Monitor states no signal, I tried the monitor on another machine and it works great. Computer will not reboot

Need to eliminate possible causes. Easiest way is to try your monitor on another computer, if it works then that is ruled out. Try your computer with another monitor. Try another cable between computer and monitor (both yours and borrowed one). The problem can be the monitor socket and wiring, the computer socket, wiring or program and finally the connecting cable.

Make sure you are connecting the monitor signal lead to the correct signal output on the rear of the machine. Some desktops have extra video out connectors when they have a graphics card fitted. If yours has a graphics card the display connector will be away from the back USB ,audio and keyboard ports and near to some silver pop out panels near the bottom of the tower.

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

If the computer hangs for a while and reoots and then works the monitor, it tells me that the signal to the monitor went dead until rebooting. It is as if you unplugged the monitor from the vga or dvi card, or it was getting an incorrect signal from the vga or dvi card. It may not be the monitor, so much as it is the computer doing this to the good monitor.
One can test to see if the monitor is bad by using it on another computer tower or desktop to see if it does it there. Good luck on this diagnosis.

I was just dealing with this last night. My pc would come on, but I kept getting a "No Signal" message on my monitor. I first plugged the machine into a known working monitor. It worked fine so that eliminated the video card issue. Then I plugged the monitor into a different computer...it too worked. So I knew that the monitor was good. I then switched the cord from the faulty monitor and still didn't get a signal. I proceeded investigating the issue. I found that if you boot the machine in safe mode, it actually caught a signal. So...I figured it must be something to do with the resolution. My solution: Boot the machine in safe mode, change the resolution in the control panel and reboot the machine. If it doesnt catch the signal booting in safe mode, I suspect it is a faulty video card. You are likely to find what you are looking for online at zipzoomfly.com or newegg.com

vga cable or check to see if monitor is pluged in check outlet may be bad '

Connect a different monitor to your computer, to see if the video-card in your computer is working.

Connect your monitor to a different computer (desktop/notebook) to see if the monitor is working.

Connect the monitor to another computer (laptop?) to see if the monitor works at all.

Try connecting another monitor to your computer, to verify that your computer is emitting the correct video signals.

your system has a monitor problem try reinstalling the monitor driver through the monitor website

You'll need to check the cable connections and the computer that it is attached to. The monitor may be going into standby mode because the computer went into Suspended/Hibernate mode. Try restarting the computer. If you're unable to do this, try a hard power off and then try to turn it back on.
