Windows 8 black screen after Login or the wake from sleep / hibernate and flickering screen

Hello

I have something of a nightmare with my desktop computer running Windows 8 x 64.

I did a bit of cleaning, unplug all cables, etc. and then reconnected everything later.

Since then, I've known the following questions: -.

After starting and going through the connection, I am faced with a black screen.  The monitor turns on, but there is no pointer.  However, if I clicked at random, it would open a Windows App out of the splash screen, which would then become visible.  If I moved the mouse to the bottom left, to get the splash screen, he would immediately go black screen on me.  He seemed to be refusing to display the splash screen.

With "display" black screen, I found I could get the Task Manager (Ctrl, Alt, Del) upward and there could access the desktop.  It would then execute as usual, but if I let it go into hibernation or even just having the power of the screen down, it would be black screen again, and I have to use the 'trick' Task Manager to retrieve the desktop computer.

Sometimes, using the Manager tasks does not always, because he'll sweep between the black screen and the desktop, alternating every 5-6 seconds.  I found through the process from the Task Manager, it stops doing this.

Now, I did a Windows 8 regenerate, without any change in the problems.  I made sure the AMD drivers have been completely updated (they were) and also physically checked all cables and cables are properly connected and the GPU / RAM etc are properly placed.

There is no error message displayed at any time. I have also disabled Fast Boot, nothing helps.

I examined a faulty monitor, but it worked fine for an hour or two at a time, until I got let go sleep or put into hibernation, and I'm at square one.  It would of course be a faulty GPU, or even a PSU failure, but I'm not convinced the symptoms are pointing to them.

For me, the fact it does not display the Windows 8 start screen after that Login or Wake Up is important.  It makes me think that Windows may interfere with the display in some way?

I can, if necessary, provide DXDIAG etc, and I "m hoping someone will have an idea of what goes wrong.  I have spent ages going through Google and others, but cannot find a solution to my problem.

Thanks for any help or suggestion you may have.

Conrad.

It solved!  Traded my monitor cable and all problems solved.  Guess he had a break or something in one of the lines.

Thanks anyway.

  • How can I PREVENT Time Machine back on the wake from sleep?

    I leave my machine on the work week and when I finished the night, I SLEEP there.

    In the morning, he has no need to backup first thing. But Time Machine insists on execution from the moment I have a mouse and he wakes up from his sleep.

    It was fine when it was new and fast, but now he is old and slow (especially - but mostly because I really push to the limit with multiple Safari Windows opens and executes a large number of software design at the same time, I have to do for work).

    My question is simple:
    How to tell Time Machine to does not have a return on the wake from sleep? or;
    Say this do not back up from 06:00 to noon? or;
    Is it a third party plug in that allows me to customize the time Machine more?

    Another idea on what just said or it to no return for even the first hour or two when it comes in the morning or even in any time to sleep during the day. Automatically.

    I also have my drive main external file mirroring AND use Super Duper once per day to fool the internal drive (I total plan control) AND back up all files off site (I total plan control). But, Time Machine is also always at hand to get it done. If only I had a little control over it, so she did not have the necessary step back up the minute I sit down. Significantly slow down my work time productive morning!

    Time Machine really shouldn't bog down your machine that badly.

    If Time machine running interferes with your ability to use the machine, then something else is wrong. It shouldn't affect performance in this way.

    If it's all just "annoying"... Well... Why is this a big deal?

    Maybe you should run a report Etrecheck and post the results here. If something is moving your system, which can help us identify what it is.

  • Satellite X 200-219 hang up the wake from sleep

    I got my satellite X 200-219 since April and he always showed the following behaviors but lately seems to have worsened.

    If I do nothing else that to stop completely the laptop after using it, the next time that I start it, it crashes some short but apparently random time after.

    I've never managed to imperically my theory, but it seems that there is a point of the catchment area about 15 minutes after what will be the shot, if I close the lid let sleep and then reopen it will probably be authorized, if however I turned off and make a cup of tea and open my back it is likely to crash. A power cycle and restart with the prompt "unexpected shutdown" was then held after the machine will be perfectly happy.

    I tried to use performance and error tracking tools to identify what is happening but to point out, nothing is connected, and I think that all who had not been emptied to disk is lost. I got it down before the opening of the session/finger drag but also I got most of the way by the, horribly slow, the boot process.

    I tried a number of other things, the upgrade to the graphics drivers, bios etc disbaling Aero, and all sorts of other features all without success.

    I am now at a loss as to what I can do next and don't really have any new ideas as to what may be the issue.

    Anyone got tips? Someone at - he seen this before?

    Hello

    I m no owner of an X 200 Satellite but I noticed hibernation/sleep problems on my laptop Vista too.
    For example my screen remained empty after waking from hibernation.
    I could solve it by the BIOS and update the graphics driver.

    Other problems have been resolved after installing some patches and Vista SP1.

