So 2 days ago I was playing skyrim and went AFK for around 1-2 hours. When I came back the whole screen was buggy and the pc was not reacting, up to the point were i used the power button to put my pc out

Since then I cant open Opera, always when i open it, the window of opera is open ( and i see p.e. that my tabs are still open, but it stays minimized. Which is kind of frustrating.

I already tried, reinstalling, restarting, changing my screen settings( i use 2 screens, so i tried to unplug them etc.)

I tried to add a picture of what i see, even if it is not much maybe somebody can help me?

THis is all i see from opera:
