Okay so i have this problem with my desktop pc, while im gaming i see artifacts and red dots all over my screen. Sometimes its like that just when im on the desktop as well. i have tried everything, new drivers, system restore, antivirus to make sure my pc didnt have any viruses. I see alot that people say that it is because it is over heating but one day while it was working the card only maxed out at 53C and that was after playing for a couple hours. please help me the card is a Nvidia GTX 745
