Recently, every time I turn on my computer, several "System Error" pop-up window appear, telling me that different names of DLL files are missing, causing the program to fail to run. I don't know exactly what program is not running, but the page for me to log in to my account and enter the pin code or my fingerprint cannot pop up. The last time I turn it on till now, the computer screen even went black. I want to know if there is a problem with my system and how to solve it?
See if this assists you with your Repair options.
You can use the power button to restart your computer three times. This will start the Windows Recovery Environment.
