Suggestoin 4:
=====================
We may start the problematic computer in safe mode to see if this issue
occurs.The steps to boot into safe mode are as below:
Safe Mode loads a minimally protected-mode configuration, disabling Windows
device drivers and using the standard VGA display adapter.
1. Restart the computer.
2. Keep pressing F8 key until the Windows Startup menu appears.
3. Choose the Safe Mode with Network, and press Enter.
Note: Some third party applications and some hardware device cannot be used
during Safe Mode. You will temporarily be unable to connect to the Internet
temporarily while in Safe Mode.
If this issue disappears in safe mode, I suspect that it is related to some
third-party services or programs. We may use Clean Boot to eliminate third
party interference. To boot into Clean Boot environment:
1. Click Start, click Run, type "msconfig" (without the quotation marks) in
the Open box, and then click OK.
2. In the Startup tab, click the "Disable All" button.
3. In the Services tab, check the "Hide All Microsoft Services" checkbox,
and then click the "Disable All" button.
4. Click OK and restart your computer.
