I started to have low fps

At the beginning of this week I started to have low fps. I already formatted my pc 2x and nothing. I used to have 50-90 fps on the csgo low 720p but now I have 10-30 fps. The cpu and gpu are at normal temperatures. It affects all games like CSGO, Valorant, Minecraft, Overwatch…My laptop is a Lenovo Ideapad S145-15API. It has less than 1 year of life. I already installed the drivers i need.

Specs: CPU – Amd Athlon 300u / GPU (integrated) – Vega3 / Ram – 2x4GB 2400
