Nvidia card causing system to lag and eventually freeze

After a couple minutes to a couple hours my system severely lags and becomes very unresponsive before eventually freezing and needing to be forced off. The only way to fix it is to remove my NVIDIA card. I don’t know if it’s a memory leak or what. I can’t find any way to diagnose what’s going on. I put the gpu in my secondary computer which has windows on it and it works okay (though it may do the same thing, just after several days instead). I do believe I chose proprietary drivers when installing manjaro for the first time (the installer gets stuck at 90-something percent on my main rig so I had to temporarily take out the ssd to and put it my other one just to install manjaro which happened to have that same gpu at the time).

Here’s my system info
