Question about Dell OptiPlex GX110 PC Desktop
The computer shows the fans functioning but no data is sent to the monitors. i have tried with different monitors but it still sends no signal of data. i have a feeling it may be a problem with the mother board.
The first thing to do is to pay attention for "beep" when your press the power button (or the reset button) to turn the computer on or reboot it. The beeps that a PC makes tells you a lot about the state of your computer. I couldn't quote for you the exact beeps to listen for, but your manual for your motherboard may tell you. Different beep pattersn tell you what is wrong with a computer.
I think for many common motherboards it is something like 4 beeps to tell you the graphics card has failed. Don't quote me, but that is at least along the lines of how it works if not the exact number.
If you're getting no display after starting your computer make sure you hear one beep. Then, listen for other activity. If you're computer has a floppy drive, listen for the 'floppy seek'. Otherwise, listen for hard drive activity. If it sounds as though there's activity along those lines but still no signal/display on the monitor perhaps check the cable between your PC and the monitor. Never hurts to just make sure the monitor is turned on of course.
If your monitor is on, and the cables are connected securely I wold restart the computer again and check for the beeps. I would be certain to count them and check the manual. Your graphics card may have failed if you hear abnormal beeps (more than one as one is usually the healthy indicator). If you hear no beeps then the PC is not even getting in as far as testing it's devices and could quite possibly be a motherboard failure.

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.
