If the monitor actually says "no signal" chances are your graphics card is set to output a videosignal your monitor doesn´t support but windows may have started up normally. You just can see it. I accidentally did this once and had no choice but to reinstall windows. Which in turn required me to format my hard drive. Don´t do that just yet. Someone else may have a simpler solution...

Did you have a power outage?  Surge perhaps?\nSomething took out the power supply right?\nIf you aren't getting any kind of beep code or anything and everything seems to be reacting normally.  The very first thing I would do is check to make sure the monitor didn't get toasted!\nAlways verify the monitor isn't fried before you go to the MB and other internal parts of the pc for troubleshooting a video related issue.  Did you get responses from the hard disk, or cd rom after the power supply was replaced?

If all the connections are checked out and allright, you should try to contact the manufacture of your monitor.  It does not look like a problem with your computer or vedio card.  But monitors can often be flaky.

Hmm.....If its not the monitor, it's definitely the video card. If you have another computer, try swapping the cards and see if it works. Hope it helps.

Is there any beeping when you start up your PC?  Have you made sure that the cable is securely connected on both ends for the monitor?\n\nGenerally if ram has bad sectors in it, the PC will still boot up.  I am not sure if this is the same for a video card, but I think so.  Have you made sure the video card is in its slot all the way?  I would open your PC and check.  Oh and have you recently installed any new software or hardware?

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!

Could be a bad monitor - sometimes that happens.\nOr there could be something that's causing interference such as a cell phone charging nearby, a fan running etc...

Just press any of the keys on the keyboard. Even then if ur monitor is not on , then check the power button of monitor.\nHope it will solve the problem

Make sure the video connection on both ends, the computer and the monitor (some do come out) are tight.  If so try a different monitor.  If the new monitor is also yellow then it is your video card.  If the new monitor is fine then replace the other one.

I'm thinking it's a power supply in the monitor.  You might want to try another monitor to assure yourself that the problem is indeed with the monitor.

are you getting power or not. i would first check all the cables to see if anything are loose. i would also check the power supply. and also would look in you motherboard book to find how to reset the bios.

check the connector for the monitor\ntry disconnetcting the game and on the PC as usual with the Monitor on. If the monitor display fine.\nif after connecting your game, the problem starts, then your have a problem with one of the folowing:\nVideo card,\nRAM,\nor Power Supply,\n\n\nfor further advice contact\nalexzubi AT yahoo.com or www.freewebs.com/zion23401

so the power sign is green, but when you turn it on its just black? well all your screen is is a monitor connected to the cpu, so you might have power failure to the monitor, but not the cpu. its the same as when your tower is on but the screen is off with a desktop.

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

Check the power supply cable (the one with the 4 pins).  It sounds like it just isn't getting any power.  Even if there's something wrong with the jumper settings or the I/O interface, it should at least spin up.

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

ur monitor might be out dated. I had a ol packard bell monitor that took 30 min to warm up and then it was blurry and all messed up becasue of it's old age.
