Hi, just now i was looking at my phone while there was nothing being done on the pc. All of a sudden my taskbar changes to white, everything starts lagging, and i hardly can move my cursor. I went to MSI Burner and saw that my GPU had around 80% usage with nothing in the background, just desktop, nothing else. Also the temperature goes from 45 to 60. It lasted for about 5 mins or less and everything went back to normal after that.
Does anyone know what happened?
By the way i have windows 7 if you need that info.
