I've tried the [Fn] test by holding the Fn button while powering on the laptop. After a minute I get a set of 5 musical notes in a row that repeats 2 or 3 times, followed by a singular note 3 times, and then the muscial cycle repeats.

My AlienWare 51 continues to reboot after being logged into the OS for 5 minutes. I purshased a new PSU, a new MotherBoard(same model as the one that comes with the X51) I puled each Graphic Card one at a time, same with the RAM. I even re-installed the OS.

Most keyboards have a handy key that performs the logical equivalent of a mouse right-click on whichever screen item currently has focus (no mouse involved). The right-click usually brings up a context menu, of course.
