Based on my own Web research, it would seem that my laptop has a bad CPU. I am writign to this forum hoping to find confirmation of my diagnosis before I spend any money to fix the problem.

 

When I try to start-up the laptop it hangs-up with a black screen, sounds as if it is trying to read something from the CD tray, and blinks the LED lights by the CAPS lock and NUM lock. According to the link I am pasting below, the CPU has stopped functioning. I want to be sure this is accurate before I buy a new CPU. Could there be other issues I need to address here?
