Gray screen, freezes without end

• (Redirected) USB Flash Drive Boot (BiOS) - black screen/freeze/without end of loading - need help!

  Hello community Dell:

  I have been using your Inspiron desktop for work. Work requires me to a startup USB flash drive every morning to access work files and programs. I just press F12 and select the USB flash drive that brings me then in a workplace Ubuntu after entering my credentials - very easy.

  I recently bought the X 51 office because I wanted the game after work and it was intended to replace the Inspiron.

  X 51 issues (boot BiOS - secure boot off as with the Inspiron):

  UEFI = I get a black screen after the "loading...". ', it freezes the whole system

  Legacy = told me to restart the system and drive and the message repeats little matter what you press

  I tried USB different slots, ending different to access USB - nothing works!

  I tested another theory that would disable the GPU of the X 51, but this proved futile because the problems themselves was replicated. The GPU is the only unique component between two desktop computers. CPU is i3, i5 vs, vs 4g 8g, 1 TB vs. 2 TB, so I do not see these improvements of specification being the culprit. The X 51 has a different unique Alienware BiOS interface.

  The X 51 will be returned to Dell unless someone can some up with a solution - I would be eternally grateful, thank you.

• El Capitan does not start after a freeze and a forced, bonded stop on the gray screen

  Hi all

  I have a MacBook Pro 17 "late 2011, 2.4 Ghz, 16 GB RAM with OS X El Capitan installed, the latest version with all the updates." A year ago, I've had my Toshiba HDD replaced by Samsung SSD 250 GB SATA III 850 EVO and the Toshiba disk has been moved to CD using LMP disk Doubler Bay, at the same time, I had my RAM went from 8 GB to 16 GB of RAM, I have now. The OS X El Capitan is installed on the SSD. In this configuration, everything worked well, with absolutely no problem whatsoever. Sometimes, I ran disk utility to check both of my hard drives and no problem.

  Unfortunately yesterday, strange things started going. First of all, I noticed some unusual glitches when you browse the internet with Safari. I'll try to describe the best I can because they lasted about 2 seconds, so I don't recall. In any case, all of a sudden, as if half right of my screen has shifted in the middle of the screen and it was wrong and image around was all damaged or distorted but legible. He'll be back to normal when I switched between applications or revealed the office displays the windows of all running applications.

  It was similar to this (below) but much larger.

  

  Then, I continued my work as if nothing had happened, when all of a sudden my mouse pointer disappeared and the system froze completely. It was just totally frozen, the time was not moving and the computer did not react somehow to the keys I pressed. Unable to do anything, I had to press and hold the power button to turn off the computer. After starting it again once I hear the ringtone, I see the gray Apple logo and the loading bar. When the loading bar reaches about 40%, a coloured horizontal line appears (see photo below), then it subsides quickly followed by a black screen, which is quickly followed by a blank grey screen with no Apple logo or the bar loading, just a gray screen Uni, where I'm stuck. The computer turns off by itself after about 15-30 minutes if I leave it like that on the gray black screen.

  The coloured horizontal line:

  I can't start in safe mode or recovery mode.

  I CAN only boot single user mode, Apple Hardware Test mode, the boot (by holding the ALT/OPTION key) Manager and verbose mode. Also, I can start on the Internet recovery mode but once the download is complete, it is stuck on the gray screen (gray screen with the Apple logo WITHOUT horizontal line-online quick clear-online stuck on the gray screen black screen)

  After a lot of googling and reading, that's what I've tried so far:

  -' fsck - fy " in single-user mode

  -running Apple Hardware Test and the Apple Hardware Test extended, both are zero problem

  -Reset PRAM and NVRAM, MSC, several times

  -with the help of this guide: https://www.afp548.com/2015/01/14/when-yosemite-has-fallen-and-it-cant-get-up/ in single-user mode: "rm - rf / Volumes/Macintosh\ HD/private/var/db/BootCache * '

  -in single-user mode: empty the trash

  -in single-user mode: "sudo purge"

  
  

  -in a single user mode: 'exit' or 'reboot'

  
  

  
  

  However, during my fight, I could successfully arrives at the login screen, log in and use my MacBook for some time, about a half hour before the same thing happens, the mouse disappears and the system to freeze completely. I remember that both times where I was able to get to the login screen, it was after I had been in single user mode and typed 'Quit' or 'reboot'.

  The above colorful horizontal line also appears in the single-user mode when I type "exit" AND I am UNABLE to get to the login screen later (photo below). It just goes to the gray white screen. Those two times when I was able to connect to exit single-user mode, the horizontal line colored is NOT appear in single-user mode.

  The horizontal line colored when you exit single-user mode:

• Installation of VMWare Workstation 11 freezes with gray screen!

  Hello

  I know this is a very known issue, but difficult to solve, I can't install VMWare Workstation V11 (tried with the old version 8, the same) since as soon as I click Setup, I have a gray screen and installation seems suspended it.

  Tried the same thing with VMWare Player, same result, even with older versions...

  No way to close the gray screen, unless you kill the process.

  My case is laptop Thinkpad T510, native W7 64-bit, processor Intel i5, 4 GB ram, Java utility installed and 100% updated, Nvidia GPU, nothing strange.

  Microsoft Security essential only running, no other AV or firewall...

  I tried to save two files reading autour on this community, but this does not solve the problem.

