Ok, so whenever I plug in a monitor to my video card, I get a 'no signal' error. I have tested the video card in other machines and it works fine, and the monitor is in perfect working condition as well. Not sure if there is anything left to try or if I should just consider the mobo dead. Suggestions?

Re: 'No Signal' Error on Monitor
Sounds like you have eliminated the graphics card and monitor. So it must be something else. Try switching the jumper on the MOBO to reset the BIOS. If it still doesn't work it could be many things. Try different memory, power supply etc. You might get lucky.

Re: 'No Signal' Error on Monitor
Does the Mb have an onboard video, is windows running ( does the caps lock work) Is this monitor compatible with SVGA ( old monitors are not) Some older monitors cannot handle the higher sync signals windows can be set to. You really need to have another monitor to test with before rejecting mb.

To help you troubleshoot the monitor 'No Signal' issue, please find the steps given below:
- Turn off your computer.
- Unplug the cable running from your monitor to your PC and plug it back in, making sure the connection is firm. The most common cause of this error is a loose cable.
- Re-attach the cable running from your monitor to your PC. If the monitor is still not displaying a signal after firmly reattaching the cable, the problem could lie with the cable, especially if the cable has visible damage.
- Replace your monitor with another monitor if possible. If the 'No Signal' error still appears, the problem does not rest with the cables or the monitor, but with your PC.
- Open your PC case and locate your video card. Remove the card and then replace it firmly in its slot or, if possible, insert the video card into another slot on your motherboard. A video card that is not making a firm connection will not display images to the monitor. Close your PC case and test the monitor again.
- Replace your video card completely. Your video card may suffer from internal damage that is not allowing it to output a signal.
If issue persists, it is recommended to contact your monitor manufacturer for further assistance.
That more than likely means the video (graphics) card inside the
computer is bad. The monitor seems to be ok if it is displaying No
Input Signal. Isolate the problem by connecting another monitor to the
computer. Borrow a monitor from a neighbor, friend, relative or
co-worker and connect it t the computer. If the Borrowed Monitor
displays the No Input Signal then your video card inside the computer is
bad. If the Borrowed Monitor works and displays your desktop icons,
then your original monitor is bad and the video card is ok.
Check the cable at the back of the monitor and at the back of the computer. If the cables are in tight and you still get the no signal error message you either have a bad monitor or a bad video card in the computer.
Try plugging another monitor into the computer (borrow one from a friend, neighbor or family member if you don't have one). If the monitor does the same thing and shows a no signal message like your original monitor, then the Video Card in the computer is bad. If the monitors works, then your original monitor is bad.
please test the power source that the computer is plugged into and confirm it is working with a lamp or something.
If power source is confirmed working and the computer is plugged in and it is turned on and there is still no signal to the monitor and the ethernet lights are not on when the cable is plugged into it. Also check that all cables from the monitor to the computer are connected properly and secure. if the above has been done and still no signal then there are some Possible Causes
1. Mother Board failure (video card on motherboard is defective)
2. Monitor Failure (computer is sending video signal but monitor can not process it)
3. Video Card failure (if the video card is not designed into the motherboard)
Troubleshooting and repair
See if you can get access to another monitor to test the computer with to see if it sends he video signal ok to that monitor. If you can not get access to one then the only option is to get a video card and either you can install it yourself, or have it installed at a repair station.
If you purchase the card and install it yourself most stores will let you return the cards if they do not work or they are not usable. If you do go that route just make sure to ask about return policies prior to trying it.
I would really consider replacing the video card first you can get them from 30.00 and up and there is ony a few screw to remove to install them. Most of the video card manufactures also have tech support for helping people with the installations of the cards.
I would not worry about the lights on the modem or network card until the monitor issue is resolved so you can then see if it is indeed making a connection to the internet.
disconnect the plug, assuming it's a dvi plug if it;s a vga standard plug the idea is the same unplug it with the computer running and see if plugging it back in dose anything. no? ok shut off the monitor and the computer completely, unplug the monitor for 15 seconds, plug the monitor in first, now power up the computer and see if the wake signal is sent to the monitor, if it is then the monitor will power up as normal and All's ok, if not then theirs a possibility that the video signal is not coming from the video card, some cards are external agp cards, like higher end cards, they require a significant amount of power to run properly, and will fail if not powered up, test this by unplugging things not necessary to boot the pc. and see if it starts up, chances are you have a inboard video card and a external video card, if so plug the cord into the internal card first and enter the bios settings, from here check that the inboard video settings are disabled, this way you can plug back into the external if it is indeed external.
sounds like it might be a graphics card. if u have an old graphics or vidio card, open the case and remove your card then install the old one. if it works now youll know your card is bad. If u have an old video card and an open pci slot install it and move the monitor cable to the old video card plugin. if it works now same thing your graphics card is bad. to know which card to remove just remember which one the monitor is plugged into.
Check to make sure you have correct ram installed in motherboard as the video card may share that ram. Check CPU that it's installed correctly and video should work. If not then the motherboard is bad.
1. The cable linking your CPU to your monitor might not be properly plugged or has been damaged. You should hence ensure that the connection between the two devices has been properly done and that the cable’s state is fine.
2. You might be facing a problem with your monitor if the CPU makes a single beep error sound when you switch on the system. You can check whether the problem comes from your monitor by testing it on another CPU. If you still have “No Signal” error displayed including the error beep, I would strongly suggest you to try to get your monitor fixed by a competent technician or to get a new monitor.
3. If you receive several error beeps when starting the computer, this might be linked to a graphic card dysfunction. You can refer to the motherboard notice or check that the connection has been properly set
Hope this will give you ease of mind and or hints. The No Signal error screen message is normal it depends how much delay it responds to (design or default time delay) the video card down to CPU and control units. The blank screen can be resolved by turning off the screen saver(s) you have and even to BIOS mainboard setting; disable the "turn off monitor after how many seconds" or related menu, etc.. Hope you can manage to enter BIOS maiboard setup.
1.there might be a problem with your signal cable. if one of the pin in the signal cable is open. it might also happens 2.adjust signal cable. 3.Check VGA video card is working properly. unplug the VGA card and Re-plug to its slot. if your mother borad has inbuilt video card. this process cannot be performed 4.Even problem with operating system might also happen.. problem with Video Ram memory 5.if you want to check whether your monitor is ok. just get Cpu Box alone frm friends for a while for a testing. 6. if your monitor have problem then contact service centre.
