Black screen and mode standby with the message "no signal".

Correctly, it's... kind of weird, I use my computer and the monitor for a year or 2 now and don't never had real problems. The thing is that when I got home last night I found my black screen and standby mode (as if the computer was turned off (which it wasn't)). I thought that the reset will solve the problem, and so I did and didn't get the message "no signal". All tried, reconnecting cables, reset several times I could count... nothing helped for awhile.

At any given time during one of my restarts it reworked all of a sudden no aparent reason. So going on my daily buissiness I want to get back in the saddle, when I accidentally hit the side of my computer with a book and the screen went to 'no signal' again. Just tried again and even used my cell phone to check if the monitor was working,... now comes the weird part,... also on my laptor monitor is having problems with "no signal", but only when I do my main screen. It works as a secondary screen, but I can't get the context in which to work. (finding that I'm guessing that this problem is not related to my normal computer, but I'm not sure).

I am running vista and got a nvidia 8800GT graphics card. Also, I noticed something that is at any time using both the hdmi cable on the graphics card or using the socket with the internal chipset of my computer makes no difference. in both cases, I get "no signal" and the screen goes to sleep... Is there someone who can help me and tell me what probably is the problem here? I'm really looking forward to the answers, thank you very much for your time and effort.

Hi Ron Suykerbuyk,

If you are comfortable, then try to remove the CPU cover and check if the graphics card is well connected to the motherboard. Even if it is connected correctly, you can try to reconnect the graphics card and check.

Hope this information is useful.

  • Invalid product key, left my computer with a black screen and a cursor of the mouse on the boot.

    A few days ago, I tried to upgrade Windows 7 Home Premium (64 bit) to Windows 10 using the free update. Installation hung at 84% for 2 hours, then restarted, was unable to recover the installation and then could not get back to Win 7. This left us with a black screen and a cursor of the mouse on the boot. The computer would remain in this State for about 10 minutes and then reboot and repeat.

    Fortunately, or so I thought, I had a few CD Windows installation backup from the back to the era of digital river. So I thought I'd install fresh on my empty partition, copy my files and data, and then format the partition with the installation broken on.

    I did, but now he tells me that my product key is not valid and cannot be activated. The product key came on a real label on the PC when we bought it.

    The key is for X 16-96072. I installed X 17-58997 (Windows 7 Home Premium x 64 with SP1 (u)). I don't know what is the problem with the key? Should I have installed without the (u)?

    One key 25 digits grouped in 5 sequences of 5 characters not X 17-58997.

    To analyze and solve problems for Activation and Validation, we need to see a full copy of the diagnostic report produced by the MGADiag tool (download and save to the desktop -http://go.microsoft.com/fwlink/?linkid=52012 )
    Once downloaded, run the tool.

  • my screen shows a black screen and says to enter the system password, how do I reinstall windows if the pc is back to factory settings and wonder a system password

    Don't let me do anything, as soon as I turn on my pc, it goes to the black screen telling me to enter the system password

    It looks like your BIOS password "may" be set.

    What brand of computer do you have?

    If you have an antistatic grounding cable and are comfortable opening your case, you "can" be able to follow a procedure in the manual of your motherboard to reset such password.   If you choose to do so, please be careful because you do so at your own risk.

  • Computer has a black screen and does not show the normal startup logo and more

    The computer that I use usually works well, until the next day, the day that I used it, ruined everything. My computer shows not the Windows 7 logo normal at startup, but instead, a bar with green lines in movement like the ones you see in older versions (Windows Vista), but now only the bar and did no logo in it and after starting does not display. It shows a completely black screen, but it makes a noise like the sound when she welcomes you to Windows 7. I tried safe mode and disabled the NVIDIA GeForce GT 220 graphics card and the screen works, but he is stuck at 800 x 600. In addition, the start screen is always the bar. How can I fix it? (Tried updating the gpu but still displayed black screen)

  • Start the computer to black screen and the computer runs hot

    original title: sick Vista laptop

    My daughter portable computer began acting strangely very yesterday.

    Once connected, I get a black screen and a cursor.  The system seems to work at full speed, because I can hear the fan, and it runs very hot.  No matter how long it sits, the desktop does not appear.

