Error Checking with Windows XP

Windows XP's error-checking computer maintenance tool can be found by clicking open My Computer, single-clicking the Local Disk icon with the right mouse button, and selecting Properties. Now single-click the Tools menu, and click the Error-Checking Button. In the dialog box that appears, chose whether you want the error checker to just scan for, or also fix system errors as it finds them, and then single-click the OK button. Your computer will reboot and the error checker will begin (note, this process takes a long time, so pick a time when you don't need the computer). Combining XPs error checker with a free PC checkup will greatly improve your computer's performance.
