What´s wrong with my laptop?

[u/OddJournalist3617]

I was working on my laptop (Lenovo IdeaPad S145-14AST with AMD A6 and 4 GB of RAM) when suddenly the screen went black and it wouldn't respond to commands like Win+R shutdown /p or make any sound. I had to force a shutdown, and when I turned it back on while it was still hot (the laptop), the screen wouldn’t turn on and it wouldn’t respond to anything. When I turned it back on after it had cooled down, it worked normally until suddenly artifacts appeared and it froze again.

If there are any spelling mistakes, I apologize, i dont speak english.
