Here is a tip, if you are running Microsoft Windows XP, press CTRL+ALT+
DEL at the same time. Click on Task Manager. Select the performance Tab. Take a look at your total, and available memory in the Physical memory quadrant of the window. If your available memory is 20 percent or less of what your total memory is, it is time to take a look at your computer. Either you have a lot of applications open, not enough memory, or some combination of the two. In any case if you are using more than 80 percent of your available resources, then your computer will run inefficiently.Here is another tip. When you setup a new computer, setup two accounts, the first being an administrative account that you can use to install software, and a Power user account to use for your daily activities. This will prevent spyware from easily installing on your computer.
