Blue screen but no blue screen

[magma6]

So sometimes when I'm in loading screen in LoL it appears a blue screen,but not quite a blue screen.The image freezes and the sound of the blue screen appears too.It stays like that if I don't shut it down myself.Like I said the sound and the characteristcs of the blue screen are there but the actual blue screen doesn't appear.And when I open the PC nothing weird happens,it opens normally.What can I do?
Windows 10(laptop),8GB RAM,Intel 1-7 5500U,Nvidia 240M 2GB.

The BSOD isn't blue anymore. Hasn't been since Windows 7. You get a frowny face now
