Maybe unrelated but worth a check maybe. Microsoft office click-to-run would just suddenly eat up half of my cpu utilization at random times and for no apparent reason, the only reason i knew it was happening is because I have my fans set on the more aggressive side and could hear them preparing for take off while I was doing something minimal like watching YouTube. It is possible to disable this but it turns back on anytime there is an update and i got annoyed with that so I just uninstalled Microsoft office and it hasn’t happened since.
