Hardware installation (continued)
To install or uninstall a device driver, you must be logged in with administrative
privileges. If you need to switch users, click the Start button, click the Arrow button next
to Shut Down, and then click Switch User. Choose a user with administrative
privileges.
To resolve a device conflict, you may need to disable one of the devices or uninstall an
old device driver:
1. Click the Start button.
2. Type Device Manager into the Start Search box, and then click Device
Manager to open the Device Manager window.
3. Click the plus sign (+) next to the problem device and check for an exclamation
point in a yellow circle near the device icon. The exclamation point means there is
a device conflict or problem with the device. Exclamation points do not always
appear when a device is not working properly.
4. If you have removed a hardware device, but the device driver is still listed in the
Device Manager, this may be causing the device conflict. To uninstall the old driver
so that the new device driver works properly, right-click the device, click Uninstall,
and then click OK.
5. Right-click the name of the device, and then select Properties.
6. Click the General tab to see whether your device is enabled and working properly.
If it is available, click the Troubleshoot button, and follow the on-screen
instructions in the device troubleshooter wizard.
7. Restart the computer. Click the Start button, click the Arrow button next to Shut
Down, and then click Restart.

Possible solution
This happens when the processor is automatically running in a lower power state,
because the applications running do not require the maximum processing power.
Verify that your system contains the processor you purchased. To verify, click the Start
button, right-click Computer, click Properties, and under the General tab check the
processor installed on your system.
If you created multiple user accounts on your computer, ensure other users are not
logged in. If there are multiple users logged in simultaneously, system resources must
be shared among them.
