You may search for lightweight and fast linux / distro for slow / old computer.
There are few available, but you may need to test which one more suitable for you.

Zorin Lite - not quite lite. Slow open youtube, interface was slow when use the start menu search.
Linux Mint XFCE - very well polished interface, much more responsive than Zorin. youtube browsing was faster with chromium but it keeps asking for keyring.
Lubuntu - interface looks very dated, doesn't even ship with good wallpaper. Use less resources compared to Mint XFCE and faster too. Chromium installation from the Discovery software manager was in snap package, didn't ask me for keyring. Stock bluetooth manager is horrible.
Next will try Peppermint OS, MX Linux and Ubuntu MATE.
