If by "green activity light," you mean the hard drive light, it might be that the computer does not have sufficient memory and it is constantly using swap files on the hard drive instead of system memory. Adding memory is a good way to solve the problem. Go to Start -> Run and type:
. . . and hit enter. A window should open that will display information on your computer, such as how much physical memory you have and how much virtual memory you're using. How much memory you need depends on what you're running. But those older computers didn't have so many background memory hogs like firewalls, antivirus and antispyware programs running in the background.
I like to have at least 256 mb RAM on older computers, though they'll run on far less.
