HP Pawilon not booting up

[Natcwi16]

Recently I found the problem with my notebook HP Pawilon. Problem occured about week ago, when I was looking on the net and suddenly the black screen occured. When I shut down the notebook holding the power button and then power it again, the screen light up, while I heard the fans rapidly accelerating and then shutting down while the screen remained black with only power button being lighten up. 
I tried many times to boot him up, but with no success. 3 days later the laptop started working again, I managed to look for problems with the windows but the troubleshooting found no errors. But the problem occured again, randomly while watching video on youtube. The screen remains black with the fans working for about 0,5s while powering up the notebook.
Do you have any idea while the problem occures?
