Hi, I have a problem with my HP Pavillion m7000 desktop with a packard bell screen. Ive had a few times where my screen have went on standby mode, the blue light have went orange and screen goes black. I assume thats normal when u arent at ur pc for a while. But when i touch my mouse or my keyboard the screen stays black, then i tryed to turn off the screen and turn it back on, and the screen just stayed black and a little blue box appeared saying ''Message: No Signal''.. then i tryed to reboot the computer, that didnt work either, i unplugged all cords and wires and plugged them back in, blowing away all dust etc so i was sure that wouldnt be the problem, i even got a new cord to the screen cus i figured that it might have a loose connection or something, that didnt work either.. I have had the problem a few times where it helped to unplug and plug it back in, but now when that doesnt work anymore, i have no clue what to do about it. When i restart the computer it sounds exatcly like normal, everything seem to be running, i can hear the windows sounds at start up, i can hear skype and messenger logging in, but the screen stay on standby mode. What can i do to fix this problem? Thank you in advance.
