If you ARE ABLE to get any kind of light on your monitor showing that it's got power running to it, try this.
1. Try your monitor on someone else's computer.
2. If you can't do that easily, try pushing the monitor button in for half a minute or so, and then trying it again.
3. If that doesn't work, turn your computer off.
4. Now unplug it! Don't forget this step please.
5. Remove your graphics card if it isn't built into the motherboard.
6. Put your graphics card back in again, carefully.
7. Plug the cables in again, making very sure they are all in the right slots and that they are hooked in soundly.
8. Plug your computer back in.
9. Turn it on again.
You can try skipping 5 and 6 and just going through the other procedures first if you like, and then if that doesn't work, go through the longer process starting at number 1 again, but this time including with steps 5 and 6.
If your graphics card is removable and fits into another slot, you might even want to try that. If you have already tried that and none of those procedures worked, you might want to buy another graphics card from a dealer (preferably one who will allow you to return it within a few days), to see if that solves the problem. Make sure you look at the back of it before buying it to ensure it has all of the plug-ins you need and/or want.
10. If you can't see that there's any power going to it at all and can't feel any heat coming from it after it's been on for 10 minutes, then you know the problem is solely with the monitor and not with anything else so you may have to talk to a technician in person and ask if he feels it's worth repairing.
Note that whenever you plug and unplug the main cable that runs from your computer to your monitor, it's best to shut your system down first to prevent sparks and/or damage to a card or even to a major piece of equipment. I also prefer to unplug my own equipment entirely during thunderstorms because I've known a few people who have blown their entire motherboards this way.
