There are so many different types of black screen problems and there are so many different types of solutions to go with it. I will list a few things that might be happening to you:
- All the lights on on your computer but all you see is a black screen. You can hear the fan running in the background and it seems like your computer is working, except for you can't see anything.
- Your computer tries to load into Windows, and you login to see a black screen.
- Your computer does not even load Windows and goes to a black screen and then restarts over and over again.
- You start your computer and it looks like it is starting normally but get stuck on a black screen with a flashing cursor and does not go any further.
Sometimes to fix boot errors you can buy a post diagnostic card like the one the professionals use that will tell you, most of the time, where the problem lies.
This is a very handy piece of hardware to have around if you are into fixing computers. It is often helped me get out of my black screen problem in a matter of minutes.
However if you do not have one of these post diagnostic cards available then here is a number one article on how to troubleshoot a black screen.
