Almost in all games except (League of legends), my GPU temperature goes to around 83°C and then my pc just reboots. Is this a temperature issue or is my PSU getting old? I have an ANTEC earthwatts 650W which i've been using for a good 4 -5 years. Also, i've been using this card with the same PSU for around 2 years. My CPU temperatures are fine and acceptable. Any solutions? I'll try changing the thermal paste on the GPU and check, but i've read on forums that the 980ti goes up to around 90°C at load on certain games, so i'm not really sure what's triggering the reboots. I'm on stock cpu config btw right now with no overclocking. Please help.
