Screen guard randomly goes black for a few seconds

At random times, but especially when I'm using outlook or to access the internet (not always), my screen will go black for a few seconds, then back on, but with the slightly distorted screen. I have connected a new monitor to the computer to see if it was a problem with the monitor, but it always does with the new screen, so I know it's the PC itself. How can I fix it?

  • Screen goes black for a few seconds while playing games

    I come here who need help, I was this problem for some time and were not able to find the solution on my own.

    The question:

    Sometimes when I play games my screen will go black at a random time for a period of time (sometimes only a term of 5 to 10 seconds, other times up to a minute) and then gets himself and I am able to continue to play. The sound continues to play during the blackout, but I have no control of my computer. Nothing does not and cannot use commands such as ctrl + alt + delete. Sometimes, when my computer is recovering from the black screen, I hear the fans on my GPU boost up to about 80%. I put in MSI afterburner to increase my fan speed as the temperature of my card. Sometimes during recovery from a black screen, my fans will increase from 25% to 80%. Then, there is 80% for the rest of the time until I reset my computer. Once my computer is reset, my card will be 25% more.

    Contextual and computer information:

    This question is not started past until I installed and new graphics card and reinstalled windows 7. The GPU has been tested before I reinstalled windows 7 and everything is perfect. no power outages. I reinstalled windows 7 because I had an SSD.

    Here are my features right now:

    PROCESSOR FX-8350
    Card MOTHER Asrock 970 Extreme3
    RAM (2) 4 GB DDR3 1600 and (2) 8 gb DDR3 1866
    SSD 120 gb w / windows 7 installed top
    GPU Radeon r9 290 (upgrade a radeon 6950 which took perfect)
    Corsair power 800w

    a few last things to add that can be useful:

    -I did not black when using my computer and do not play games screens.
    -J' usually have low games such as the League of legends. who are not too intensive on the gpu
    -When I insert in the UEFI, my RAM displays all the sticks clocked at 1600 MHz. Even if 2 of my poles are 1866.
    -My gpu never went more than 74 degrees since ive installed, so I don't think its an overheating problem.

    If you need more information, let me know and ill be happy to provide it. Any help will be MUCH appreciated. I get crazy at this time because I can't figure this thing out lol

    Thank you - Nick

    Thanks for the help! I actually just figured it on mine.

    Here's what the matter was.

    Afterburner in fact has not been increasing fan speed, I had put in place as the time grew. Tried running my r9 290 to 60% of the speed of the fan. Never had a black screen again. I'm glad that I can play games now. Only thing that sucks is my r9 290 is a powercolor card that uses a unique suction fan and blows air on the side. THE THING IS EXTREMELY NOISY at 60% lol but I managed to get the r9 290 for only $200, so I can't complain.

  • * Media Player stops. My drive stops, then recovers itself after a few seconds. Screen goes black for 1-3 seconds, BUT Audio continues!

    I have Vista Ultimate, but I'm not very smart PC!   When I try to watch a video clip, etc., SEE above EDIT.  My drive stops, then recovers itself after a few seconds.  Screen goes black for 1-3 seconds, BUT Audio continues!  Then Visual back for a while until that the same thing never happens again anywhere!  Also the FAN spins-up like a jet plane taking off!   Help, please.  Thank you.

    Hi Peter,.

    1 have had any changes made on the computer before the show?

    2. which media player you use to play the video?

    3. the problem occurs on all the video clips?

    I would say as update you the video card drivers and check if the problem persists:

  • Equium A100 - 027 Vista: the screen goes black for just 1 second

    I was wondering if anyone here can tell me what is the problem with my laptop. That's all new Toshiba Equium A100-027. Quite often, my screen will turn black for just a second, and then it will return to normal again.

    I changed my power settings, so it is not because of the screen laptop will. Most of the time, it's going to happen when I run the program in full-screen on real player, but it happens when I play mahjong titans which is included in microsoft vista.

    HM, just a small suggestion to check if you have a hardware related problem or some software:

    Connect your laptop to an external monitor and see if the problem still occurs.
    If the problem occurs with an external monitor then check that you have installed the software and try uninstalling the last installed software, perhaps the best will be step by step.

    So if all else fails, then try a recovery.

  • HP HDX 16 t Premium - screen goes black after a few seconds

    Just today my screen started going black out of no where (when I played StarCraft 2, a high-performance PC game.) Now, he's doing regularly (after a few seconds to about one minute.) It's almost as if my computer goes into mode 'sleep' but I can't wake up. This happens less often when I put the brightness of my screen on a lower setting, and tends to fade before going to black instead of going just instantly black. I also have an external monitor attached, and when my laptop monitor goes black the external display remains lit and fully operational.

    Some things to note:

    -The power cord is attached and plugged in, and turned on my computer.

    -J' have a cooling block and my computer is not overheating.

    -The battery has full juice.

    -J' tried to restart my computer several times and still have the same problem.

    -C' is the case even when I'm not running high performance games or programs.

    -My settings to be able to tell my computer never sleep, decrease intensity after 10 minutes (5 minutes for the battery) and the screen turns off after 20 minutes (15 minutes on the battery.)

    -When the laptop screen is on the brightest display settings, it seems to be flickering.

