What's going on if my pc monitor shuts down suddenly and then i have to restart my pc...once it dind't start

Start with the basics, first.\n1. Is the monitor plugged in to a power source?\n2. Is the little green light on indicating the monitor is on?\n3. If it is on, do you have another computer that you could test the monitor with?  You want to make sure before you go replacing your video card that it's not your monitor.\n4. If it's not your monitor, do you have another monitor to can test your computer?\n5. If the 2nd monitor doesn't work with your computer, check to make sure you haven't wiggled you video card lose.  Be sure to turn the power off to your PC, unplug it from the wall and wear an anti-static wrist band before toying with the insides of your computer.\n\n-PCI video cards are notoriuos for coming lose if they aren't held in place with the set screw.  AGP cards not so much but still can come lose.  \n\n-Take a look at the card where is plugs into the motherboard. The card itself has many copper connectors that you shouldn't see when it's properly installed.  If it's in there slightly ascew you may see these copper strips more easily on one side of the video card that the other.  If that's the case... firmly reseat the card.

If Windows XP suddenly starts without warning, or restarts when you try to shut it down, it may be because your operating system is set to automatically restart when certain system errors occur. This feature of the Windows XP operating system can be disabled. Use the information below to disable the Automatically Restart option. \n\nResolve this issue by turning of the Automatically Restart option: \n\n1. Click Start, right-click My Computer and click Properties. \n2. Click the Advanced tab and select Settings in the Startup & Recovery section. \n3. Remove the check mark next to Automatically Restart under System Failure. \n4. Click OK to close the Startup and Recovery window and click OK to close the System Properties window. \n5. Restart the PC.\n\nThe PC will no longer restart automatically when a problem occurs. Instead a blue screen appears with more useful information. You can now search for a resolution using the text from the error.\n\nAfter you perform the above steps, check if the issue persists in "safe mode with Networking", scan for virus, get the BIOS update from the manufacturer.

could be the graphics card, try a different driver, also try a different power cable for the monitor, very unlikely it is the cable but worth a try. If you have a nother graphics card you could try then try that, if problem still persists then it is your monitor, may still be under warranty, you may want to check that.

Another common cause of sudden shut-down is overheating. If your laptop is making a lot of noise when it goes down, this may be the problem (or, if your fan is broken, if it doesn't make any noise...). Sometimes these temperatures can be checked in the BIOS, take a look when you restart immediately after it shut down. There are also some programs available for free on the net that can monitor your system temperature.

Shutting down your PC should ALWAYS be done by using the "shutdown button". Windows will unload certain components from the memory, save it's present settings and flush the virtual memory when doing so. \nAs stated in the former comment, shutting it down by the power switch (aka hardware reset/shutdown in contrast to software reset/shutdown) will result in the loss of ANY non saved information on your pc and mey provoke STRANGE results on boot-up (desktop settings lost, driver missing etc...). It should ONLY me a last step measure when the pc hangs (does not respond).

It looks like your monitor is either going bad or you have a loose connection.

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

Make sure the power cable and video cable are securely connected.  If that doesn't solve the problem, hook your monitor up to a friend's computer.  Same problem?  Then you have a bad display.  Works ok on a different computer?  Probably a bad video card in your computer.\n\nI'd also suggest using different power and video cables if you have access to others.  You might find that you just have a bad cable.\n\nGood luck

that sounds like a problem with your computer screen. the colors change when the monitor is about to stop working

It could be your video card has died.  Or try a new monitor cable.

download the current driver for your video card. if that doesn't work your monitor or video card might need replacement. Also try to degause your monitor if its not a plasma screen.

