Black screen with cursor (KSOD) in Windows 7, 8 Y 10

This is the problem where the screen turns black with only the cursor over it. When you turn on the PC, you get nothing but a black screen. This problem is known as KSOD (black screen of death). KSOD occurs when the login screen turns black or blank. In this point, the operating system is supposed to load the shell, but if for some reason it gets corrupted, permissions are corrupted or changed, will not be able to load the shell. Additionally, the problem may be due to a corrupted VGA driver or a corrupted boot environment. The good news is that this issue is software-based, so it can be fixed with a little troubleshooting.
