Anyway, your question is too vague, and there is no such Windows XP error "High Memory Usage on Internet Explorer." If you get an error message please write down the exact message.
 

I am getting same message on my PC and the message pops up and then disappears before I can write it down.
 
Let's start with the basics. Win version - Home or Pro, Service pack - 2 or 3, CPU speed, RAM, IE version - 6,7 or 8, Connection - Dial-up, DSL, ?, Windows Update current, Antivirus type(s), Firewall(s), etc etc.
