Want to share my experience with this problem, I also posted this on reddit
I have read several post here and on other websites that CAM can cause a weird computer freeze/hang which stops any playing videos, cannot open any new apps, but the mouse can move and do some things, example open start menu, open task manager (which does not refresh) and only way to fix it is hard reset.
My experience starts about 6 months ago, when I built my PC brand new and it started to freeze/hang from day one. Because it was a new PC I wasnt going to reinstall windows again just to check if that was the culprit. I ran several benchmarks and stress tests, nothing wrong ever happened during that, temps and everything else fine. the Freeze always happened while watching youtube videos, but once happened when playing among us, but youtube was also running.
After several troubleshooting tests I just accepted it as something I had to live with, mostly because it never happened while I was doing anything important.
couple months passes, the freezes are happening every couple days or so (max 4 days) but they became part of the routine (again only while watching youtube). By chance I came across a windows feature (Reliability monitor) one day when I was just searching on different ways to troubleshoot windows 10. This showed me the dragon center services (from MSI) were crashing exactly the same time when these freezes were happening, so after deleting the services, and than eventually the entire dragon center I experienced the longest freeze free run of 4 days, on the 4th days, it froze, so as a trouble shooting step I reinstalled all my "monitoring apps" (MSI after burner, HWinfo, AND CAM) and made sure all traces of dragon center from MSI were gone.
After that no freezes for 2 weeks or so, only problem was I cannot control my RGB ram, so I install the Corsair iCUE to do so and on the same day I experience a freeze, further troubleshooting suggest some software conflict and this is the time I come across other post of people saying CAM is the culprit, so I uninstall iCUE, and my freezes are gone for two months...
Until last week, computer froze, same symptoms, now I know it is CAM allegedly, So after looking around I found liquidctl, While using this the computer works for 2 days just fine but the problem is fan speeds are fixed and LED light control is a nightmare. So I turn on CAM, very next day computer froze.
Now I am pretty sure its CAM, or at least its because of CAM, mainly due to other people have also isolated this specific software. but I am not giving up my fan and LED control this easy, so as troubleshooting step, I check for driver updates and all and come across my outdated chipset drives for AMD, tried installing it, but kept getting an error (This installer is intended to be deployed only on an AMD system. Existing installation as the requirement is not satisfied) turns out having SPACE in your user name causes the installer to bug out , and only way to install is to create an ADMIN account. I did that and today is the 7th day of no freezes.
So to conclude I cannot say for sure my freezes are due to CAM, but there is definitely some weird compatibility/bug that has some people annoyed, I will update this post if the freeze happens again.
TL;DR Struggled with computer freeze since building it, solved the problem once by reinstalling all monitoring software (maybe), and recently by updating my chipset drivers (7 days and counting, verdict still pending). Hope this helps someone.
