When im playing my games on my pc after about 20-30 mins my computer blacks out for a few seconds and sometimes the game crashes saying my GPU has stopped working, now reading online i figured this meant my GPU was overheating so i downloaded GPU-Z to monitor my temperature and while playing its reaching the high 80's when not to long ago it would only reach maybe max high 50's. iI do not know where this is coming from because i regularly clean my PC for dust and such. I have a GeForce GTX 550 Ti with a 700W PSU. I've had all this for about two years now and i do not overclock at all. Could my GPU simply be dying?
