Splash screen, blurred or distorted after the PRAM reset

Hello

I had several problems lately with my MBP 15 inch 2011. Install the new OS X versions and updates point makes three beeps and reboot several times in quick succession. Those point updates will then appear as installed six times in the list of the updates installed the app from the App Store.

Thinking this could be an issue that could be fixed with a STROLLER reset. I realized and noticed that the after reset the PRAM, the splash screen is blurred. Attached photo:

Even once more my AMD GPU degrades?

Thanks in advance.

5 beeps indicates a RAM problem.

  • HP Pavilion dv6000 (Vista) starts with a blank screen with a cursor after the original hp logo screen.

    HP Pavilion dv6000 (Vista) starts with a blank screen with a cursor after the original hp logo screen.  Cannot get it to boot Windows.  Any thoughts on next steps?

    I remove the hard drive and attach it to your desktop and use the host operating system to run a check disk on your drive.  The laptop goes hard disk looking for instructions to start and he does not see the correct code.  This is probably due to a damaged boot sector.  Another idea is that your bios has changed and you have changed the SATA from AHCI to IDE type somehow or vice versa. You also left a non bootable disk in the DVD/CD drive.  Remove all disks from your DVD.

  • App installs on Z10 when the icon & Splash Screen images are added to the handle Bar

    HI - don't know if it's an unusual question, but my app not install/load on my Z10 when one or both of the pictures icon and Splash Screen are added in the descriptor of Bar.  I development mode and have an installed debugging token and it is still valid.  The strange thing is that the application will be installed on the Simulator without problem.

    If I remove the splash screen images & icon in the Bar descriptor file, the application load on my Z10 with success.

    The images are the right size: 114 x 114 px for the icon and 768 x 1280 px for the SplashScreen.  The Momentics IDE accepts two files by activating beside them.  I also tried to add the images to the Q10 & PlayBook and still no luck with this loading on my device.  I even tried to go back to the image by default for the icon, and who does more either.

    The error I get when trying to install my application on my Z10 with icon images & Splash Screen is:

Please be aware that such a restore is not aware of the partitions on your internal drive and can erase your internal drive.

  • Black screen with blinking cursor after the passage in MSC mode

    I followed the recommendation to disable startup secure in the Bios then move the UEFI Bios to the CSM. But when I go to set up what I see is a black screen with a stable cursor in it. And it doesn t go in the Bios.

    The black screen remains.
    I turn off the laptop and once again now, but I still have a black screen with a cursor that is stable and that s it.

    It's like that and it doesn t go to windows even go into the Bios, I can t.
    What should I do?

    Help, please...

    Hello

    After the passage of the CSM and disabling secure boot UEFI mode, you will not be able to boot from the HARD disk as the installation of Windows 8 requires secure boot and the mode of the UEFI.

    Now you can boot from the disc or other media bootable (USB flash key) to install the Windows 7 system.

    I guess you've made these changes installed Windows 7. Right?

    By the way: what model of laptop you have exactly?

  • Screen does not light after the start, but after standby on Satellite M100

    Hello
    I have some experience with computers and laptops, but this problem exhausted all of my knowledge.
    My girlfriend has a Toshiba Satellite M100, PSMA1E. He currently works on Windows XP, SP3.
    The laptop has always had problems closing/stand bye. He would stand bye and the screen would not. She would usually be manually turn off (holding the power button) and restart.

    Same thing happened last week, but with me. I turned off the power button but when I turned it on the screen was completely black. After a few attempts, I realized that everything worked; I could hear the usual audio files and XP Boot, but there was no way I could get the job of the screen.

    The strangest thing is that the CMOS/BIOS, one with the Toshiba logo settings screen, also does not appear. If it's an OS problem, I thought that I would be able to access the BIOS at least, but it does not work. FN + F5 does not work.

    Then, strange yet something happened. I was turning it on and off with keyboard shortcuts and I realized that if I put on stand bye using shortcuts and then go back on the screen turns on perfectly well (there is a cause of adjustment resolution icons are irrelevant, but it works perfectly fine).

