Broken pc? I don't really know.

[Pycasso]

Soo. Something weird just happened to my pc few hours ago. And I don't even know how to explain what. I don't even know what to google for. 

I'm going too tell you what happened. I was just playing league of legends with a friend chatting on discord. Closed league and something didn't feel quite right. I wanted to open task manager and an error opened telling me something about task manager and system 32.I didn't read it all. Restarted my pc thinking that would solve the problem and this happened....(like in the video). Reset and turn on/ off didn't work so I turned my power suply off. Turned it on again and started the pc. Had a scurtcircuit sound and than it didn't turn on at all. 

I took out everything to see if something is burned but everything is fine. Turned my pc on again and this is what happened  https://www.youtube.com/watch?v=y-ZdTH5tsAY&feature=youtu.be 

The weird stuff happened at 36 seconds in.

This never happened to me before. And the only thing out of the ordinary I did was playing league.

Any help please?
