Screen Shows Message: No Signal And Screen Stays Dark?
Dec 8, 2012
started recently, when I boot my PC, the screen shows message: no signal and screen stays dark.However, in the background W-7 is loading, but in order to get the video functioning, I must restart the PC, turn off the screen, wait till W-7 loads somewhat and (like after 10 sec.) turn the screen on and everything is OK.Monitor is NEW Video card too, I tried with a second one, same problem...My question is, is this W-7, main board, or something else related?

I have installed the latest drivers, reinstalled the program, and all that jazz and the problem still persists. Pretty much when I minimize or exit from a game I play called EVE Online, my LCD remains really dark. Kind of as if someone turned down the brightness really low on the LCD. I've figured out 2 workarounds but they aren't fixes.
I simply log out and log back in and the display brightens to its usual brilliance or I hit Ctrl+Alt+Del and it has the same effect. But once I maximize the game and minimize again the screen darkens once more. Oh and in-game everything is perfect, it's only once I go to the desktop. Any ideas? I personally think its a something wrong with the refresh rate but I ahve no clue as to how to fix that.
I have attached my DxDiag results.

If I let the computer sit unused, the screen goes black, as most monitors would; however, the screen stays dark when I move the mouse or hit buttons or something. Similarly, if I close the lid of my laptop when its turned on, and then open the lid, the screen stays black. Not only that, but when I closed the lid of the laptop, the computer never turned off. It was still running.I reset the power options to default as well, so there is nothing wrong there. Perhaps I should also mention that the screen successfully turns off and on in safe mode?
edit: Just tried a system restore to two weeks ago and the system crashed. Both times.

I am facing this problem, mostly while playing games and sometimes even when operating computer normally. Earlier I used to get BSOD but now it comes rarely. I tried almost everything but wont able to solve this problem:
- Formatted my computer
- Changed OS
- Reinstalled OS
- Even changed my monitor

On my monitor it seems like everything is too bright, as in places that should be pitch black are a bit too light. For example: on my iPod, even with full brightness settings everything looks normal, but on my PC's monitor it just doesn't look right.I calibrated color and setting gamma way low really helped, but my contrast is set to full, and my brightness is 75.The strange thing: when I ran Crysis 1, it fixed the monitor color! So I know the darn thing is capable, I just don't know how to.When I closed down Crysis it went back to normal.

my laptop's screen keeps going dark after being on for only a few seconds. When the screen goes dark, I have to move my mouse around to get the screen to come back on which it usually does. After a few minutes of doing this, my screen stays on. I am running Windows 7 Ultimate 64 bit. I do have McAfee anti-virus protection. I just recently ran a virus scan which came up clear of any viruses. I also tried adjusting when the screen goes dark

I have a 10 month old Acer 5820t laptop running win 7 home premium. About 6 weeks ago, the screen started going dark every few minutes and it has gotten worse. I can see the image faintly and by pressing the display brighten button can get it to come back or sometimes have to close and reopen lid it will come back. No external peripherals are connected. The Intel HD graphics card has the latest driver installed. The screen saver seems to work but the display will also go dark when the screeb saver is running.

During the day, if we leave the computer alone, screen goes black, after a while, fans turn off. Wireless mouse wakes it up just fine. Fans startup before the screen is completely ready to go. During the night, the screen is dark, but the fans almost never stop. Why?

My laptop screen stays off when I close the lid. I set the laptop to 'do nothing'(turn off the screen), when I close the lid. When I open it, the screen stays off.The only way to fix it from here is to either turn it off or to put it in sleep mode (with my designated button). Everything still works, its just that the screen doesn't turn on.

This morning, Windows installed 5 updates, which I had postponed from yesterday. It told me to reboot but when it did, it got stuck at the Press ESC point. There was no disk activity. I turned off and rebooted again several times with the Windows Repair disk in the DVD drive. I was able to run the startup test but it said it couldn't repair it. The log said the the fault was caused by a critical update. I went into System Restore, but I am unsure of the options. It showed a screen with all my partitions already ticked, including the Windows boot partition which was greyed out. Am I supposed to leave all the partitions ticked, or if I don't, will I then lose those partitions?
I currently have the Wondershare LiveBoot 2012 DVD running but I'm not sure what option I need to use. Recover MBR, Recover Boot Sector, or Recover Boot files, or all of them?

