now i can do anything !
when i turne the computer on it goes to a blank screen can anyone walk me threw fixing it ?
ok we need alot more info about your computer, what you were doing when this happened, exactly what happened before and after to be able to help you at all...First: You have to specify if you have been connected some NEW component to your PC.

Second: Check if you have an USB drive connected to your PC.

Third: You have to tell what kind of machine do you have, ALSO, when starts the failure.

also, what is your computer configuration. Are you sure you did not accidentally disconnect cable from your monitor to your computer (assuming you have the desktop computer)

Most likely there is something wrong with the video card connection or with the video card itself. I had the same THING when turning on computer the monitor just goes "black", after replacing the video card everything was back to normal. I don't SEE how this could be caused by faulty drivers or SYSTEM software.
