So for the past week or so my computer at random times has been getting glitching and getting green/pink/blue small dots scattered all across my screen. I can’t move my mouse or anything so I do a full power off. Restart it, it works but then does the problem a few hours later. Also for about the past year when I start up my computer I hear a rattle in the system for the first like 2 minutes while it starts up. I’ve had the PC for 2 years. Is it time for a new one? Is my GPU dying? Any help would be appreciated!
