My iMac 21.5", Late 2009, is running slowly and am getting the beachball. Processor 3.06 GHz Intel Core 2 Duo, Memory 4 GB 1067

My iMac 21.5", Late 2009 is running in macOS High Sierra V10.13.5, Processor 3.06 GHz Intel Core 2 Duo, Memory 4 GB 1067 , MHz DDR3. When the beachball starts spinning I have to just shut it down and re-boot.

I first tried to reboot several times in SafeMode but it wouldn't open in SafeMode. Then ran EtreCheck and the report is as follows. Is it worth it at this point to configure Time Machine and upgrade my RAM?

Any other suggestions? Thank you for your time.
