Make sure the light on the monitor is on, if it is, turn it off, and turn off computer, and unplug or turn off power switch on your surge protector. On the back of the monitor, there is a cable that comes from the computer, take it off and put it back on. That same cable, take it off from the computer, and put it back on. Now turn them all 3 on (don't forget the surge protector hehe). If that doesn't work, borrow a monitor, and try it. If that works, your monitor is probably bad. Oh, there may be a reset switch on the back, push it in, then turn them on. If BOTH monitors do not work, try a different cable, if not, something inside the PC is bad or loose. You can unplug computer, and take off the case. If you are somewhat mechanically inclined, take off the cable for the monitor, and if there is a card that is screwed down tight, but is removable, take it out, and put it carefully, and evenly back in. Put cable back on and try it again. If that doesn't work, it is time for a new video card, or mother board. If you have a buddy with an old compatible video card lying around, see if you can borrow it. (It may be bad also, from lying around, especially without a static bag.) If that still does not work, probably let someone replace the motherboard, or just get a new (used) PC, can you say Craigslist? Just be careful, a LOT of them are way overpriced, but there are good deals there too.

My monitor screen is black. The green light is on but black screen


The green light usually indicates that the monitor is getting a signal.
The lack of a picture is an indication that the monitor itself is having a problem. I would test the signal with another monitor if you can get one.
I suspect that the monitor backlight has gone bad (if so, you can see the screen very faintly if you shine a light on it).
Or, the screen circuitry has gone bad.

Getting a black screen and no device found. what


First unplug everything from your AC/outlets.Then systematically check every plug going to and from your screen by pulling them out one by one and reattaching them. POWER cord / VGA cord .The VGA cord looks like a D and has 15 pins it goes in easy no force is necessary, thumb tight the screws on each side.Now power cord make sure it's tight, in the socket.Then plug your AC plugs back into the wall. If that doesn't solve your problem either your screen has gone bad or your video card. Good luck!

Is this a desktop pc? try connecting a different monitor while the computer is on. Your current monitor might have gone bad.

My sony vaio makes a beeping sound one long and to short beeps and it wont turn on


One long beep and two short beeps usually means a video problem. If you have an add-on video card, try replacing it with a new one. If you are using an on-board video, go into the bios and turn it off. then shut down & install an add-on card.
