Try removing and then reconnect the monitor cable from your pc then try again to start it. If it doesn't work, Did you do something that might cause this problem to the computer? Did you hear some unusual beeps as you turned on the pc?

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


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.

Please post back in a Comment.

Dell xp620 is not working


No Signa where? No Wireless Signal? Or is the monitor saying No Signal?

If you are saying the Monitor says No Signal, then more than likely the Video Card in the computer is bad. Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor does the same and displays No Signal, then your video card is bad. If the Borrowed monitor displays and works ok, then your original monitor is bad.

Monitor will not boot up is reading no input signal


So either the computer isn't generating a video signal, the cable isn't carrying the signal to the monitor, or else the monitor isn't capable of receiving a video signal.To test this, first try a video cable that you know is good, in case your cable is bad, If it works with the other cable, the problem was your original video cable. If it still doesn't work, put your original cable back, and hook another computer up to the monitor. If the monitor makes the same message, the problem is with the monitor. If the other computer works when connected to this monitor, your problem was that the original computer isn't booting (which could be due to several reasons I will list below), or the video adapter is broken.Possible reasons for the computer not booting: bad power supply, bad power button, bad hard drive, bad memory, bad motherboard component. If you determine that it isn't booting, unplug everything except the keyboard mouse monitor and power cord, to see if that makes a difference. If it boots after that, something you unplugged was causing the problem, plug them each back in one by one, rebooting in between, and when it stops booting properly, the last thing you plugged in is causing the problem.

When i on my desktop it show blue screen and says no signal analog


That means that the monitor is not getting a signal from the computer. There are several possible issues involved. 1) Make sure that the computer tower is on. 2) Check that the video cable is connected to the active port on the desktop. (Computers often have video connections on the motherboard and an added video card. The motherboard connection is disabled when the video card is active. Similarly if there are several ports (VGA, DVI, HDMI, Display port) only one may be active.) 3) Try a new video cable (if possible) and one of the other video ports (again if possible). 4) Try connecting a different monitor to the computer or connecting this monitor to another computer.

Open up the computer and check if the card requires a separate power connection to the power supply. Make sure it is plugged in. Do the fans in the computer spin up?

If a second monitor doesn't work or the monitor works on another computer, then the problem is with the video adapter on the computer, the power supply or the power switch. Please add a comment with more information about the type of desktop and the current video graphics adapter (on the motherboard or separate card). I will provide additional help if possible.

(who has a computer in the company that needed a new monitor (power supply failed) a few months ago and lost the fan on the video card last week. Without the fan, the card overheated and shut down. Thus no signal to the monitor.)

Me e machine desk top has been stored away for 6 months, i have set it up & the monitor won't stay on & it's saying no signal?


When the monitor says no signal, it means that it is not detecting a monitor. You need to check the cabling of your monitor and verify that it is properly plugged in. Normally its a blue VGA connection or a white DVI connection that goes to the back of the computer. Also, some monitor requires a seperate power source and you need to check this as well

My monitor suddenly lost signal and hasn't returned


do you mean the processor fan that is located near on the left top corner on the motherboard? if that stopped working then turn of your pc immediately. probably the cpu overheated. if that fan does not work replace it immediately as it will burn the cpu.

Samsung 940B monitor, 14 months old. Power light on when connected to PC, but no images, not even menu or Digital/Analogue prompt. PC recognizes the monitors presence,any ideas please?


Monitors are passive components in a computer system. These just receive signal from the CPU. You may find another CPU and connect your monitor to it to test if it really doesn't work. If it works, this may just mean that your video adapter has a problem.

You can also check the cable attached to the monitor. It may be damaged due to twisting or other causes. Check also if the port is inserted firmly.
