Question I need help

[Xenenxa]

So I know my laptop isn't for gaming, but I have this laptop

IdeaPad 1 Series | Affordable Personal Laptops

Ideapad 1 series laptops are built for productivity, but priced for accessibility.

Anyway so i upgraded to 8gb ram around 6 monts ago and it was fine i could run cs:go at 60 fps no problem and suddenly around a month ago i recived insane frame drops in every game it came to a poin that i couldnt run roblox at lowest settings and i re-installed my windows my graphic drivers are up to date only thing that i havent changed is thermal paste i boght this laptop back in 2017 and never changed thermal paste on it. So it may be it but it just seems my pc isnt using its full potential when i am running cs it is only using like 40% of the cpu but priority in task manager is set to high. If u have any advice I would appreciate it.

My specs are:
Intel i3 5005u
Nvidia geforce 920m
8gb kingstone 1666mhz ram
1tb hdd

CPU often isn't pegged while playing computer games. It's probably twiddling its thumbs, waiting for the 920m to get its work done. Do you know how to check your GPU temperature?
