My desktop computer do not show any data on the monitor insted it only shows the blue light,what should I do?

what color is the light on the front of your monitor. is it different color when you see your desktop, my monitor is orange when off and blue when it's got a signal.

It depends on where the blue light is. Is the blue light on the monitor or on the computer tower? If it is on the monitor the monitor is having problems and needs to be serviced. If it is on the tower it could be an issue with the power supply.

Replace the monitor, is dead.

1. Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable.Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark.Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.If the new monitor you connected does not show anything either, proceed to Step 6.If the new monitor you connected does show information from your computer, proceed to Step 7.Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor.Chances are your original monitor is working fine.Test your original monitor with a monitor data cable that you know is working. It's possible that the monitor itself is working properly but it can't receive information from the computer because the cable that connects the monitor to the PC is no longer working.Note: If possible, test using the data cable from the monitor that you successfully tested with in Step 5. If not, purchase a replacement monitor data cable to test with.Note: The data cable on some older monitors are permanently connected to the monitor and are not replaceable. In these cases, you'll have to skip this step and proceed to Step 8 Replace the monitor.
