I have my gpu for about 3 years and i knew it was bad as it is an old amd HD 4770 and i was about to replace it. But i formatted my pc before 3 days and i was actually impressed by my gpu being so silent under heavy gaming and while idle. Well today i finished some windows updates and it all went bad. The gpu started its all habits of the fan speed going up and down every 3 seconds. I know its the windows updates that did it and there is no fault with the gpus drivers cause i updated those 2 days before and it was good. Anyone has any idea?
