  1. Its a weird problem. It has been working fine for over a year and little bit more. Suddenly the monitor lost input signal, and went to sleep, while the computer is still running. The monitor hasnt gain signal even if i restarted. It keeps sleeping, because it doesnt have any input signal. Also when i leave it on it suddenly gets signal an has display for a few secs or min, then loses it again. What could be the problem? If it never had happen before. What should i do or any recommendations, Suggestions?

    Update your video card drivers from the manufactures site. If you cannot get to that point, unplug your power and video card cord from the back of your computer, then hold in your power button for a minute. This will suck up the remaining electricity. Then of course plug it all back in. If this works still make sure to update your drivers\windows update.
