Q4os with Trinity desktop really needs little RAM and runs fast even on old devices. The desktop is a bit old-fashioned, but ok. You may also try lighter browsers, perhaps Palemoon.
But 4GB is actually not that little, almost all distros can run well with it, especially rather slim ones like Debian lxqt. maybe it’s really due to the hdd.
