Adding more RAM is in-expensive but this is the first tweak you implement if you are experience a slower PC. This is will noticeably improve your system performance.
Nowadays, a home and office computer has to work multiple tasks. Most software have been specified the minimum amount of RAM needed to install and play. For example, Harry Potter And The Prisoner of Azkaban requires 256 MB. Computer also needs some RAM for background tasks as well as to run the game. Photo-editing software and web browsing also consume RAM. Some day suddenly your computer can't keep up.
When the more RAM is necessary
If the hard drive light is flickering most of the time, then it's probably time to install more memory. Suppose the hard drive is a filing cabinet where you store your documents, then memory or RAM (random ACCESS memory) is the table you work on. Clearly the table can be accessed more quickly than the filing cabinet.
How much RAM is in your PC
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 should see the amount of RAM.
How much RAM you need
The amount of RAM you need depends on the operating system you are using. For Windows 98, 128 MB to 256 MB is enough. Although, Windows XP works better with more RAM. However, for surfing the Internet and writing letters, 256 MB to 512 MB RAM is enough.