    I can use Ctrl-alt-del to display the Task Manager.  The list of processes is limited to the process of the current user, and none of them use important CPU. If I click on 'See the process for all users', taskmanager freezes and I have to disconnect to get rid of him.

    Using the Task Manager, I can kill the process Explorer and then start it again, date at which I get my desktop.  However, it is still running hot and noisy.  With the help of SysInternals ProcessExplorer, there is no process using any important CPU.  Most of the time CPU is reported as inactive.

    I don't know what to think.  A boot loader took over the system?  A hardware problem?  OS corrupted files?

     

    Follow these steps to try to solve your problems of boot.

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

  • Windows 8 black screen and the cursor after the connection

    Hello. I tried to upgrade to 8.1 Windows 8 Windows and it is stuck on like 3% for one hour, so I just rebooted the computer and he returned to Windows 8. I'm going to sleep and come back the next day and go on my laptop and it auto connects me and it goes to a black screen and I only have the slider on the black screen after login. I don't see the start menu, but I receive notifications for as sticky keys or any other notifications lights. I turned off my computer at least 20 times, took out the battery, empty the battery and tried to boot in safe mode with no luck. It is unlikely that it is an internal problem, because if I leave my computer alone for a few minutes, my screen saver photos appear. If anyone can help me solve this problem or help me get in easier safe mode would make things less stressful. I have an Acer Aspire V5 - 571 series. Thank you.

  • Help urgently needed! -User profile takes a long time to load and the rest of the screen with the message "Please wait loading profile service user.

    Hello

    Every time that connect us to servers of TS farm, the profile of the user load for a long time and she stays with a message "Please wait for the user profile service" for longer than 5-6 minutes. We work in two areas which is configured as "an endorsement of forest transitive way." The domain (domain A) with TS farms hence connect us a cross forest profile disabled so we cannot load the roaming profile in this area, whereas another domain (domain B) roaming profile user's roaming profile.

    Also in the directory the Active directory of the domain B, TS/RDS settings is enabled for the problematic profile.

    TS / RDS--> roaming profile path and TS home folder is configured. TS/RDS settings is configured because we use other farms of machines/TS citrix other than the one in which there is problem.

    When disable us TS/RDS of the directory settings active directory domain B, then it is extracted to improvement in time. But we're in a situation were we cannot disable TS/RDS settings as we use other Citrix machines also. So we tried configuration GPO in A TS domain as

    Which allows to "allow only the local user profile".

    Allowing 'profiles itinerant Prevent password propagation to the server.

    This allows to "Allow asynchronous user group policy processing when you connect via Terminal Server Services"

    But still, there is no improvement in the time taken by the server to connect. What is the adjustment to make in the field of A TS, such that he will not try to charge the roaming of the B domain user profile, even if TS/RDS settings for the user profile are configured?

  • After logging on my Satellite Pro only black screen and the cursor are visible

    I have a windows vista pro (PSAASE-00G004GR) satellite after turn on and typing the password for windows vista, the screen goes black but I see that the cursor moves & because it seems that the hard drive also works in th background, but I can't see anything except the mouse cursor , I tried to boor with other options (LAST WORK safe MODE KNOWN FEATURES... etc) but it's still the same only black screen and the cursor...

    I do not prefer the product cause of my data recovery on this subject, any ideas?
    thnx

    Hello

    You have the Satellite Pro A100 PSAAS hmm if you want to save your personal data, I recommend to remove the portable computer HARD drive and try connecting it to another computer via an external USB HDD controller. These cases of 2.5 HARD disk are not expensive and you can buy it in every store of the computer.

    Then you could try to recover the laptop delivered together with the Toshiba Recovery CD.
    But wait; have you tried to connect the laptop to the external display?
    Check it!
    Maybe you could see something on the second screen.

    I think that this procedure could be useful to clarify what s wrong.
    To me this question looks like a small little dysfunction of the FL inverter.
    In this case the installation of the new operating system will help you not to solve this problem.

    But who knows the verification is necessary to find what could be wrong.

    Good luck and bye ;)
