Hi Delirious11,
I review the procedure sent before and please, could execute the next steps, that has some differences:
- Enter WinRE
Before you enter safe mode, you need to enter the Windows Recovery Environment (winRE). To do this, you will repeatedly turn your device off, then on:
- Hold down the power button for 10 seconds to turn off your device.
- Press the power button again to turn on your device.
- On the first sign that Windows has started (for example, some devices show the manufacturer’s logo when restarting) hold down the power button for 10 seconds to turn off your device.
- Press the power button again to turn on your device.
- When Windows restarts, hold down the power button for 10 seconds to turn off your device.
- Press the power button again to turn on your device.
- Allow your device to fully restart. You will enter winRE.
- Now that you are in winRE, you will follow these steps to take you to safe mode:
- Windows Safe Mode
Choose an option screen in the Windows Recovery Environment.
- Click on the Troubleshoot option
- Click on the "Advanced options" option.
- Click on the Startup Settings option
- After your device restarts, you'll see a list of options. Select option 5 from the list or press F5 for Safe Mode with Networking
- Using the Device Manager disable Intel HD Graphics on Display Adapters
- Restart the PC and verify if the issue is fixed
If during the execution of the procedure appears again the black screen with dots, I suggest thinking in apply a Windows Repair Install (will need an ISO file) or the procedure for Windows Restore if you have some restore point.
I hope to help you. Please, tell me the results.
