My gpu stopped working a few days ago and I guess I had to reground it and then it started working again. I noticed though that it was working harder than usual and when I checked one of the fans weren't spinning, but it was trying. It does have dust in it and If that can effect the fan then I will try as hard as I can to clean it out.
