Your screen has gone to standby to save power, just wiggle the mouse or click. and it should come back. You go into your computer options and change the preferences so it will not do this as much or not art all

Unfortunately, a computer is not yet as consistently reliable as a refrigerator or a toaster. A computer can and will misbehave on occasion. I've heard all the laments. My computer just crashed. My screen is frozen. My system is running too slow. No matter what you call it, there is never a good time for a computer to act improperly. Unfortunately, this is a normal part of computing in today's world. You may or may not know what has caused the problem. But in the end, it is the way that you handle the problem that will make all the difference.\n\nLook for the obvious\nFirst be patient. If your computer fails to respond to your keystrokes, it may have a problem. However, the computer could also be busy performing some other function, which you may not be aware of. For instance, your computer may seem to stop when automatically saving a file or when printing something in the background. So give it a minute or two. If it still doesn't respond, look for an obvious problem first. It may sound simplistic, but sometimes the problem is easily found. If your screen is blank, check the power cable. Make sure that the power to the house has not gone off. Also, many newer computers have a suspend feature that blanks out the screen in order to save electricity. Press a few keys to see if the computer will come back to life on its own.\n\nIf your screen is still on, but your mouse clicks and keystrokes don't elicit any response, try a couple of simple checks first. Make sure that everything is still connected. Perhaps your dog just ran out from under your desk and loosened the keyboard or mouse cable. In many programs, the Escape key, which is marked Esc, will take you back one step. So always try hitting the Escape key a few times before you concede that the computer is truly locked up. If you still get no response and the connections check out okay, it's time to go on to the next step.\n\nThe magic key combination\nThe next step is the magic key combination. Find the keys marked Ctrl, Alt and Del. Press these three keys all at once. This key combination is a remnant of the DOS days of computing. In DOS, pressing these three keys caused the computer to restart or "warm" boot. The Windows operating system uses these three keys in a similar, but slightly different way. If you are using Windows 95, Windows 98, or Windows Me, when you hit the magic key combination you will be presented with a Close Programs box that shows a list of the programs that are currently running. If Windows has found the offending program, it will list the words "not responding" next to the program's name. You can then highlight the name of the errant program, press End Task and return to your computing. (You will lose any data in that program that you have not yet saved.) You also have the option of pressing Ctrl+Alt+Del again to restart your computer. This should be used only after you have tried the other options unsuccessfully.\n\nWindows XP handles the Ctrl+Alt_Del key combination slightly different. Pressing these keys in Windows XP will bring up a "Windows Task Manager" screen. (In the Professional version of XP, you need to choose "Task Manager".) Click on the Applications tab to see the list of currently running programs as described in the last paragraph. Most average users will not have to be concerned with the information on the other tabs on this screen. Luckily, Windows XP doesn't freeze as much as previous versions of Windows.\n\nOccasionally, even the Close Program Box and/or Windows Task Manager Box freezes or is inoperable. If this happens, your last resort is to restart the computer. If your system has a restart button, you can press it to restart the computer. If you don't have a reset button, turn off the computer. Wait several minutes, and then turn it on again. It is important to wait a few minutes to let the hard drive and other components come to a complete stop before res

If you are getting something on your screen and then it goes blank right as it is booting into windows.  It is probably because your screen resolution or refresh is to high for the monitor.  Follow Microsoft's directions to boot into VGA mode.  If you aren't getting anything on the monitor Check your cables or the monitor on another machine.\n\nhttp://support.microsoft.com/default.aspx?scid=kb;en-us;315222

This is a permanent damage that has happened to you LCD screen. \n\nThe problem might be dead or lit pixels:\nOccasionally the individual transistors responsible for carrying current to a pixel either short out or remain open resulting in what is called a dead pixel. \n\nA "lit" pixel is one that appears as one of several randomly placed white, red, blue or green pixel elements on a dark background, or you may have a "missing" pixel which shows up as a black dot on a light colored background.\n\nThis can only be replaced by the manufacturer as usually this kind of problem is not repairable in India.\n\nIf your laptop is under waranty period your lucky!

Four things tend to happen to an LCD screen, 1 if the screen goes dark, it could be that the little flourecent tube in your LCD went bad.  2 it could also mean that your LCD inverter went bad.  3 your video harness could of come undone, from either the board or the screen, and last but not least, your video chip could have burned out.  You can rule out most of these symptoms by pluging a monitor up to your laptop to see if it gets a picture.  If your external monitor does get a picture, you know that your video chip is good.  I am assuming that you are taling about a lap top.

Do a system restore. Go to Start, Programs, Accessories, System Tools, System Restore and roll back to a date before your problems started.

