Try to re install your operating system you can't troubleshoot it if your video card is working a problem like that can be troubleshoot if you can't see any video on the screen you have said that it is working at the start up to the welcome screen so it means there's nothing wrong with your video card and monitor.
Hi andrew,
in that case you need a installation disc of your operating system to repair.
if its vista or windows 7. then you can try start-up repair. by selecting at startup.
to do so. start hitting F8 key as soon as you press the power button.
you will be prompted for advanced boot options.
there you can select startup repair.
you can try system restore as well.
your computer will start working.

Sorry to hear about your problem. I would be happy to help. I just need a little more information first. What model laptop? What operating system? What were some of the last things you were doing before this happened?
My computer model is a Dell inspiron 560MT, operating system windows 7.
The last thing i was doing was using a program called registry booster 2. It may have been that and i cleared 314 registry errors, then restarted and then i just had the black screen and white cursor.
I've managed to get the system restore and start up repair but that ended in failure.
