About 3-4 months ago, I had the same problem. I took it to a computer technician whom I have known for many years and whom I trust. He told me that there was no problem with the hardware and that some computer software had been deleted and reinstalled them. Then he reset it and delivered it. The computer was working without any problems until 1 week ago, after which I had these errors while playing games. I started getting this error sometimes even though I'm not playing the game. I don't know why, but there is a problem like this. I don't get this error when the computer is not plugged in to the power cord. The computer does not freeze or freeze, but when I plug the computer back into the power cord, the same error occurs. If anyone knows, I would be very happy if they could help me. In addition, sometimes when the computer is idle and only Chrome is open, the CPU momentarily sees around 40%, it goes down, it hovers around 20%, then it goes down to 7%, it is very active, I wonder if this is the reason for this? The blue things in the image I mentioned below move slightly, and the black things do the same.
