Improve your computer's speed and performance
You can increase the speed and performance of your hard drive by cleaning up wasted space using ScanDisk and Disk Defragmenter. Click Start, Programs, Accessories, System Tools, ScanDisk. Make sure it's pointed to your C: drive and click the check box for "Automatically fix errors." When it's finished, click Start, Programs, Accessories, System Tools, Disk Defragmenter. A note of caution: These programs run better if you're not running any other applications, and the first time can be time-consuming. It is recommended that you do this about once a month.
