Hi Mitesh,
Based on the details provided on this thread, we have one additional question for you. Are you using any restore software (ex: Deep Freeze software and Reboot Restore RX) on your computer? It is also possible that the issue is due to one of the running application on your computer's background. We recommend that you perform a **Clean Boot**and check if there are changes.
Note: Reset the computer back to Normal Mode once you are done with the troubleshooting by following the section "How to reset the computer to start normally after clean boot troubleshooting" from the same article.
Update us on how it goes.
Regards.
