Hi! I got an unusable laptop since a few days because of graphical glitches. They occur in bios, windows restore mode, when I leave the computer off for a while i can use it for 10 minutes, without it the problems start within 30 seconds or less. The computer is unresponsive, graphical glitches start and will reboot in the end. I tried disabling my GPU and uninstalling drivers and updates. I am at lost now.. Is my ram corrupt? it also happens during windows memory diagnostic..
