How to speed up your computer

I had made something similar like this before. It was my "Lag Help Guide" on my guild forum. (: I have some extra things you can include:

Virtual Memory
Virtual memory acts as extra RAM for your computer, used off your hard drive.
My Computer -> Control Panel -> Performance and Maintence -> System -> Advance -> Performance [Settings...] -> Advanced Tab -> Virtual Memory [Change]

Depending on the free space of your HD, how much to set. Your computer will give you a recommended amount at the bottom of the box, which is what it most likely has allocated. If your computer has the HD space, double the recommended amount as your min, and multiply that amount by 1.5 to set the max amount. Once finished, press OK.

Also, remember... A clean desktop is a happy desktop. The less items on there, the faster it will be when you minimize and switch windows.
