Click the radial button next to "High Performance." Changing the power mode to high performance tells your computer to constantly use as much CPU as possible for all tasks.
Click the "Advanced" link next to "High Performance." Scroll down to the "Minimum CPU Usage" field. Ensure the value entered in this field is at least 50, if not 100. The value in this field represents the percentage of the CPU constantly in use by the computer. A value of 100 forces your computer to use all of its CPU power for any task performed. Click "OK" to exit the window and save your changes.
To restore your power settings to their default values, click the "Restore to Defaults" link in the Advanced portion of the Power Management window.