    I did some research and it seems to be a problem with the LCD capacitors going bad. If anyone can check this? If this is the case, is there a way I can replace and where would I do my shopping?

    Thanks in advance

  • White screen for a few seconds in El Capitan

    Hello

    Since I updated to Yosemite to El Capitan (10.11.2), I get a white screen on a regular basis for a few seconds and the normal back.

    I use a MBP 2011 end. I read somewhere that it could be due to an incompatible application, but for the moment I could not identify any.

    Thanks for your help!

    When you see the white of the screen, note the exact time: hour, minute, second.

    These must be run as administrator. If you have only one user account, you are the administrator.

    Run the Console application in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    The title of the Console window should be all Messages. If it isn't, select

    SYSTEM LOG QUERIES ▹ all Messages

    in the list of logs on the left. If you don't see this list, select

    List of newspapers seen ▹ display

    in the menu at the top of the screen bar.

    Each message in the journal begins with the date and time when it was entered. Highlight date back to the time you noted above.

    Select the messages entered since then until the end of the episode, or until they begin to repeat, whichever comes first.

    Copy messages to the Clipboard by pressing Control-C key combination. Paste into a reply to this message by pressing command + V.

    The journal contains a large amount of information, almost all this is useless to solve any particular problem. When you post a journal excerpt, be selective. A few dozen lines are almost always more than enough.

    Please don't dump blindly thousands of lines in the journal in this discussion.

    Please do not post screenshots of log messages - text poster.

    Some private information, such as your name, may appear in the log. Anonymize before posting.

    When you post the journal excerpt, an error message may appear on the web page: "you include content in your post that is not allowed", or "the message contains invalid characters."

    My sons laptop has problems - try to turn on and it would maintain a black screen for a few seconds and then turned off and turn and repeat until I've done a hard stop.  I am able to navigate to the top after repeated attempts.  I could take a quick and complete hard drive test and it passed... Finally, I restored to factory and spent the last 8 hours going through the update process.  It works fine and restart without problems until recently - I followed the instructions to reboot to perform an update, but he had served in the "shutting down" mode for almost an hour I did a firm hard down.  It took a few attempts so he could begin after that, and when I did I had a message on the svchost.exe and thought that might have something to with him... found a site that has a download that is supposed to fix errors and am curious if that is recommended or whether there is another solution or possible make my misfortunes.  The site is: http://www.exe-error-advisor.com/svchost-exe.  I don't know what's happening - the computer works very well when it turns - to be fair, I did also made an update of "HP Total Care Advisor" who has nothing and after I rebooted I could not make it work...

    Hey everybody.

    I recently changed my HARD drive and did a reinstall fresh, as previous was damaged. What is happening now is that whenever I have connect or disconnect the cable the screen goes black for a second. There is no real consequence of this, I'd rather just if there was an option to make it happen.

    Then, give a shout someone if you know how to deal with this.

    Hello

    > I have recently changed my HARD drive and did a reinstall of fees
    You have installed Windows from Toshiba normal Microsoft Windows disk or recovery disk?

    To me it sounds like that, you forgot to install the display driver. Also check the Manager of devices for the yellow exclamation points or unknown devices.
    Make sure that correct display driver is installed. You can download the latest version of Toshiba's official website:

    Hi guy,

    I think that it of difficult to say exactly why the screen / the game freezes for a few seconds during the game. There are too many different factors that can affect the game, laptop performance.

    For example the GPU performance can be clocked down due to a higher temperature or memory might be full and the data has be moved to the HARD disk using the paging file.
    Maybe the CPU's load a few seconds due to various processes that run in the background (anti-virus, etc.)
    Maybe its GPU driver problem. Who knows

    I think first of all you must disable all security and antivirus software that could run while you play a game. But do this only while game.
    You can also try to reduce the graphic details in the game settings.

  • AL1716 screen turns black after a few seconds. If I turn the monitor power off & on again, it works - 2s

    The monitor worked fine for a few years, so is no longer under warranty. I was about to throw.

    Then the monitor I bought to replace, was damaged on the way to the group practice site.

    Now, I hope to fix the Acer monitor.

    When the computer starts, and a new screen loads, the monitor it shows for a few seconds. Once the computer on the desktop, if I turn off the monitor and turn it back on, it displays the desktop perfectly for a few seconds.

    The monitor I replaced it with also works very well with the computer. He collided with another device, when the car in front of me stops suddenly and there is a piece missing from the screen in the lower left corner. It looks like modern art in the lower part with some of them white and black and a few vertical lines and horizontal lines. I can continue to use it, since what I need lies in the upper part of the screen. I learned the keyboard command to shut down the computer. The windows key, followed by the right arrow, followed by the Enter key.

    I watched a few videos for repair of monitor on Youtube.

    It seems that the capacitors are the typical element which spoils first.

    So I guess I'll break the front off the monitor and see if the card has the capacitors top of the pop up. I can use capacitors with the same intensity of micro-Farouk and the voltage equal or better than the other monitor.

    I've recently learned step secret beginning of successful welding.

    You must have a clean tip.

    When you clean the tip of the soldering iron, it should have the appearance of copper. If weld does not stick to the point, it is not clean enough. I used a wet sandpaper dry and scoured it. They are sold with a protective coating that must be removed. If it is not removed it clogging the tip.
