Hi Crazy Legs
You are running a fair number of processes. If you can lose a few it may well help speed things up. You should disable some of your uneccessary start up programs. These are often things like assistant and help programs, or pc health monitors (not the anti spyware ones though!). Your 703MB of RAM might not be enough for your system to cope with XP and some of your applications. Try to bring this up to at least 1GB. You can never have too much memory! I run antivirus checks daily. Once a week is not very safe. Have you tried the free AVG antivirus program? This is easy to schedule, and PC Advisor often includes this program on their monthly disk. Try running an alternative web browser (like Firefox). There may well be a problem with your IE.
