Probably a bad monitor. Could possibly be a loose cable but I doubt it. Try using a different monitor to see if it turns pink a well. If it works then its the monitor. It (the monitor) might just need degaussed (demagnetized). There's a button on it somewhere that you push and it makes a sound like it's lost power for a second then comes back on. You can try it 3-4 times waiting about 5 minutes in between. Try that first then try a different monitor.
There might be a tool on your computer about that, you can check the utilities programs on your computer by searching in the Program groups of your Start menu and disable it. Your manual may give you some idea how to disable it. If you right click on that pop up window you might see an option to stop it from popping up. If those are not working, press CTL+ALT+DEL and select the task manager, then kill the process with a similar name. But you don't want to kill too much otherwise other applications may be affected too. Hope that helps.
Do this to check if your monitor is in working state or not...!
Step 1:- Turn on your computer.
Step 2:- Unplug the Video Cable of your monitor which is connected with the computer.
( Video cable:- Cable going from the back of your monitor to the back of your tower. It has a plug with two screws on the plug ends, which you can unscrew to unplug it. Thats how it looks like. Some times it is in grey in color some times in blue.)
Step 3:- Now check on your monitor. If the display says " No Input Signal " :- your monitor is fine. Some thing wrong with the computer graphics.
If there is not display and the monitor light is blinking or solid the monitor has gone bad.
( Note :- Remember when you unplug the video cable do not unplug the power cable of the monitor. )
The only suggestion useful to you would be to unplug all the wire from the back of the unit. Wait 3 minutes or so and then plug them back in.
If your audio is hooked into your monitor then no picture and sound might be just be your montior (if the lights on the computer stay on). Hit the CD eject button on your computer after giving your computer a chance to boot up. If it has power then for sure it has to be your monitor.
Otherwise the problem will be in the powersupply or the motherboard. Hope this helps. Best Regards, -md
The monitor uses a widely-available standard VGA cable with what are called D-sub connectors at both ends. You should be able to find one at a large office supply place like Office Depot or a retailer like Best Buy. (If you're outside of the US, you probably have similar stores in your area.) You can also purchase the cable online. Here is a suitable cable from Newegg.com, a company I buy from frequently. I've just used this as an example. There are many other sources.
if the monitor goes into standbye when you plug it into the computer , it generally means there is NO signal coming from your video adaptor.
Plug the old monitor in , if it works, ide suspect the new monitor(s) are not working correctly.
if it doesnt work , you need to restart the computer in safe mode by repettitively tapping the f8 button as the computer starts, before it says "starting windows".
If you have a signal on your monitor in safe mode, then most likely you have a bad or corrupted video driver and it will need to be updated.
if you have no video in safe mode , you will need to remove the cover and physiclly check that all add-in card power cables and memory chips are squarly seatied in there slots. MAKE SURE YOU UNPLUG THE COMPUTER AND DISCHARGE ANY STAIC BUILDUP IN YOURSELF BY GROUNDING (TOUCHING) SOMETHING METAL BEFORE YOU TOUCH ANYTHING INSIDE THE COMPUTER.
AFTER YOU CHECK THESE THINGS AND TRECONNECT THE POWER AND TRY TO START......POST AGAIN HERE
