Short answer: Check fuse, power supply, and make sure both the monitor and the PC are plugged in. It is possible that either your graphics card is dead or not inserted properly. However, it could also be the CPU or even the motherboard.
Longer answer: When you press power button of your PC, see if the little LED under the button is on. If not, then you should check the power supply, RAM and the CPU.
You can check the power supply fan to see if the power supply works. If that works, then check your processor and RAM in another CPU or get different RAM and processor and then try them with your PC one at a time. You can also try the power supply in another PC.
If the little LED under the power button is lit and the power supply fan is running, then check the video adapter is it built-in in or standalone if it is built-in then the problem may be in your monitor display. If the video card is standalone then check the video card in others PC or any other video card to your PC.
If your CD ROM is not on that is supply is off or not working then you must first make sure that the power supply is okay. So try it in another PC. If it is okay then turn to processor and RAM as told above.
The next thing to check is your CPU. It that doesn't work, then you should try the motherboard.
But before working out on your CPU you should check your monitor with a known working machine. Often, you don't even need to have the monitor attached to anything to be able to test it. Its light by the switch should be on, and the display may be lighter than when it is off. That shows the monitor is okay. Otherwise if there is an orange light then it may be consider in most computers that the monitor is not okay.
Monitor is not plugged in or monitor is not plugged in to computer
nothing can affect a computer
This depends on what computer and what monitor we are talking about. Back in the old days the monitor had no two way contact withthe comuter and controlled nothing. More current Monitors are plug and play so the monitor tells the computer what it is and how to talk to it. So to a very limited extent, yes. Then the touch screen monitors that are common now do control what happens inside the computer.
1. That was a really badly worded question, you didn't even ask anything. 2. You're monitor is either broken or a ribbon cable on the inside of your laptop is broken. Send it in for service.
Nothing, ionic compounds on cooling remain as they were.
Nothing happens.
When the computer is not processing anything at all. The computer light is on the monitor light is not but nothing is processing through the computer therefore no data is coming up on the monitor, not even the startup menu.
If nothing happens when you press the power button, make sure all the wires are connected. make sure that both the computer and the monitor are plugged into a power source. Also, make sure that the monitor is connected to the computer. If it still does not turn on, you might be having a problem with one of the components in your computer. At this point I would take it to a specialist and have them figure out what the problem might be.
It will be blank..nothing is saved to your moniter.
Go to a computer specialist!
Nothing.
Just selling the monitor can do no harm. Nothing is saved to the monitor itself, it is only a display device and will display data of the computer to which it is attached.
