Low FPS in all games all of a sudden, 100% GPU load

Hi

I used to be able to play games on my ancient laptop (i5-3210m, geforce 640m, windows 10) on low settings. Yesterday I've launched a game after a 10 days or so break and it was a mix of stuttering and slow-mo. I used fraps to check the fps and it was 10 fps in the menu and 13-14 in the actual game. GPU load is 99-100% even in the menu. Isn't it weird that i get higher fps ingame than in the menu? Launched another game and in that game i was getting low fps even during intros with all the corporate logos (like ''nvidia - the way it's meant to be played'').

What i've tried:

- Switching in the bios between nvidia optimus and dedicated only graphics

- Updating nvidia driver

- Reverting to the default nvidia driver that comes from windows update center

- Disabling/enabling vsync in game settings

- Reinstalling windows

None of that helped. I don't get BSODs or screen artifacts. Does anyone have any ideas what might be wrong?

Thanks

It's an ssd, when gpu is at 99-100% ssd is at 3-4%. SSD health is 100% according to Crystaldiskinfo.
