Answer:
A. Corrupted or missing display driver
Explanation:
The most likely reason for this problem would be a corrupted or missing display driver. The display driver is in charge of grabbing the information from the graphic card and adjusting all the necessary settings so that all of the graphic card's power is able to be utilized. Missing or corrupt drivers can cause errors such as laggy display, wrong resolution/minimum resolution, missing display settings, etc. A graphic card failure on the other hand would show no image on the screen whatsoever when turning on the computer.
