Re: no video

It's not necessarily the video that's the problem. Anything that would keep the computer from beginning the POST process (beginning of the process of booting your computer) could also result in no video. When you start the computer up, does it beep at all? If so, how many beeps, and are they long or short. The order and lengths of the beeps are the most basic type of error codes. Also, do you hear the hard drive spinning up? And does the CD/DVD ROM drive start up normally? It could be a power supply, your processor, memory, the motherboard or just the video card. It could also be just about anything in the computer if it developed a short, as a single short can cause the power supply to shut itself down so as to protect the computer from being further damaged. I would suggest disconnecting power to the drives, and trying again. If it boots to video, you know one of the drives is the culprit. If they aren't the problem, try removing the memory. It won't boot that way, but if the memory is the problem it will at least reach your POST and give you the option of entering BIOS. If you get that far, the memory is at fault. Then, try the same with any expansion cards onboard. If none of that causes it, then you either have a bad processor, bad onboard video, something else wrong with the motherboard, or bad power supply. Unfortunately, none of that can really be tested without having parts to swap out.

I have a e machines desktop that will not boot up. I turn it on and the monitor says no signal. I think it might be stuck in hibernation mode. The fans on the tower start but thats about it. If some one...

No Signal means you Display or Monitor is not getting signal from Video Card.
In this case:
1. Check if all the cable are properly plugged in. Check on both monitor and computer back. 2. Check if cable is not broken. 3. Try unplugging cables and plug them back. 4. Try some other monitor or cable. 5. If cables are fine than problem could be with your video card.
As you are getting No Signal that mean your monitor is working fine. Problem is either with cable or video card.

I have an HP the monitor doent turn on but all the light are on how can i fix it.

1. unplug the monitor from the computer and check if you can see the monitor selftest (you will see diff color bars moving around) if you see the monitor self test then your monitor is working fine

2. check the cables. use a diff cable to connect your monitor to the computer. use a known good cable.

3. plug in your monitor to diff computer if it worked then you have to reseat your video card
(NOTE : before removing any internal parts from your computer. your pc must be off and the power cable is removed, after removing the power cable press the power button for about 5 secs to remove any electro static discharge)

4. after reseating the video card and still doesnt work remove the video card from the computer. use the onboard video card if you have one.

if it does work then the video card needs to be replaced.

you can also try to reset the memory by removing them and reinstalling them inside the computer

hope this help

Blank screen but sounds like computer is on

If the screen is blank, since you press the power button then you can try to use another monitor to see the functionality.


You can disconnect the VGA cable of the monitor but keep it powered on, if you get a display on the screen like "Check input signal or Check video cable" then monitor is fine.

If you are using a Dedicated video card in your pc then disconnect it and try using the on board graphics port and see if its working.

Monitor screen changes from regular color to a green tinted screen?

Connect a different monitor to your computer, if it still displays the same fault the the problem is the video card and you need a replacement.

E-machine was working fine last night got up and it turns on but the monitor says check cable or power but all is ok.Computer wont display anything, can anyone help?

Do a reset: Turn the computer and monitor off. Unplug the monitor video cable from the computer and unplug the monitor power cord from the wall outlet. Let it sit for 5 or 10 minutes. Plug everything back in, turn on the monitor, then start the computer. Sometimes that will work.
If you still have the same problem, try to borrow a known to be good monitor from somebody. If it works, then you know your monitor is bad.
It's also possible that your video circuitry is bad. If the monitor plugs straight into the motherboard (onboard video), then you'll need to purchase a video card and install it. Disable the onboard video first.

Computer powers up, but monitor shows a self test

Your video output is bad. Either the video card, or the onboard video built into the computer. You need to swap out the card or add a card to bypass the built in video port on your computer.

Thanks and please take a moment to rate as fixya.

When I try to turn on my computer the monitor reads: VGA input: no input signal

The monitor is telling you that it does not see the computer. First, remove the monitor cable from the back of the computer, check for bent pins on the connector and replug in the connector.
If that doesn't work, try swapping to a different monitor to see if it sees the system. If this works, you have a bad monitor or monitor cable.
If that doesn't work, open up the computer remove the video card, clean any dust from around the card and socket and replug the video card.
If these ideas don't work,get back to me and we'll go from there.
Have a good day!

Monitor problems

It is possibly your video card that is having the fits. Try replacing your video card or have your CPU checked... It is not a problem with the monitor, rather a problem with the computer...
