Sometimes the game just crash and it's closed without any error message. Other times is even worse, after a few minutes of gameplay the PC froze and I see a lot of weird lines on the screen, then the PC shut down (photos attached). I'm unable to play games in a gaming PC which is an absolute non-sense. Anyone knows how to solve this issue? or may I have a deffective unit?
I have the same issue when I use IA applications like Topaz Video AI or Adobe After Effects. It seems when the GPU has a lot of load, it just fail.
