I was playing Minecraft smoothly like any day... When it started to freeze every 3 seconds or so... Then a white screen and a Windows notification saying that the video drivers crashed. Also, a pop up saying that Java is not responding, and with the options to close the program, open debug or search a cause. I thought "Uh, must have been because I was rendering a 4K image on Blender while watching a 1080p video on Youtube and playing Minecraft at the same time on a GTX 650... I was wrong. Every single session after that, the same things would have happened. Can somebody help? Thanks.
