Hello All,

could you please help me with issues I am having while playing games? My PC is working perfectly fine browsing the internet, playing videos etc. but once I start play a game (Witcher 3) problems starts. I have noticed the problems will always occur once my Graphic card warms up around 67-70 ° C. Then some flickering lines start to show up, then bigger ones and finally game or whole pc crashes - resulting in restart or crash to desktop.

I have tried multiple solutions I found here or elsewere on the internet but nothing helped me. I have even formated my SSD and re-istalled windows, Also I have tried to install older Drivers. Also I have removed my Graphic Card and RAM from MB and put them there again. I changed GPU power cable a tried to insert VGA cable to different port.

I have tried to run Heaven Benchmark 4.0 - same issue as in game. Once my GPU hits 65-70 ° C flickering lines shows up.

I did not change any components recently and all worked fine until now. I am worried my Graphic Card might be dying. Could you please help me to try other solutions first so I can avoid buying new GPU.

My PC specs:
Intel Core i7-7700
HyperX Fury Black 16GB (2x8GB) DDR4 2400
MSI B250 KRAIT GAMING - Intel B250
ASUS GeForce ROG STRIX GAMING GTX 1080 DirectCU III, 8GB GDDR5X
EVGA SuperNOVA 750 G3 - 750W
Windows 10
