What causes computer screen to suddenly go black?

Answer 1

AnswerThe are two possible reasons:

1. If you are not using it for a period of time there is a setting to turn off your monitor. It is located in control panel >> Display >> Screen Saver >> Power. In there you can set the screen to turn off if you haven't been on your computer for a certain amount of time.
2. If you are using your computer and the screen goes black the it sounds like the screen is going bad and will need replaced. Yes even if this is a new monitor it could happen. Don't forget if it is new there is a warranty.

Answer 2

First, make sure the screen is plugged in. Does the screen power indicator light come on?

Second, make sure the screen data cable is plugged into the computer.

Third, is the computer power supply working? Many desktop PCs have a fan in the power supply. If the fan isn't turning, the power supply is dead and must be replaced.

Troubleshooting gets more complicated after these three steps.

Answer 3

Random theories as to what the problem is online might be of little use to you. The best avenue to take will be to have a technician take a look at it. It's common for the standby switch to go bad on HP laptops. This causes the computer to think the lid is still closed even when it's turned on and opened. Or, it could be that the monitor simply went bad. Only way to know for sure is to have it checked by the OEM, or by a licensed computer technician.

Answer 4

Well if you leave your computer for awhile it's connection dies down and goes black until you move the mouse or go back on and do what you are doing.....
