Randomized freezing in latest elementary OS

## Prerequisites
- [x] I have searched open and closed issues for duplicates.

## Describe the bug
In the latest ISO off the website (could also be previous ones, but I've only tested the newest), a fresh or already used elementary install seems to be freezing or crashing randomly during use of the system.

I believe this might have something to do with dedicated nvidia graphics, as this never happened on my Core 2-based machine that ran using integrated graphics.

PCs I've tested now:
i7-4730, GTX 1650: freezes
i3-550M, 9400M graphics: freezes
Core 2 Quad Q6600, intel gma graphics: doesn't freeze

There's an original reddit post [here](https://www.reddit.com/r/elementaryos/comments/ewf7wv/constant_randomized_freezing_in_elementary_os/), some other people had this issue too.

### To Reproduce
There's no real way to reproduce this. It seems to randomly freeze up and die from about 5-15 minutes since hitting the login.

### Expected behavior
The system should run fine with no freezes.

### Screenshots or screen recordings
N/A

### Logs
N/A at the moment, the system doesn't stay stable long enough to get anything done

## Platform Information
- OS: elementaryOS
- OS Version Hera 5.1
- i7-4790, 8GB ram, Nvidia GTX 1650, 500GB hdd

- [ ] I'm using the latest version from git that I've manually compiled
- [x] I'm using the latest released stable version

## Additional context
If something like music is playing in the background when it freezes up, the music will just stop. Cursor also gets stuck too and the only real way to recover from it is holding the PC's power button and turning it back on.
