this is probably one of the reasons for those freezes:
you have old nvidia gpu, which is no longer supported by manjaro and other distros…
you can install older kernels:
sudo mhwd-kernel -i linux54
sudo mhwd-kernel -i linux510
and try with them and see how it works…
or you can install the drivers manually by checking this topic:
another possible reason could be that you are on RAID:
instead of being on AHCI, you can switch to AHCI in bios, but if you are dual booting with windows, you will not be able to boot into windows after switching…
