"No signal found" is a generic display from a monitor that is not receiving a signal from the input cable. Your tower, however, may or may not be functioning. If you have another source to connect the monitor to (laptop or other PC) you can try that. Most monitors have a "menu" button. You could press that to see if a menu is displayed on the monitor, That will indicate that the monitor is working as a stand-alone. It will also indicate which input source is being used. If the input source is incorrect, then no signal is being received from the incorrect source. As far as the tower is concerned, the are a myriad of causes for no signal to the monitor. It could be unbootable due to a hardware failure at the mainboard level or the power supply. If you hear a single beep then the main board has passed it's diagnostic testing successfully (memory is ok, chips and CPU are ok). If you hear more than a single beep, the main board is having a problem. If a single beep occurs, them most likely it is the graphics controller. any other failure would be displayed on the monitor. If the graphics controller is on the main board, then you will need to install a new graphics card, bypassing the main board's controller. Was this a working system at one time?

The beeps are probably BIOS beep error codes. Through a series of long and short beeps the computer communicates computer problems that occur early in the startup processes. It's likely the problem isn't your monitor but something in your computer box itself. If you can tell us what the pattern is we can start diagnosing your problem. We'll also need to know the manufacturers name, the specific model computer you have and what operating system you are running.

Do you have two video outputs on your PC ie. one on the motherboard adn a separately installed card maybe? If you do you need to set the BIOS so that it uses the AGP/PCIE video card and not the 'onboard'. Try the onbopard vodeo card first to see if you get a signal there.
If you do NOT have two video outputs, and you can not see a signal then you may have a prblem wiht your monitor itself. Is this a known working monitor to start with?
SOURCE: We are getting a No Signal on our monitor,
it should be motherboard problem.
try to check it nearby service centers
are you able to hear any beep sounds

This could be an issue of a video card gone bad. I have experienced the same issue firsthand. This could also mean that no RAM is installed. If you have been using this computer previously, the second option is probably not even an option.
If you have another computer available, please try plugging the monitor in to that machine to test. If it works, your Video Card is more than likely toast.
But not to worry, you should be able to find a new card for that machine. I believe it will be a PCI Video Card, which may run you anywhere from $20-$100 depending on what you purchase. Please consult with eMachines before ordering a new card. Some will not work with your machine.
I hope this helps you out. Have a great day and please don't hesitate to ask any further questions regarding this issue.

Go to start, control panel, device manager, display adapter, right click and update the drivers. If that doesn't do the trick, Google for the display adapter on line and download the new one....