    From that on I tried everything I know. Update the BIOS, all Windows XP updates, all Toshiba QuickFix, cleaning the registry with different tools, uninstall and reinstall the video driver (ATI Radeon X 1400) utility, shortcuts keyboard, power saver, tools hardware Toshiba, looking to start up programs, services, everything I could possibly think off.

    What intrigues me is that the Toshiba start screen will not be displayed. I can't access the BIOS, but I tried to restore the standard values of the BIOS with Toshiba hardware tools. It did not work. I don't even know if reinstalling XP will work because whenever I turn it on it is all black and I have to make the stand bye / Tower on Tower.

    When I have it plugged into an external monitor, I could see all starting the process (initial screen of the BIOS and Windows). I then tried to access the video driver display configuration but it would show only the external monitor. It would only detect the laptop screen after a stand bye / turn back on, and then it worked perfectly: the screen two screens simultaneously, extended, everything. Ah, changing BIOS selection automatic the LCD + external monitor does not work.

    I am really puzzled here and I can't understand it. I really don't think it's a hardware problem, because the screen works 100% after the stand bye. I guess that XP is do something during the closing down that completely 'stops' my screen, even after starting, and then I can only turn it on with the thing stand bye.

    Any help would be really appreciated!

    Best,

    Hi guys

    I had a similar problem on a series of Satellite A200 and I could solve works to update the BIOS and update the graphics driver.
    In addition, you must make sure that all available MS fixes and patches have been installed.

    Unfortunately, but that's all I can suggest. If the problem persists and you would not be able to solve update components then an ASP needs to check.

    Good luck

  • I downloaded an update and restarted my computer, received the blue screen of death shortly after the computer restarts. Now it does not start

    I don't know when the downloaded update, the computer has been restarted on September 10, 2010 to install updates. Shortlyl once the computer is restarted, I got the blue screen of death.  with the details of error like:

    Stop 0 x 000000050 (0 x 000000000000000, 0xFFFFF88001DCAE4, 0xFFFFF8A00B490027, 0 x 00000000000002) do not know if the number of zeros is exactly right in one of those, but it's super frustrating.

    I tried to restart my computer in repair as recommended (get blue screen of death), I tried to reboot normally, loop just restart procedures asking if I want to restart in repair mode.  I tried SafeMode (BSOD), I tried to restart with last working restart (restart loops), I tried to choose the "Computer repair" BSOD I tried a diagnosis and all past.

    Help!

    Thank you.

    So yes actually hear nothing helped me.  Seems that, given that the computer is not stopped correctly and my hard drive was not recognized there starting the cycle upward or give me the BSOD.  Put it in my Ubuntu CD spare which I've had since my last PC hard drive became corrupt and force back across my hard drive.  After doing this, I was able to do a boot repair, who led for the BSOD.  Not sure how that actually fixed, lost about 10 hours of my day.  So I guess I can chalk up to Microsoft and a reminder on why I should buy Mac for now on... an update shouldn't really cause such problems.

    I get that not everyone has the same PC, so it is difficult to tell if an update is bad, but he should not do this and if an update is the cause of a certain segment of consumers who are updating must be taken down for everyone, or at least the users with the configuration that is known to have problems with an update.

    Problem is solved, had to go back to a previous version of good boot where I have not install updates again.  Now, I'm trying to understand who was was bad, so I can leave my computer knows to ignore.

    Nice day.

    Hello

    Do you have a floppy drive?

    If you two options. If you have a floppy drive, you can create boot disks and then start in the recovery console to perform a manual system restore.

    The other option is to attach an external drive and perform a repair of XP installation using a XP install disc.

    Method 1: create the bootable floppy.

    Create bootable diskettes, can be found the article mentioned below:
    http://support.Microsoft.com/kb/310994

    Once you are able to start the computer by using the Setup disk, go to the recovery console and run a manual system restore to restore the computer to an earlier point in time.

    See these articles for help:

  • 2540 HP all-in-one printer print by wifi only works after the router reset every time

    Hi, I recently bought a HP2540 all-in-one printer.

    I was unable to get the printer to work via wifi after trying lots of different things, but after rebooting the router and try again, it worked perfectly.

    However, it seems that whenever I'm away from the computer (or turn printer work) it will not print. However, as soon as I restart the router again it works perfectly. I guess it's something to do with the IP reset maybe, but would be unsure how to proceed?

