Normally that is because the monitor is not plugged in. Check if it is well connected. If it is well connected, try another monitor. If it does the same thing again, come back here for more info. Be sure to explain everything that happens when you start your PC, like if there are beep patterns that could indicate anything. Does your PC make one beep at startup? Does you PC stay on?
Check for the latest video drivers (for monitor) & re-install. "plug-n-play" is sometimes called PlugNPray because some monitors just won't work with some system configurations.. no matter what you do. :sad:
If that doesn't work..
exchange your monitor for a different brand.
Hoope this helps ;)
If you are sure this monitor works, shows blank at startup and you get one beep, the chances are that your video display circuitry is defective. Your video card is probably a dud. If you can, try another card in your computer.
Im a total noob about computers but here is wot i have experienced with my system. I was playing a game and suddenly every thing went of on my computer and i got no signal on my screen so initialy i unpluged the monitor cable and replugged it back in and still didnt work altho i had power to my fans and there was a beep. In the end it turned out that my PSU had blown but i was still getting little power just to my fans and lights i changed my psu for a bigger wattage to 550 watt and sure enuff every thing came back on maybe u could have overloaded your psu i really dont know but have u heard about something called a D-Bracket it has lights on and displays certain sequences which show a diagnostic of your start up to show u wots functioning properly hope this helps :)
no signal.. could be the ram.. switch the ram with one from a WORKING system to test.. if it still does the same thing... switch ur video card with a working one... if this still doesnt fix the problem.. if u have a spare working processor.. put that one in for a try.. if everything fails.. i guess there is something wrong with the motherboard..
hmm.. to configure the PnP option.. check ur BIOS setting to make sure PnP is enabled.
I have a very similar problem. I have an old 200 mhz computer that runs Windows 98. I just got a new windows ME computer and was switching some of the things out. I was trying to switch the RAM out of the old one so I could have a little more in my new one. After I did this the monitor stopped working and was flashing the lights that I think mean no signal. I then plugged my other monitor in, but it didn't work either. I put the old Ram back in but neither monitor works. The second monitor i put in was on the ground at the time. It this bad, could I have shorted out my video card. Also the monitor that did work had been left in my car with the window down and got some rain on it, it still worked but it wonder if it is shorting out my video card. Let me know any suggestions that you have and I will greatly appreciate it. I have other monitors and computers that I could try hooking up, but I don't want to break anymore monitors or video cards until I know what I am doing.

do u know the BUS speed of the OLD ram from ur old computer? i mean.. if ur old computer was a P2.. and the ram was 100 mhz .. AND ur new pc was a P3 or a P4.. of course the ram is not gonna work... for p3.. u need 133 mhz ram... a 133 mhz ram can function in p2.. but not the other way around..
if ur new computer is a p4.. then u'd better find out what bus clock ur motherboard supports..
Is there any other reason why the monitor might not be working? Cause I'm having the same problem, but the computer and the monitor have always worked just fine together for about 6 months, and suddenly when I move it to a different location I get 'No Signal.' Can anyone help me with this??
Hi! I am having a similar problem... My monitor says, "No Signal" However when it turns on it beeps twice and then beeps 6 times. I looked for a 6 beep code and it said it may be the motherboard or something with the keyboard... It was working fine until earlier today and then it just suddenly went out and said no signal... anyone have any idea what i should do?
