My monitor is not responding when I boot my computer. After I unplug the monitor from my computer I can't even get the monitor to say no signal. I am wondering if it is a bad monitor or if I just had a bad graphics card?

One sure way to know if you have a bad monitor is see if a friend will let you borrow his/hers and plug your tower up and if starts up just fine then your monitor is bad, if it still does not come up on the screen then most likely your video card needs to be reseated or it is bad. You can open your case and re seat your video card and see if that has any effect on your situation first. Hope this helps

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.

My dell 470 wont boot up every thing seems to be working but when i turn on i get a blank screen and no signal displayed Edward


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.

My computer will turn on but my monitor does not get a signal and I've tried this on two working monitors and two different power chords. The lights on the keyboards don't even work. Any solution?


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

hi ,
check the pins in the monitor plug as they can be bent , and also check your mointor is set to accept an input from your lead ( serial/hdmi etc )
Some monitors have a built diagnostic which is often colour bars , if your monitor shows this then its almost certainley a lead problem

hope this helps

Monitor and keyboard won't turn on


A couple of things here:

1) The flashing light and signal message indicate that the monitor is functioning but is not receiving a signal from the computer.

2) The memory that you added is liklely to be incompatible with the computer itself and is preventing the system from booting. The computer will perform a selftest when powered on. Normally when there is a memory issue, the unit will beep. In some cases, there will be no action.

Remove the added memory and attempt to boot the system. If it starts up OK, then the memory you have added is the problem.

Update this if you require additional assistance.

Thanks,
Dan

Pc wont read monitor


If you look at the monitor there will be an led light on the front that is always orange or yellow when the computer is off but still connected to the monitor. This led will turn green when the computer boots up, sometimes even showing a "no signal" display before boot. If you see the 'command line'  text during the boot process (video info, BIOS version, POST text, etc) then the monitor is being recognized by the computer. If that text goes away and the led goes back to orange then it is a driver or operating system problem. Pressing whatever key is prompted at the lower left of the display, if you have a display, like F1, F2, F10, Delete or whatever will get you to the setup program and all is good with the display/computer connection and a green light will stay on. If you never get that green led light then either the video card is bad or not seated properly

Monitor says no signal


this could be a multitude of things. Firstly, check the connections from your computer to your monitor, unplug them and plug them back in, make sure the thumb screws that connect your monitor to your computer and nice and tight but dont use a tool to tighten them, hand tight is good enough.
If that doesnt work, then check that your graphics car hasnt been unseated from its slot, TURN OFF THE POWER to your pc, open the case and look at the graphics card inside. Push it straight back against the slot and that might help.Try connecting the monitor to another computer, although I dont think its a monitor problem. or borrow a monitor from another computer and try it. If that doesnt help then you can try a different graphics card, if you dont have one they are readily available from most major electorincs stores, or even most supermarkets with an electronics dept. Now if you do all this and it doesnt fix it then you will need to find a tech to have a look at it, Like I said at the beggining it could be a multitude of sins, a hardware error stopping the computer from booting and that requires a little technical knowledge
