G5 Screen Freeze

[Falict]

Hello. My DELL G5 15 keeps freezing at random moments.
This labtop is around 2 months old and it just keeps freezing when i'm using it.
I tried factory resetting, and installing windows 10 again. Is this a software issue or hardware issue?
Are there any diagnostic programs i can try?
Also, when it's frozen, i just have to close the lid and open it backup and log in. THen it goes back to normal.
When it is frozen, my mouse stays put, everything literally just freezes.

Help!

If you aren't doing to much at once, which can cause freezing, and it is that new, I would contact the manufacturer, as it is still under warranty.
