Are you sure it doesn't say "Attention no signal check input signal connection"? This error message is displayed by the monitor when it does not detect an input signal. The PC is NOT sending a signal to the monitor. Check your cable connections - then you might remove the video card and replace it. (with the PC unplugged). Just about anything past this stage requires a PC technician to fix. Good Luck

Xpcman,

thank you for your help. You are right, it is "no" not "on".

I have checked the connections and they seem to be okay. where would the video card be and what does it look like?

I assume that this is a desktop PC and not a laptop. (if it's a laptop - take it in for repair - there is nothing you can do)
Trace the video cable back to the PC. The cable can be plugged into two things:
1. a socket on the motherboard near where the keyboard and mouse sockets are
2. a socket on a video card this is in turn plugged into the motherboard (removed from the area of the other sockets).

If you have the second configuration you can remove the case cover - remove the monitor cable - remove the screw holding the video card - remove the video card - dust it off - replace card - reverse the steps and reassemble the PC.
Restart the PC.

If this doesn't work then it's time to take the PC to a repair shop.

Good Luck

Hello again xpcman,

It seems like the video card is integrated in motherboard. It is Elitegroup Mainboard. I have attached the link for specs.

What do you suggest?? Thank you in advance.

Jay

I would test the monitor with another computer and test your computer with a different monitor. If the monitor proves to be good you are dealing with a dead video chip on the motherboard or a dead motherboard. You could have a repair shop take a look - one option might be to add a video card to the computer.
