I have a 980Ti and it's been working fine for the last 2 years but lately I'm getting this problem - https://gyazo.com/a4bbb95c0db88a8df2a70b9368050879 Does anyone have any idea on why this is happening. It can be felt in game, I go from 120 to 40-50 fps and then it resets again to 120. It's not a memory leak and not restricted to one game, every game and benchmark is the same. I was thinking it might be my PSU but I'm not sure, I've done a full driver reinstall, no overclock, etc. I've had my PSU for 5-6 years and it's a 550W FSP PSU, so I think it might be the problem. Here are my specs: i7 3770k @ 4.0 Ghz 16 GB DD3 RAM GTX 980Ti Windows 10