Does your monitor do or show anything at all? Or is it completely dead. Check the cords and make sure they didnt fall off. When you turn the computer on do you get a boot up screen and then it goes dead? If so the monitor is ok. The monitor driver my be corrupt or deleted itself, or you might have a bad video card. Try this turn the computer and the monitor on and unplug the monitor cord from the back of the computer if the monitor is ok you should get a message on the screen telling you that it is disconnected from the computer, if you get this message then the cord or the video card or driver is bad. If you have a friend with a computer ask them if you can borrow their monitor. Disconnect your monitor and reconnect it using their cord if it still wont work your cord is fine if it works you then need a new cord. If it still wont work connect their monitor and see if it works if it does then you need a new monitor if it does the same thing that yours is doing, then it is something else and not the monitor or the cord. If their monitor doesnt work either then it could be the the video card or the driver. To see if it is the driver or the video card since you cant check it in the device manager because your monitor isnt working do this. Notice where the cord plugs into the back of the computer,open the computer up hopefully you have a plug in video card (plugs in slots on the board and can be removed) the other kind is a onboard video card which is built onto the board. If you have a removeable card be carefull and pull it out of the computer. Start the computer up and let it run for a couple of minutes then turn the computer off this will clear a corrupt driver from the system bios. Turn the computer back on if the card is ok it and the driver is bad it will ask ask you if you want to reinstall the driver click yes it will the ask you from where click MS web site also click on the C drive make sure that you have it so it searches all the C drive. It will then do a search and if it finds the driver it will ask you if you want to install it, click yes, after you are done, restart the computer if the monitor still doesnt work more then likely the video card is shot.You can find a decent one for around 60-70 dollars at Best Buy. If you have an onboard card then you have no choice but to try a new card. There should be a slot on the board for it just make sure when you plug the cord back in to plug it into the new card and not the onboard connection. As for copying the files dumbbutt4321 hit it on the head go to radio shack and by cross over cables they plug into the usb connectors!!\nP.S. once again I have read answers from people that DO NOT KNOW WHAT THEY ARE TALKING ABOUT. You can NOT switch a hardrive from 1 computer to another without formatting it.. The reason being is that EVERY CPU has a unique identifier on it that installs it self into the BIOS and on to the hardrive. It matches the CPU and hardrive together. Because of this a hardrive will not work if you take it out of one computer and put it into another one without formatting the drive. You have to erase that unique identifier off the drive so that when you switch them the CPU will do its thing and put the id on the new drive so it will match up again! I wish that all you BACK YARD so called computer geeks would leave this stuff up to those of us that actually spent months and alot of money going to school to learn computers and and take tests to get certified. All you manage to do is f+ck up the peoples computer more then it is already!!!!!!!                                                                            GOOD LUCK!!!!\n                             ZEUS

This is extremely odd as in all my years of servicing computers as a technician, I have never heard of a computer screen going black because of a system restore. Lets see, go through a basic check up first.\n\n1. Turn on monitor, attach the wire to video card.\n2. Make sure the contrast and brightness are set properly.\n3. Move your mouse and press ENTER and ESC on your keyboard exit any possible hibernating states.\n\nNow for troubleshooting...\n1. What caused your computer to need to get system restored in the first place? If it is a virus, it might be the cause of this problem and try turning on the system with your system boot disk or windows disk (however this is usually very rare).\n2. Ask yourself, is the system on and running and do you hear the normal beeps and sounds that the pc normally makes when it is booting? (If the answer is yes, then this problem is usually not a software problem as things are running smoothly, it's just that nothing is showing on your monitor. Try getting ahold of another monitor and see if that works. \n3. What color is the monitor's power light? (Usually it is green or orangish). If it is orangish, that means your computer is not recieving the signal from your computer system.\n4. Wait for a few minutes and press ENTER / ESC every thirty seconds or so. If nothing happens, after about 2 minutes or so (about the time it takes the pc so turn on, press ATL F4 and Enter a few times. If the PC turns of, that means it has successfully booted and you definitely have a hardware problem.)\n\nIf none of these solutions worked, feel free to email me at bqm1234@yahoo.com as I am quite interested at what is causing this problem and we can sort it out from there.

1. It could be in Hybernate: try to turn off all power and restart the whole thing from the no-power stage.\n\n2. graphic-card / video setting: \n2.1 there's nothing much you can do if you cant see it but i suggest to turn it all off from the no-power stage and press <del> to go to your BIOS setting. Check if you can mannually overide the settings to a lower mode. If so, try restarting again.\n2.2 from the background, the laptop is starting up with windows but u cant see anything coz the video just might have been toggled with. try pressing <F8> by the time you boot it up, chances are u might be lucky enough to go on safe mode and u can level your video setting to a lower degree.\n\n3. if 1 and 2 doesn't work - i damn hope you have backed up you files coz you have to bring it to a DELL shop\n\nHope I helped you out- coz i had that prob once and # 2 did the trick for me

I'm not saying your problem is what mine was, but last Friday my Dell laptop started doing the same thing.  It would go to the black Windows XP screen and then it would just go black.  And stay black.  I found out the next day, after having the Geek Squad people at Best Buy look at it that it was my motherboard.  I had let the battery die and when I plugged it in, sparks flew up from the surge protector and they said that's probably what did it.  Had to buy a new computer.\n\nIf you have any friends who are good with computers, ask them.  \n\nBut if it is something that can't be fixed, those people were able to transfer all my files (not programs just files) from my old computer to my new one.\n\nGood luck - I know exactly how horrifying that is!!!!

Make sure system restore is enabled. Control panel/System/System Restore. Make sure turn off system restore is unchecked.

Next time it goes blank, try pressing the menu button, if the menu comes up, suspect the video card.  If the menu doesn't display, replace your monitor.  Of course, check the cable connections first.

re-install, restart, check all display settings..
