Very unstable system

I put manjaro on my old laptop and i loved it so i decided to install it on my main system but the system is very unstable and just locks up sometimes and this sucks. I have a nvidia gtx 1060 3gb is there a driver i can install to make my system more stable?

Can you report the output of:

inxi inxi --admin --verbosity=7 --filter --no-host --width
sudo mhwd --listinstalled
sudo journalctl --boot=0 --prioroty=4
