MacBook Pro keeps freezing

Hiya

I have a problem with my 2015 MacBook Pro 13’ that has been happening for 2+ years.

It will run like normal for a couple of weeks, the randomly start to freeze. When it freezes the sound skips, and it either freezes on the screen I’m on or on a black screen, and a reboot is always required (if left for too long it automatically restarts itself anyway).

Once it starts doing this, it tends to continue I.e I will boot it up and within a few minutes it is frozen again. Eventually it will start working normally again but it usually takes at least a couple of days, if not a week. It is essentially unusable during this time as it freezes every time it is rebooted.

Is there a solution to this? I tried factory resetting but this did not help.

Thanks
