I don't know if this is the area to be posting this but...

While I was using windows my monitor and sound kept turning off (the monitor went into power save) the computer would still be running though. The only way to remedy would be to turn the computer off and on again. But now, when I turn the computer on, the monitor won't turn on at all! What can I do? I can't even GET into safe mode or anything like that. I don't think its a monitor or GRAPHICS card problem because the sound would go off as well. I don't know if it can be a virus because windows hasn't even booted up before the monitor doesn't come on. Help! What can I do?Begin by testing your monitor in the following manner:

unplug monitor from computer. get another monitor (borrow one if you have to) and another computer (borrow one if you have to) and follow these steps:

1) plug your monitor into the other computer.
2) plug the other monitor into your computer.
3) turn on both computers and both monitors.
4) Does your monitor work on the other machine? Does the other monitor work on your machine?
5) Report back to us. Be sure to answer the questions in step 4.

How is your computer connected to the power grid?

What do you mean about the power grid? It's just...plugged in...Can you please supply system info......monitor is....PC is a laptop/desktop/tower.make model..self built or shop puchase...operating system is?What ELSE is plugged in and how.

The tower is an Advent 3412 and the monitor is an LG 570LS.

The monitor, SPEAKERS and tower were all plugged into the same extension splitter thing but i moved the tower to a separate socket of its own and it still doesn't work...

What component do you think is causing the problem and how can I fix it?I would  check the power settings/control panel........click the power icon....always on >>>..and see if the settings are set to>> never.........in all the boxes.......and i would run a virus scan just to make sure. If it was my pc.I can't do that though, I can't get into windows or anything, the monitor won't turn on any more...check the fuse from the mains plug..........5amp should be..this can be checked........even if the monitor is not connected to a pc........it will display a  message on the screen.........if this monitor is under warrenty then send it back.....if it displays nothing on the screen..........
