Cleaning Your Hard Drive to Improve System Performance

If the hard drive is full of unnecessary files, it can cause the computer to have slow performance. Typically, a hard drive with less than 20% free space will run slowly. "Cleaning" the hard drive by reducing the number of files may help improve performance.

To learn how to "clean" your computer's hard disk drive, refer to the following Microsoft Help and How-to article, "Delete Files Using Disk Cleanup".

General Troubleshooting for Slow Performance

To troubleshoot slow performance on your computer, the following articles are available from the Microsoft Knowledge Base:
950684 How to troubleshoot performance issues during startup in Windows Vista
950685 How to troubleshoot performance issues in Windows Vista
950686 How to troubleshoot performance issues with standby, hibernate, and resume in Windows Vista"

Upgrade Memory to Improve Slow Performance

If the computer is still running slowly after ruling out malware, recent software installations, and inadequate hard disk space, the problem may likely be a hardware issue.

Consider upgrading the computer memory. 512 MB is adequate for basic Windows usage. Memory-intensive tasks such as games, media applications, or productivity software, often require more memory.

Contact your computer manufacturer or a computer technician for more information on how to purchase and install more RAM memory for your computer.
