my old hp desktop (windows would start up but then just keep restarting) and i just reformatted it and works just fine.
