Rarely do I come across a problem with a computer that I cannot diagnose, however when a computer has a black screen in windows it can stump me sometimes. A computer black screen on startup is a challenge for me and I always try to troubleshoot the problem manually, without using those fancy programs, because I believe it is the only way to learn.
There are two types of computer black screens that can appear in Windows. One where the computer will not boot up but you have a beep sequence sounding to let you know what the problem could be, and the other has nothing at all. No beeps, no cursor, no logo screen, and no choice to boot to safe mode or access the bios.
Look for and Try below:
When your computer has a black screen in Windows:
- When the computer will not boot up, it sounds like it is booting as the CPU fan is running and the lights are on. It also finds the CD ROM but it won’t boot from a CD either.
- Sometimes when you have a computer black screen on startup and the power switch light will be green and then turns to orange or amber. Everything is running.
- Everything seems to be running but you can’t see anything on the screen, not even a flashing cursor. Your black screen in Windows has occurred before the Windows logo screen.
