My new laptop keeps randomly freezing for a few seconds during normal use
That sounds annoying and not what you want from a new laptop. A few seconds of freezing can be software related or due to heat and background apps.
Could be software misbehavior or a stubborn driver after an update. Try a clean boot to test with minimal startup programs and see if the freezes stop.
In my experience a similar freeze showed up after a big update. A memory test and checking temps helped pinpoint the issue and fix it.
If it keeps happening you should reach out to support or a repair under warranty rather than living with it while it fights you.
