I recently switched from 60 FPS to 120 FPS. Everything was going great but like three days after, I wake up, and the fps keep switching from 120 to 90 to 80 to 70 or all the way down 40, then they go all the way up again to 90, but they never go up beyond that. It also seems like games do not detect the mouse correctly either now. It happened so randomly because I did not change anything other than the refresh rate and fps cap. My laptop isn't overheating and I have the latest drivers. Please help me!
