Q: MBP pro 15inch mid 2009 has random freezes, RAM issue?

Hello all,

my MBP 15 inch mid 2009 has been randomly freezing lately. Only a hard reboot will resolve the issue. I have already upgraded my HD to an SSD a while back and that has massively improved performance. I've been thinking about upgrading my RAM to 8GB, could that resolve the issue? The CleanMyMac monitor shows me that the RAM is often nearly fully used, at the moment I have 50MB free running a simple Excel file, Chrome, Slack, Mail and Calendar. I have included an Etresoft report for full disclosure
