What parts to buy a computer for better performance?

Question

motherboards

Hello! The computer was assembled a long time ago, it used to fly, but now it slows down even without any programs, just working with some folders and word files. Browser, 1s version 8.2 and other programs (the computer is not for games) barely work, the computer just works TERRIBLY, sometimes you can go have time to drink tea while it loads. Actually, who can advise what to buy from the details to speed up the PC for work? Games will not be installed on this PC, so it is advisable to spend a minimum. Below are screenshots of the computer (if something is missing, write, I'll take a screenshot).
