To speed up your computer, you need a proper amount of RAM available on your system.(step by step guide)
Determine how much RAM you have and how much you need
Before you buy anything, you need to know how much memory you have and what type of memory to buy.
Find out how much RAM your computer has
You can find out how much RAM is installed in your computer in two ways. You can open the System Information dialog box to see the installed physical memory (RAM), or you can go to Control Panel.
To open System Information, click Start, click All Programs, click Accessories, click System Tools, and then click System Information. In the left pane, select System Summary. The Installed System Memory (RAM) entry in the list tells you how much RAM your computer has.
The Installed Physical Memory (RAM) entry in the System Information list tells you how much RAM your computer has.
Go to Control Panel in your version of the Windows Operating system to find out how much RAM your computer has:
In Windows XP, go to the Start menu, click Settings, and then click Control Panel. Click System and then select the General tab. At the bottom of the page you will see the amount of RAM.
Find out how much RAM you need
Most games specify the minimum amount of RAM you need to install and play. For example, Harry Potter and the Prisoner of Azkaban requires 256 megabytes (MB). This amount includes RAM that the computer needs to do its own background work in addition to running the game.
The amount of RAM you need depends on the operating system you are using. For systems running Windows 7, Windows Vista, or Windows XP, you should have the minimum recommended amount, but more can be better, depending on your needs. If you just use your PC for surfing the Internet and writing letters, you may need only the minimum amount of RAM required to run the version of Windows you have installed on your computer.
