After playing a while in some games like CS:GO, Black Desert, Tales of Zestiria etc my computer loses half the performance.

After playing like 15 or 30 min this is what happens:

-CS:GO: I still get 60 fps because that game doesn't require that much power, but I still get freezes, the same as other games when the fps drops drastically.

-Black Desert: My screen freezes for a second and then the game start running to 15/25 fps from 60.

-Tales of Zestiria: Runs at 30 fps from 60.

Restarting Windows fixes the problem temporary but if I start playing again for while, the same thing will happen. Also, if I lower the graphics in Black Desert I can get 60 fps, that's why I think the PC is lowering the performance for some reason, all this is happening suddenly, I don't remember doing anything weird.

CPU temperature seems to be ok, 75º max.
GPU 60º max

What is causing the low performance? Sorry for my english in case if I had wrote something wrong or hard to understand.
