Hall.dll file is missing and black screen

Question:

Hello, I have an Acer laptop , suddenly the PC screen is completely black and noting was displayed, but the keyboard is on, so I can make sure that the windows is still working, I tried to restart the computer, then the system reported that there was a dll file missing, but the information disappeared soon, so I can’t remember the missing file name exactly, The file maybe is Hall.dll? ¬†What should I do ? A lot of people online recommend some tips like reinstall windows to recovery the system, this could solve this problem, but all methods seem to require a CD-ROM, but I don’t have any CD or optical disc drive, is there any other solution to solve this problem?
