Alright, so this is what I've found.

You should be able to restore your deleted display adapter through the Acer eRecovery Management system.

You can access this system during the boot up process, which will bypass the need for the display adapter to load, by pressing the hot key (Alt + F10) which will start the Acer eRecovery Management system.

Reloading your display adapters from this system is your best option.

Let me know how it goes.

You should be able to go into Safe Mode. So do it from there. After going to Safe Mode, go to Computer Management and Device Manager to update the display driver.

Ask again, if you have any problems.
