How to add more muscle to my computer? (Resolved)

Added: Thanks for the help guys! :) I went to services.msc and tweaked some stuff. I've bought 1GB of RAM and (nervously) installed it myself XD Everything is looking good! I'll buy another stick next month when I have extra dough :D Again thank you to all your advice!



Hi everyone :D So I've been thinking it may be time to upgrade my PC. I always open a lot of programs at once when I do work. My PC has been great at handling it my abuse to it. I think it could use a little more muscle :D (Like my Humboys!). Now, how do I add more muscle to my PC? :O

So, I head over to the control panel and check on my System Properties:

System:
Microsoft Windows XP
Home Edition
Version 2002
Service Pack 2

Computer:
Intel(R)
Pentium(R) 4 CPU 2.93GHz
2.93 GHz, 760 of RAM

Much thanks to those who are willing to help! :)
