Did a reset to factory settings on so’s g16 and now it just freezes

My so had a completely full laptop and it kept lagging so we did a reset to factory settings and now it keeps freezing anytime they try to play any games. And it’s loading extremely slow even slower than when it had a couple gb free space left. It is about 80 degrees in the apartment but they have a few fans blowing toward the laptop.

When I did it for my g14 it worked fine I’ve never factory reset a laptop and had it do this

Any ideas?
