Re: no signal display on monitor.
Hello, 1. Check all the connections to make sure they are connected securely and properly. 2. Open your tower case and make sure you video card is seated properly by removing it and then placing it back in the slot. While you have the case open it would be a good idea to clean the inside of it out with some compressed air (remember to always unplug your system from the power source when working inside it unless you are a qualified technician). 3. If problem continues, try using another monitor to check if your monitor has gone bad. If it displays ok on a different monitor then your monitor is bad, if it still does not display you may need to replace your video card.

This should be posted in monitors. Does the screen display anthing during boot up of the computer? Does it appear that the computer is booting? If the computer seems ok, then plug the monitor into another computer. If it works there, then it is something with the computer, and we will need a bit more information to work with.
This means that your monitor is not receiving a signal from your graphics card.
Here are the things that you can try:
-Disconnect and reconnect your monitor from your computer.
-Try using a different cable to connect your monitor to your computer.
-Try connecting your monitor to another computer, if it works there it means that there's a problem with your graphics card and it may require a replacement. If your monitor is still saying no signal even if it has been connected to another computer that works fine then the problem is with the monitor.
You are most likely using a resolution that is too high for your monitor.
Reboot the computer pressing F8 after the power on self test of the system and the Windows loading screen. Select the "Enable VGA Mode" option. This will boot to your desktop with a lower resolution that is compatible with your monitor.
If the Monitor is displaying no infomation at all, your display signal from the PC to the monitor has failed. 1: Check the cable between the monitor and PC 2: If you are using onboard graphics then that display port is faulty. 3: If you are using a graphics card then remove it and try the onboard graphics. 4: Your monitor maybe faulty aswell so test it on another computer to be safe.
Do the icons look ok when you can see them? It sounds like your resolution may be way too high for the monitor. It loses sync and blanks the screen rather than show a lot of mess.
Boot your windows in safe mode (tap F8 before it gives you the progress bar.. just keep tapping it until you get a boot menu)
Everything should look big, but the monitor shouldn't cut out. Go to your display properties and set it to the lowest setting. (even if you can't move the slider, just click it once) Then OK and restart.
If that works, you should be in normal Windows with a horrible resolution. Go back to display settings and set it ONE STEP higher. Apply and have a look. If it's good, go another step, and repeat.
If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.
Problem with the monitor, monitor cable, or video output. For monitor, if you have more than one input, make sure it's set to the correct one. Try a different cable. Try a different monitor. Check your video card settings--if you see the BIOS bootup screen while it's coming up then the Windows splash screen, then monitor blanks out, it's a Windows display setting. Boot into safe mode, then change settings--
Turn the computer on or Restart the computer
Start tapping the F8 key. The Windows Advanced Boot Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
Ensure that the Safe mode option is selected (the top option)
Press Enter. The computer then begins to start in Safe mode.
When you are finished with troubleshooting, close all programs and restart the computer as you normally would.
Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:
* Off entirely. * Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode. * Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer * On fully, receiving an image, and displaying.