    You never recover your laptop computer with the Toshiba Recovery CD and checked whether the hibernation issue has not changed?
    The fact is that a lot of problems is related to a BONE of garbage and the registry. It occurs due to mounting and dismounting 3 different third-party software.

    I always use a free tool of CCLeaner. It cleans my OS and fix if necessary registry entries.

    Unfortunately, I can't post an exact solution but perhaps tips could help you.

  • Computer laptop Windows 7 wakes up from sleep, Hibernate and shutdown

    I have a laptop running Windows 7.

    My laptop stop or switch mode standby/hibernation, only to wake up a second later. BUT, it does so only when my power adapter is plugged. I was able to disable this to happen before using the command prompt. After update, however, my laptop seems to have this setting reverts? It would be the third time I had to correct this problem. The problem is, I was stupid and did not write down the command, I used to fix the first time OR the second time and I don't remember what it is.

    When I use the command line powercfg - lastwake brings nothing to the top and nor powercfg - devicequery wake_armed. If it does not help things.

    Anyone know which command I would use to stop my charger to wake up my laptop?

    Hello

    Disable allow timers wake in power options

    Also uncheck allow this device out computer under powermanagement management properties - network - peripheral cards
    hope this helps

    Wake timers have already been disabled and "allow this device to come out computer" was already unchecked. Sorry, but none of those who have the problem. The charger is what wakes up my computer...

  • every time I erase content and settings on my iphone 6 after reset at the start of my phone and after crossing the screen as Hello > select language > Connect wifi > my iphone doesnot ask me activation lock even if my unit is also found on

    every time I erase content and settings on my iphone 6 after reset at the start of my phone and after crossing the screen as Hello > select language > wifi connection > my iphone doesnot ask me lock activation that says that your iphone is connected with the old apple ID, please enter the id and password

    I always reset on find my optional equipment please tell me how to activate locking activation so that whenever I have factory reset my phone with finding my camera so my phone always ask an old apple and password

    I do not understand your question, but let me go with what I believe. Looks like you entered in iCloud and erased all the content and settings on the iPhone, and once you go by assigning back up again, you do not see something that you expect to see, for example, a request for an Apple ID. When you go through the installation process to select the language, etc., it must, at some point, ask you to identify yourself with your Apple ID. are you not see this?

    It would be better if you try to describe exactly what you do again. Also, without the help of any sign of punctuation, it is difficult to track everything you ask. Try providing the steps of what you do, and then what you see when you get to the point that you believe that something is going wrong. You mention both an old and new Apple ID, which is rather confusing.

  • Fallout 3 stops working after the computer wakes from sleep

    Since the games for Windows Live 3 is out, Fallout 3 has never been the same. He used to work at best my GfWL and now her nightmare. Recently, after that I quit the game and put my computer to sleep, Fallout 3 will stop working completely after wake up. I try to start it and I get them all is a cursor with a small blue rotating light. What is even more strange, is that my computer goes into a State of semi who no longer meet this point where programs and keyboard shortcuts no longer work, but I can browse my hard drive. I try control + SHIFT + ESC to see what the devil but that causes Windows Explorer to stop working. CTRL + Alt + Delete does not work either. No matter what I try, once I start Fallout 3 after the computer wakes from sleep, I can't do the task to the top manager and I can't use my computer. The only way to get it is to hit the reset button or turn off manually. Can someone please help to get rid of this problem?

    Hi murphy449,

    1. did you of recent changes on the computer?

    2. the problem only happens when you start fallout 3 after the sleep mode?

    3. are you able to wake the computer quits successfully sleep mode?

    4. What is the version of Windows installed on the computer?

    Method 1

    I suggest that you manually download and install the latest drivers for display on the computer card and check if it works.

    http://Windows.Microsoft.com/en-us/Windows-Vista/update-a-driver-for-hardware-that-isn ' t-work correctly

    Method 2

    If the previous step fails then I suggest that you try the clean boot procedure to check whether a third-party program installed on the computer is causing the problem.

    To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

    If the previous step fails then I suggest you check the observer after return with details and events for the cause.

  • Aspect wide photo after you transfer the images from the camera

    Original title - aspect wide photo after download

    After you transfer the pictures from my camera to my PC, subjects are not as the original photo taken.  People who are really thin show also stubby. I used another PC and downloaded normally photos.  I used the photo of different programs, from Kodak, Roxio, windows Photo Gallery. I put my card directly into the PC with the same results. I tried to change my video setting and updated my NVIDIA card driver. Change the size of the photo doesn't do any good change just the measure of perimeter. I know that I can edit the photos, so people watching more thin but can you imagine doing that in every pic I take. I hope someone can help

    I finelly solved the problem by playing with the resolution until I found the appropriate settings. How to change the setting, I don't know, but as long as it works I can live with that.

    Hi George,.

    From the description of the problem, it seems that the computer would not wake from sleep when you close the lid and open it again. I understand the inconvenience.

    Let us, try to perform the following methods and check if it helps.

    Method 1: Run the troubleshooter of power
