Hi PirateAtFifyThree,

ISSUES:

1. Failing Hard Drive. Backup all your data immediately, then locate an Apple Store or AASP for further diagnostics: Mac Repair - Official Apple Support.
2. Runaway Process. Something is using a lot of resources. See what is using it. For more info, read here: View CPU activity in Activity Monitor on Mac - Apple Support.

The Failing Hard Drive is the main concern.

Cheers,

Jack

By chance do you have any third party anti virus, cleaning or any other third party "maintenance" apps installed on your Mac?
