RX 480 fps stutter after power outage

[renatus]

Hello, I recently had a power outage and had to reset my windows because my windows files were corrupted. I had no problem before resetting my windows but nowadays there are frequent frame drops and sudden hangs. You can witness this in the video and my performance recordings. The only game I played is almost "League of legends" and my system is far above the requirements of this game. I tried to play "Witcher3" after a power outage. I realized that my game was not smooth. Please help me. Two things I need to add and want to remind. there is one: I wasn't experiencing any framerate drops before resetting my windows two: I have tried to install my windows cleanly 2 times and I'm sure the drivers are completely clean.

My System:
INTEL CORE I5 3550
8 GB RAM
RX 480 8GB

since it's a fresh windows copy, i would check all power settings and make sure they are all set to max performance, as a start.
