black screen Black Screen Flickering

[Nat Teper]

Hello,
Recently i have bought Assetto Corsa as well as Project Cars 2. I noticed that after closing both games, my gpu would spike to 100% which was then followed by a black screen which would appear several times and any apps in the background would crash. Sometimes, the computer would go back to the lockscreen and seemed to be running at a much lower frame rate, somewhere around 20 fps. I then went to check my other games such as Forza Horizon 4 and ETS 2 and that didnt happen. Next i took out the graphics card to see if that was the problem, however, the screen was flickering after i booted the pc and there was a small artifact in the bottom left corner of the screen. This makes me think its something to do with the CPU however im not 100% sure.

PC: Lenovo Y520-T
CPU: i3 7100
GPU: GTX 1050 Ti