    Thank you

    Bret

    Hey @BrentBWood,

    Thank you for contacting HP Support of Forums!

    I understand you're having intermittent problems of wireless communication with your HP all-in-one Deskjet 2540. I want to help you resolve this issue today!

    Because the problem seems to be fixed after you powercycle router it certainly seems to be a problem of ports with the router itself. This does not indicate that something is not actually with the router. It simply means that the router is doing its job too well and block the printer intermittently as a threat attempts to access your network.

    For your reference, I'll provide you with the support document HP on wireless connection problems. You already have the reset of the router so don't worry too much about those, but the other steps can help solve this problem for you:

    Printer keeps no connection Wi - Fi

    If these steps don't are still not solved the problem I recommend you talk to your router manufacturer to get them to open the appropriate printer ports.

Their description is a bit vague; of course, it's a kind of liaison between Windows and the graphics controller. Someone on another forum mentioned clear Type part of an independent issue, so in desperation I followed his instructions and found the "secret switch.

    A reboot and the screen comes back. Are there keys, I can try to put light or ideas to test if it's a hardware or software problem?
    Thanks in advance.

    Hello

    It s a very strange problem. But I'll try my best ;)

    I noticed a similar problem on my second book. The display light didn't stop but the blue screen of death (BSOD) appeared and I could not continue my work.

    After a lengthy investigation, I found some useful tips.
    Someone told me that I have to disable HT technology (Hyper-Threading Technology) in the system BIOS settings.

    It's a key!

    As I remember the Satellite Pro A60 also supports this Hyper-Threading Technology.
    You can disable this function in the Toshiba HWSetup tool, in the CPU tab.

    Check it out and maybe it's a key as in my case.

    Dude good luck

  • Black screen HP Elitebook 850 after the mode 'sleep'

    Hello

    I have a HP Elitebook 850, which is about 3 weeks old. It is running Windows 8.1 with most of the HP software, which is available for this model, installed.

    Once the laptop goes into mode 'sleep' may not wake up for some reason any. The screen remains black and seeing everything seems normal. The only thing to do is either ctr + alt + delete to restart or shutdown forced by using the power button.

    Any ideas?

    Best regards

    Has exactly the same problem.  Called HP support.  They said that I needed to downgrade the video driver I was using.

    Specifically they asked me to check the version of the video driver first:

    1. Start screen, type "Device Manager" and then click to open Device Manager.
    2. In Device Manager, expand "graphics cards".  There were two shown:
      Radeon (TM) AMD HD 8500/8700 M M
      Intel(r) HD Graphics Family
    3. They asked me to double click on the graphics card Intel.  The dialog box properties open;
    4. On the tab driver properties dialog box, check the Version of the driver.  Mine was 10.18.10.3379.

    HP support and then asked me to download an older version of the driver, 10.18.10.3316.  Here's how:

    (1) on the laptop in question go to hp.com;

    (2) in the Help menu of hp.com, click Download drivers;

    (3) search by product: Enter 'Elitebook 850 G1' and press Go.

    (4) multiple results will come to the top, select the one that says 'HP EliteBook 850 G1 Base model Notebook PC';

    (5) to select the operating system: "Windows 8.1 (64-bit);

    (6) from the Index to download, select 'drivers - Graphics ';

    (7) tΘlΘcharger "Driver Intel video and control panel (International)" version 10.18.10.3316, November 15, 2013.  It's a big download, 158 MB.

    Once the download is complete, double-click the downloaded file to install it.  If you get a dialog box warning you install an earlier version of the driver that is currently installed, click Yes to continue.

    After you have installed the version 10.18.10.3316 driver, I restarted the laptop.

    To test whether the fix had worked I open a text editor and entered the text without saving it (it was to see if the unsaved document would still exist after that the laptop computer woke up from his sleep).  I then put the laptop to sleep by closing the form.  When I opened it again the light behind the power button has been slowly pulsed on and outside and the screen was black.  Based on the presented power button the laptop out of fashion 'sleep' and return to the lock for recording screen in.  Once connected, I found that the unsaved document was still open for the laptop had obviously just slept and rather than restarted rewoken.

    I hope this helps.
