As I write to some other question: Run your system in 'Safe Mode'. Go to Display settings and set lowest possible resolution. Then restart computer and run windows again in normal mode. Should have normal screen. If this will not work - then under safe mode uninstall graphic card. Then run windows with standard ones and in LOWEST possible resolution install drivers again. I have had it many times and it made swear first time.

your monitor has no problem, its your cpu. Try to hook your monitor to your laptop,and change the display setting to your LCD monitor.
If LCD has displaying no signal mean signal coming form the Video card of your CPU
try to visualize if you hearing some beeps into from CPU, some motherboard has beep codes
if there's an error or failure to your CPU, 1 beep means its good system test.
if you don't hear any beeps, try to check first your Video Card
if you have Spare try to replace it, try to reset all the connectors even Memory card to its slot.
reset means pull the connectors and place it back again,
also check the power supply of cpu if still functioning good.but you can test it by multi volt meter.
if nothing happens check your motherboard most common failure is bloating capacitor, and overheating chipset.
thanks....................hope this helps...................
Please check the VGA cable if its properly connected and make sure two screws are fixed to both end connecting the monitor and the video card.
No signal comes out when there is no signal from the video card to the monitor. That is why you need to check if the VGA cable is fix to both end.
If that did not fix it, you will need to open the casing of your computer. Disconnect the video card from the motherboard. Gently clean by wiping a clean clothe over the contact surface of the video card. Then, reseat the video card properly to the slot in the motherboard. Return the casing cover and connect the VGA cable again.
Just remember doing the above procedure is only when the computer is turn off.
Turn on your PC and see if that fix it.
You will need to replace the video card if by booting the PC you will hear a series of beep codes. If no beeps then you are lucky VGA cable is the faulty one.
You are not getting a video signal to the monitor. The fact that it is green initially shows it's working. When it turns orange, that's an indicator that it is getting no signal from the computer. So the next thing to check is if your computer is actually booting up or if your video card is going bad. Do you normally hear a beep when the computer starts? Do you hear it now? If the answer is yes and no, then your computer is not starting up. To troubleshoot, I would suggest opening the case and disconnecting everything but the video, CPU, and memory. See if it starts. (you should get a message about no boot device if this happens) If still no video, you have a hardware problem most probably related to the video card.
If the monitor comes on and displays a message like "no input signal" or something similar, it's working properly but there is nothing coming from the computer. People often think that the computer is working and the monitor is at fault, when in fact the computer isn't starting up.
When you turn on the computer, do you hear the normal sounds of the power supply fan running and the hard drive spinning? Most computers will give a beep when they turn on and the motherboard finishes some startup checks. Do you hear that? Do you ever hear the normal startup sounds that mean Windows is actually running?
If you are convinced the computer is starting and booting into Windows, I would suggest you borrow a known good monitor to use as a test. If it works, that obviously means yours is bad. In most cases there's nothing you can do to repair a monitor yourself beyond checking for loose connections, bent pins in the signal cable plug, or a damaged cable.
If a known good monitor still has no image, the computer is at fault. Either the video card or integrated video isn't working, or the computer isn't actually starting up. In any case, that's where you would need to start looking for the cause.
Hope this helps you along the way to solving the problem. Thanks fo using Fixya!
It is telling you that there is no video signal coming from the video card. Check to see if the cable from the computer to the monitor is tightly plugged in. If it is and you still get no signal, I'm thinking your video card has gone bad.
when you open your pc now,do you still hear a click sounds like you hear before ,when your computer has no problem yet? now there is no sounds .do the ff..
1.try to press the numlock key and observe it ,if the indicator LED lite on and off,the problem of your computer is your video card,
2.if you can't hear anything, when you open your unit and the indicator of your monitor goes the color orange,pls..check your memory .clean the memory and the memory slots using the contact cleaner .before you replace a new memory.
3. and try to use a another monitor,maybe your monitor has the problem.
