How to Speed Up CPU Performance

By Justin A. Mann

CPUs are small microprocessors installed inside a computer. A CPU primarily performs numerous calculations per second for the computer. The amount of processes and calculations performed per second is the speed of the CPU. Increasing the speed at which the CPU performs is done by adjusting internal computer power settings, defragmenting the computer's hard drive, and eliminating any high-intensity processes that are not needed. All of these tasks are done through the computer's menus and require no physical handling of the CPU.

Step 1

Click the Windows Start icon and then the "Control Panel" option. Click the "Power Management" option. Change your computer's power setting to either "High Performance" or "Balanced." Power management options may not be available for older desktop computer models.

Step 2

Click "Start" and type "Disk Defrag" into the search bar. Click the "Disk Defrag" program and choose the appropriate hard drive, generally "C." Click OK to begin the defrag process. Performing a defragmentation on your primary hard drive cleans up fragmented files and allows your processor to access data faster and more efficiently.

Step 3

Enter the Task Manager by simultaneously holding the "Control," "Alt" and "Delete" keys. Click the "Processes" tab and sort the process by "CPU Usage." Examine the highest CPU intensive processes and determine if they can be closed. Processes such as chat programs, Windows Sidebar and game programs hog CPU power and can be closed to increase CPU performance.

Tips & Warnings

  • If you delete a vital Windows process, restart your computer. Restarting your computer reinstates the vital processes that were closed.
