After 9 months of serving me loyally my GTX is finally starting to show problems. My computer freezes on one frame and doesn't move until I restart then when I restart I see artifacts all over the place and freezes after about 2 minutes of use. I updated the driver before it froze again. Check temps maxxed out at 70 while playing oblivion. Shouldn't been temp problems. No power problem TT Toughpower 750W. So any suggestion to what is wrong would be nice.
