I have noticed that most laptops tend to have this problem, well it can be fixed with this solutions below, remember that the proper thing to do in times of having this problem is to take it to a laptop engineer...

Let's begin...

Fix 1: while powering the PC, hold the D button along with the power button....repeat continuously until it displays, when it displays, it would show a variety of colours until your PC boots up normally.
N.B: you can use Fn or F8 if the D does not work.

Fix 2: Uncouple the whole PC down to the motherboard, then unscrew the heat cover on top the graphic ic, then heat it up with a blower, or you can use a hair dryer for about 10 minutes, with intervals for cooling to occur.

Fix 3: Sometimes, it makes some beeping sound, about 8times continuously, this is to signal that something is not connected properly in the system. You have to unplug all cords, hardisk, ram, screen monitor, clean with a soft brush and fuel or spirit, then allow to dry before connecting them back.

N.B: You have to take extra care not to damage any important part of the PC

Hope this helps....
