You need to connect an external monitor on your computer and then check are you still getting the same problem . if you are getting the same problem then you need to open your laptop and clean ram and processor fan.
Now install the fan and ram back in and then power on your laptop it should work fine now.

Connect an external monitor to make sure that you are getting video out to it. If that works you are having an issue with your LCD. If it does not, you are looking at some GPU problem. Let us know what you find.
