emachine monitor keeps shutting off

We get this a lot. There is no need to attach files until we ask. Often we can help you without a long system info file.

Lets start fresh and tell me what is going on and we will see if we can help you. Odds are this is a driver issue or a power setting.

 

O.K lets do the steps assuming you do not have some sort of hardware failure underway. No signal means just that. The monitor is losing the signal somewhere between your video card and the screen narrowing down what to look at.

It is possible that you have a cable problem:

Shut off the computer.
Loosen the cables on the monitor and video card and reconnect them firmly. Make sure the ports you are bolting into have not loosened up.
Optional: If the monitor and computer can be connected a different way (HDMI, DVI) and you have access to cables this may be something you need to try later.

Loose video card:

Take cover off the computer. Remove the video card (assuming it is a video card and not onboard video) and clean the connections lightly with a basic pencil eraser. Reseat it firmly.


If these do not work you start to get into a spot where having extra parts (computer tech for example) around really helps you diagnose the problem. It helps if you know you can duplicate the problem every time as well. In this case, I would borrow a monitor from someone and see if it continues. If it does not, then your monitor has failed. If it continues we have to consider a bad video card.

 

Yes, they are. They have multiple pins either white or blue. Occasionally HDMI like you might use on a television. You have 2 cables coming from your monitor; power and video connection so it's the one that does not plug into the wall. It could simply be loose. Follow that cable to the video card and make sure that is also tight.

If it is an Emachine computer odds are it is what is called onboard video. This means it is built into the motherboard of the computer and you will not be able to remove the video card. How to tell? In the back of your computer, usually towards the bottom is a bunch of rectangular slots. If the video goes in there, it is a removeable video card. If the video card plugs in near the mouse, keyboard and everything else, it is onboard.
