I own an Acer W500, a tablet PC made a few years ago. It runs pretty well and I decided to upgrade it to Windows 10 just a few days ago. However, after upgrading, it ran into an issue where a black screen would appear after login, with a cursor.
What causes this issue? One might be drivers, and one might be Windows file explorer enhancements, such as OldNew Explorer. Another might be issues with monitor management, or that the system is doing a disk check.
What can be done? First get into Safe Mode. Press CTRL+ALT+DEL to get into a place where the system can be restarted, then press SHIFT+Power icon, then press Restart. This will bring up the troubleshooting menu.
For those that can get into safe mode, use this to uninstall any explorer enhancements or to update drivers.
For those with the check disk problem, it’s probably good to wait about an hour to see if the black screen will go away on its own.
For me, I was unable to get into safe mode since the safe mode boot screen would not recognize my USB keyboard. Anyway, I had already backed up all my data, so I used the troubleshooting menu to reset my PC (reinstall Windows).
Now, it works, although it is a little slower than on Windows 8, but the entire Windows system only takes up 10GB, vs the 15 with Windows 8 and 7.
Now to create a clean install…?
