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.

Either your monitor or video card is going bad. Try a different monitor to isolate the problem. If you attach a different monitor and it does the same thing, then your video card is going bad. if you attach a different monitor and it does not have the problem, then your monitor is going bad.
Connect the monitor to a different computer, to see if the monitor works at all.
Connect a different monitor to your computer, to see if your computer really is "sending" a video-signal through the "data" cable. If not, then either the data-cable or the video-card inside the computer is faulty.
Try connecting the monitor to a different computer, e.g., a laptop.
The power-cord to the monitor seems to be OK.
Check the "data" cable between the monitor and the computer -- try a different cable.
With the monitor turned on, restart your computer, and watch the monitor. The computer should show some start-up messages (white text over black background), followed by the Windows "splash" screen. If it does, the monitor is working correctly.
sounds like an overheating problem. you can try blowing out the back of the monitor, or putting a fan close to it. If it is really dirty it will shut itself off so as to not get damaged. is it crt, or lcd?
Colours on the screen are generated by "mixing" the 3 primary colours.
Of the primary colours is RED.
So, your LCD monitor is not receiving signals from your computer,
specifying the other two primary colours.
Check the data-cable between your computer and your monitor,
to ensure that the connections are tight at both ends.
Try a different data-cable.
Try your monitor on a different computer, with two different data-cables.
Try a different monitor on your computer.
It could be the video-card inside your computer is failing to "send" one or two of the primary colours.
Yellow led light means the monitor is in 'sleep' mode. There is no signal being sent from whatever it's connected to. If it's a computer, try checking the connection(s), make sure it's not come lose inside the computer, try if you can the computer on a different monitor or the monitor on a different computer.
