Tchad, first let me thank you for jumping in and offering to help figure this out. All ideas are absolutely welcome and very much appreciated, It really has become a problem for many. And not just Mint, Apparently some Ubuntu users are having the same issue with some hardware brands.

Let me share that HP has always had some proprietary quirks with hardware BIOS and it’s default firmware. For instance even if there is another OS installed, HP still always has it’s own hard coded default device boot loader and menu aside from just the BIOS setup boot order control. In fact this HP firmware control is primary over the BIOS setup and overrides it. So the HP proprietary firmware control over hardware is ever present aside from the BIOS it’s self.

And something I found with Win 10 is that it never really shuts completely down when you power it down. The only way to truly make it shut all the way off and unhook from all partial remaining windows control is to disable “fast startup”. And I’m not sure how it does this, but it will actually let you boot into Linux and still be running a few elements of that windows control in the background such as the hibernate time out and the fast startup. It never fully unhooks from windows even if you boot up in a different OS.

This is what I ran into with my Wife’s new HP laptop. Between the HP factory firmware retaining control over the motherboard and hardware, and the windows not fully shutting down in the background, it would run linux just fine as it should but it would freeze up like clockwork at around the same time frame every time we used it even with 18.3. I had to go shut off the fast startup and set everything in windows to “never” for all the power saving features in the windows.

This cured it and now it actually shuts windows all the way down from the background and runs linux with no more issues. I have disliked HP for years now because of some of their built in hard coded proprietary stuff like this, they have always added stuff like this that wasn’t really needed. And win 10... Well it speaks for it’s self.

I really do appreciate the link you shared and we need to try and see if disabling the suspend in linux will help. Because HP just might be one of those computer brands it mentions in that article that the feature has issues with. But like you, I first highly suspect a possible overheating issue with Windflier’s PC. While overall it might not appear to be getting too hot, it is happening after he has been running videos for awhile and may be directly associated with the graphics processing it’s self aside from the main CPU temp? I know HP is famous for running hotter than most, they have always had “right on the edge” heating problems.

It could be just a couple degrees difference in threshold from what Windows is deciding is too hot and what linux has decided is too hot. Windows might be allowing a slightly higher operating temp before self protection kicks in than the linux is. I had this happen on my current HP, when running videos it would overheat just a bit and shut down when on linux. But it didn’t freeze, it shutdown. I had to go and reconfigure the “thermald” to make it turn the fan speed higher slightly sooner than it was by default. It was waiting to long before increasing speed and by then it was too late and had gone over the critical threshold slightly.

I know one thing... It would be nice if some genius could find the time to build a “GUI” application for Linux like “SpeedFan” that is available for windows... If I had the skills I would have already done this. It is very very much needed for cases like my own with HP. Be nice to monitor sensors and adjust the fan/fans using an easy to use linux GUI application, especially for the average non-techy linux user. :)
