My computer is running very slow and I know the reason is because too much stuff is running in the background. I am running Windows XP SP2, AMD Athlon, 2.17 GHz, 512 RAM. How do I know which programs/process to prevent from starting when my computer starts up? I know of a few I can eliminate, but don't know what many of them are. I know how to go to START/Run/msconfig and disable some of the start up processes. I just am unsure which ones to eliminate. I guess maybe a better question would be which processes do I need to make sure are running for my computer to work properly? If you can help, I would appreciate it. Thanks.
