3. Click the "Startup" tab,click "Disable All" and click "OK".

4. Restart the computer and test the issue.


Note: Clean Boot is a troubleshooting step. If some programs have been disabled,we can re-enable them later. If you see the System Configuration Utility,check the box of "Don't show this message" and then click "OK".


Please monitor the system in the Clean Boot environment. If the problem does not occur,it indicates that the problem is related to one application or service we have disabled. You may use the MSCONFIG tool again to re-enable the disabled item one by one to find out the culprit.
