Under some conditions, your computer may run slowly.
This behavior can occur for any of the following reasons:
- Programs may be started automatically when you start your computer. Programs that run when you start your computer typically run all the time; this uses a portion of your computer's system resources that cannot be used for any other task.
- You may be running a program that creates memory leaks. When you quit a program, the system resources that the program uses should be returned to the operating system. However, some programs do not return all of these resources, effectively "leaking" memory, and this can create a low system-resource state.
- Your computer may have a small or minimal amount of random access memory (RAM), or a slower central processing unit (CPU). For example, although Windows XP can run with a minimum of 64 megabytes (MB) of RAM, this amount of RAM may not be sufficient to maintain a high speed while you run one or more programs. Also, if your computer has only the minimum CPU requirements for Windows XP (300MHz or higher), it may not be sufficient to maintain a high speed while you run one or more programs.
