Random Freezing with laptop

I'm getting occasional random freezes with UM 19.10 on my ASUS F505ZA with an AMD Ryzen 3 2200U processor. It seems to happen while watching video (though on brave it was in my github account), but I've had it with both Brave and Firefox browsers so it does not seem to be browser specific. I'm also not maxed out on resources as far as I can tell, its not just my mouse temporarily freezing like I have also reported. also I had similar freezes with elementary os, so I switched back to my regular os Ubuntu MATE and didn't have any issues for a while but now am getting them occasionally, just wondered if anybody had any ideas