I am having an issue of HDMI working during PC boot, but TV loses signal just before Windows 7 log in screen comes up (TV shows "No Signal" at this point). If I use VGA to connect PC to TV, everything works fine. [code] One thing I noticed is that Windows 7 device manager sees my TV as a "Generic PNP Monitor". I have no idea if this is connected to my issue or not. The Intel website says my drivers are up to date when I run their update utility. The Intel Graphics utility on my PC sees my TV as a monitor, not as a TV, but it does list the correct model # (M260MV).I've tried connecting both the TV with HDMI and a PC Monitor with the VGA cable and the computer would only detect the PC monitor with the VGA cable.I have read on an Intel site that others with the Core i3 CPU had similar problems so this may be a CPU/CPU driver issue, but as I said, the Intel Update Utility says my drivers are up to date.

W7 will start up, load files, and then stay at a black screen with a mouse. I think that the hard drive may have gone bad, and when I did a memory diagnosis, I have found that there is bad memory with my main hard drive. I do not have the original disk, nor can I access any of the files. I tried system Recovery, but it would not list W7 as an option. If someone knows where I could find those drivers to load onto a disk, that would be great. My computer is a Dell Studio 1535.

I have Windows 7 on my laptop and after I start it up and enter my password to login to windows I have to wait another 10-15 minutes for my desktop to appear. It's just a black screen, but the kicker is that I can move my mouse and see it on screen.

I have a
Lenovo Laptop Thinkpad Edge E520
8GB RAM
Intel CPU B960
Pentium Processor 2.2GHZ
Recently when I have powered up my laptop it occasionally doesn't load properly, the screen stays black. You can hear the laptop working fine but you cannot see anything. This happens once or twice a week, I usually hold on the power button for 5 seconds, then reboot and it resumes my hibernate settings as usual. Could this be because I always hibernate my laptop?

Over the past few months I began having this recurring problem where the computer goes into sleep mode, next I click the mouse to wake it and the lights and fans go on but the screen stays black. I then have to perform a hard restart where I was usually getting the "start in safe mode" screen, but lately I have also been getting BSODs.

I recently built a computer for my first time. It was running fine whilst playing Arma 2, dayZ and dawn of war 2. I then installed Star Wars The Old Republic and everything went on fine until I went to play the game. The screen went black and the no signal message came up on my tv.
I could not do anything so I just turned my computer off and then back on again. When I then went to boot again in Normal mode, it just shows the windows logo and then does the same thing.
I have tried booting it in safe mode, and this works fine. I don't think it is anything to do with my monitor as it works in safe mode and also it's my tv which works with DVDs and anything on TV.
Could it possibly be something to do with the drivers? Although I have been playing other games fine until now. Or could it possibly be something such as a corrupt file or the game installed something else which won't work?
Someone also suggested that it might be something to do with the power going into the computer? They said it could be putting too mcuh power into it and it would cut out.

My problem is that if I connect the computer via DVI to a display it functions normally, but when I hook it up via HDMI to my Flat screen, it doesn't show the splash screen that gives you the option to enter bios. The screen just stays black until the windows welcome screen(win 7 64bit) comes up, then it acts totaly normal from that point. When I try to press the del key during the boot, I believe it is entering the bios, but the screen remains black so I can't see anything. I am guessing that the MB is not sending the signal to the Flat Screen until it loads windows, but can't find out anywhere that confirms that or what to do in order to resolve it.

I have a white box tower with a ASUS P5KPL-CM Motherboard I turn it on and I get a black screen, no signal to the monitor,so I plugged in my old Sony tower and the monitor works. So it's not the monitor or the cable( switched them a few times by now) I believe it is the new tower. I think it might be the VGA card but know little about these things. Manual says it is a Intel Graphics Media Accelerator (Intel GMA 3100).Or could it be something else? By the way I have Windows XP if that makes a difference.

I turn on the computer, goes past the bios screen as normal, does the windows loading screen as normal, then the screen goes black and the "No Signal" message is displayed.
Now, here is why it is different. I type in my password and press enter, without being able to see and wait for the logon sound to play, then if I unplug monitors cable, I hear the noise of windows telling me a device has been disconnected, I plug it back in again the device connection noise then plays and low and behold, there is the desktop.
I have been running Windows 7 build 7100 for roughly about three weeks until this started happening about one week ago.
MONITOR: ViewSonic VX1932wm
GPU: Sapphire HD4850 512mb
Also, I have noticed too after logging, randomly Aero will disable itself, I have to open the 'Personalize' option and run the troubleshoot to get it to fix itself again.
I assume this is the correct section, as I am experiencing visual issues. Apologies if this is not the correct section.

So my issue is with all my full screen games, after a few minutes to a few hours the screen go's black and an error pops up on screen.
Signal out of range set to "1680 X 1050 @ 60hz"
Normally I would just put it to those settings, but the issue is these are basically my setting in the nevidia control panel my settings are exactly that. The only thing I could see is the advanced display settings are 59hz. But you can't set it to 60 because windows 7 rounds down instead of up now.
[code]...
