I have a relatively new PC about four months old with a GTX 1060. Recently, I noticed significant FPS drops in games without any apparent issues. After checking my drivers, they seemed fine. I discovered that restarting the PC and powering it back on resolves the problem temporarily, though it reappears after a few days. I suspect the OS might be the cause since the graphics card appears to be functioning properly, so it could be the operating system affecting performance. Maybe just cleaning the PC would help.
