Hello,
It looks like the new Windows 10 version is not playing nice with your computer. From what we understand you only experience this issue on first boot since you mentioned that the problem does not occur when you shut down and restart your laptop.
If you are able to boot your computer to normal mode after starting in safe mode, then we suggest that you rollback your display driver. The newest and latest driver might not be fully compatible with the new Windows version. Here's how:
- Start Device Manager. To do this, press and hold (or right-click) the lower-left corner of the desktop, and then select Device Manager.
- Locate and right-click the display adapter driver, and then select Properties.
- Select the Driver tab, and then select Roll Back Driver.
- Check if the issue will persist when using an earlier display driver.
Additionally, some third-party antivirus software has been known to cause black screens. Removing the software won’t leave your PC unprotected, because Windows Defender Antivirus will kick in if no other antivirus software is running.
To rule out any software conflicts, let's perform a clean boot. When you start your computer in a clean boot state, it starts by using a minimal set of drivers and startup programs. This troubleshooting method is designed to isolate if this issue is caused by a startup program or service. For steps on how to perform a clean boot, you can refer to the following link: How to perform a clean boot in Windows. After you have finished troubleshooting, you may refer to the Reset the computer to start normally after clean boot troubleshooting section to reset the computer to start normally.
Let us know how it goes so we can assist you further.