multiple things could be the problem, you'll have to do some troubleshooting.\n\nFirst I would check that the monitor is plugged in correctly and powered up. There is a plug, ususlly blue, plugged into the back of the tower and leading to the monitor. two manual screws hold it in place. untighten the screws to see 15 pins. make sure all pins are intact and not bent. plug it back in tighten screws, power on pc, give it a second and see if it works. if not... \nNext I would check the monitor on another computer or try another monitor on the first computer. If the monitor is not fried, its likely you have a video problem. \nIf its a video problem, you are going to need to get a video card. ask at your local computer store. buy, or borrow one from a friend for testing. you might want to open your tower first to see what kind you need.\nGet some canned air and a small screw driver. \nBefore you open the case check to see if you have onboard video or a video card. You can do this by seeing if the Video plug(vga 15 pin same as before) is located behind your I/O shield (where the printer port, mouse keyboard and usb ports are) which would mean its onboard. If it is in one of the long horizontal slots, its a card. \n\nunattach the VGA cable and Open the case. Its usally either a screw on the back and then sliding it off or a handle that you can use to pop it off.\nBefore touching anything make sure the power is off, but the computer is still plugged in and put a hand on the metel case to ground any static electricity in your body. esd can damage your mobo. \nplug your nose and close your eyes and blow out that dusty mess with the canned air.  \ninside is a mess of cables that can be scary but bare with me you are looking for a speciffic thing. you should see the power supply with all the multicolored cables running to the cd rom hard drive and other stuff. Then there is likely some IDE cables (flat ribbon cables connecting the motherboard to the hard drive and cdrom.) on the mother board there will be some slots (usually white) that correspond to the slots on the back of the tower. in these may be the video card, if so you have a PCI video card. If the card is plugged into a similar slot that is shorter, set back more, closer to the inside of the motherboard and probably brown or blue (also corresponds to a slot in the case usually the highest slot), it is AGP. If you have onboard video just see if you have an AGP port so you can get an agp video card. (note there is a new technology called PCI express but unlees you bought your computer in the last 6 months don't worry. ill assume you haven't otherwise you'd just use your warrenty)  \nso get yourself the correct video card (agp or pci agp is better).\nPull the old one out (unless you have onboard video) \nThe long piece of chrome metel attached to the video card is bent at the edge and there is a screw in the top. (or there is a clip over all your expansion cards) unscrew or take this loose. agp cards sometimes have a plastic clip on the back to keep them from popping out, unclip this.\npull strait up on the card, some force may be required but don't break it. handle all circuit cards by thier edges only as much as possible to avoid esd. \nUnpackage the new (or Known good) video card and insert it the same way you pulled the old one out. make sure that it is seated well. put the screw or clip back in place and close up the case. \nattach the cable to a known good monitor and power up.\n\nif this doesn't change anything, its likely that your motherboard is freid. if this is that case you will need to have a professional work on it for you or just buy a new pc.\ngood luck.

My best guess is a dead hard drive.  Does the computer make it past the Post (power on self test) screen.  Does it attempt to load Windows, does the clicking start with HD access or does it start as soon as you turn the PC on.  Is anything displayed on the screen at all... until the clicking starts.  If your computer makes it past Post then I'm going with my initial gut feeling that your hard drive died on you.\n\nOf course, I've never had a motherboard short out on me so I have no idea what that would sound like... but it could be, I couldn't say.  Once again, this is one of these catch all problems where just about anything mechanical or electronic could be causing the noise.\n\nWell, since nothing works, this is going to be hard to diagnose.  Best guess is still a hard drive but now I'm going to toss in the processor, memory, GPU and well, any other hardware in your system.  Start removing components one by one and see what happens, save for the processor, I've never tried to boot a system without a processor but my guess is nothing will happen.  If that doesn't work, you're right back at square one.  Here's an idea, take your hard drive out, plug it into another computer as a slave and see if it at least works, don't do anything to it, just see if it is recognized, if it is, not the hard drive.  If you can rule out the hard drive you are looking at a dead motherboard and/or processor which will have to be replaced at least.  If the motherboard is fried, you'll have to check the other components to see what is good and what is not.

There are several problems which cause no display on monitor. \nMight be due to bad SMPS power supply... Check the back fan is working or not...?? if yes there might be problem with ur Mother board. u can check with the beep sound when starting PC...\ncheck the RAM & Processor....

it like this ..........from the facts you have given i can guess some things that i think has happened.........\n1.your video graphics card has a fault.....\nas i think it is not a full malfunction.but it is there...so first remove it from the comp and use a rubber eraser to wipe the attaching area to the mother board....(in the vga-)\nafter that chek...if it doesnt support it can be a  internal problem in the vga(ex-IC failier,so on...)\n2.your ram must be malfunctioning..i have experienced a ram malfunction..it was kind of the same...when i was working on the pc suddenly it restarts....then it became often.......\nfrom the data you provide i have a strong guess on the ram...check t by using it in another pc\n3.these may be simple but ..they wony alow you to work on your pc...chek the keyboard and the mouse cables....chek there ports..if the ports are not well attached or if the cables are damaged..it will make a short current and that short current effects on the mother board.......that will cause what uv told.\n\nsir........the best thing for you to do is chek above..but if your not familier with computers....get some help from some 1 you who knows the stuff..because it can be hasadoze in the system box....\nhope you will find a solution...\ncheers

It may be the display adaptor hardware in your PC? I assume its integrated into motherboard so do you have (or can borrow) a PCI display adaptor to test this theory? or better yet another computer or laptop you can test the monitor with to see if its the problem or its your PC... Good luck!

either reinstall your drivers, or buy a new monitor...\n\nwas there a power surge, or did you buy the monitor from another source?  many instances of this occurrance is the monitor is faulty and needs to be repaired/replaced...