  I see not what is a well known problem and it is absurd does not have a way to solve it on VMWare...

  Any help is very appreciated!

• Only get a gray screen after upgrade of El Capitan. What can I do?

  I tried to install an upgrade, but only now have a gray screen.  The installation seems to have stopped half way through.

  Please take each of these steps that you have not already tried it. Some of them are not applicable to your model or your situation. Stop when the problem is resolved.

  To restart a computer is not responding, press and hold the power button for a few seconds until the unit turns off, then release, wait a few seconds and press again briefly.

  Step 1

  The first step to respond to a startup failure is to secure data. If you want to keep the contents of the boot drive and you have not already at least a current backup, you should try to back up now, before we do anything else. It may or may not be possible. If you don't care the data changed since the last backup, you can skip this step.

  There are several ways to back up a Mac that is unable to boot. You need an external hard drive to store backup data.

  a. starting the partition recovery or an hour Local Machine backup volume (button option key at startup). When the OS X Utilities appears, launch disk utility and follow the instructions in this article to support. You'll be 'restoration' the boot on the backup volume volume.

  (b) If step 1 fails due to disk errors, and no other Mac is available, then you may be able to save some of your files by copying them in the Finder. If you already have an external hard drive with OS X installed, the start of it. Otherwise, if you have access to the Internet, follow the instructions on this page to prepare the external hard drive and install OS X on it. You will use the installation program of recovery, rather than download it from the App Store.

  c. If you have access to a Mac, and it work and have both the non-working Mac FireWire ports or stroke, start the Mac non-working in target disk mode. Work Mac to copy the data to another drive. This technique will not work with USB, Ethernet, Wi - Fi or Bluetooth.

  d. If the internal drive of the non-working Mac is replaceable by the user, remove it and climb into a docking station that is pregnant or an external drive. Use another Mac to copy the data.

  Step 2

  If you have booted from an external drive, make sure that the internal boot volume is selected in the pane of the system preferences Startup disk.

  Start in safe mode. Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. If you do not see the words "Safe Boot" in the start screen, you did not start in safe mode. Ask for additional instructions.

  Safe mode is much slower to boot and run as normal, and some things don't work at all, including the networks without wire on some Macs.

  The login screen is displayed even if you normally connect automatically. You must know the password for the connection to connect. If you have forgotten the password, you will have to reset it before you begin.

  If the startup progress bar gets stuck for more than a few minutes, or the system stops automatically when the progress bar appears, the boot volume is corrupted and the player is probably defective. In this case, go to step 9. If you have another problem with the player, replace it immediately.

  If you can start and log in in safe mode, empty the trash and then open the window of info on the boot volume ("Macintosh HD", unless you have given it a different name.) Make sure you have at least 9 GB of space available, as shown in the window. If you do not, copy as many files as necessary on another volume (not another folder on the same volume) and delete the originals. Deletion is not complete until you empty the trash again. This, until the space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)

  If the boot process hangs again, the problem is probably caused by third-party software you have installed. Ask for additional instructions.

  Step 3

  If the startup process stops at a gray screen together with a mobile cursor, then the logon dialog box may be active but not visible because of a bug. You may be able to connect by using the arrow keys or the cursor to select the password field and type your password as usual.

  Step 4

  Case of failure of step 3, the boot volume can be complete. If you saw previously implemented guard space drive is low, it is certainly the case. You might be able to start in safe mode , even if you cannot boot normally. Otherwise, boot from an external hard drive, or well technology for step 1b, 1 c or 1 d allows to mount the internal drive and delete some files. According to the documentation from Apple, you need at least 9 GB of free space on the boot (as shown in the Infolog) for normal operation volume.

  Step 5

  If a Mac desktop (without the built-in keyboard) crashes on a gray screen together with a mobile cursor, the keyboard may not be recognized. Hold down the button on the side of a wireless Apple keyboard to make it discoverable. If need be, replace or recharge the batteries. If you use a USB keyboard connected to a hub, connect it to a built-in port.

  Step 6

  Sometimes, a startup failure can be solved by resetting the NVRAM.

  Step 7

  If there is an integrated optical drive, a disk may be stuck in there. Follow these instructions to remove it.

  Step 8

  Press and hold the power button until the unit turns off. Disconnect all devices wired except those needed to start and remove all aftermarket expansion cards. Use another keyboard and/or mouse, if these devices are wired. If you can start now, one of the devices that you disconnected, or a combination of both, the origin of the problem. Discover that it is a process of elimination.

  Step 9

  Launch the utility disk in recovery mode (see step 1). Select the boot volume, and then run the repair disk. If problems are found, repeat until that clear. If disk utility reports that the volume is not repairable, the drive is defective and must be replaced. You can choose to tolerate such malfunction in the reader's life. In this case, delete the volume and restore it from a backup. If the same thing happens again, replace the drive immediately.

  It is one of the rare situations where you must also run repair permissions, ignoring the erroneous warnings, that it can produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.

  Step 10

  If the boot device is an aftermarket SSD, it may have an update and/or a forced "garbage collection". Instructions how to do this with a Crucial SSD of brand have been posted here. Some of these instructions may apply to other brands of SSDS, but you should check with the technical support of the provider.

  Step 11

  Reinstall the OS. If the Mac has upgraded an earlier version of Mac OS X, you need the Apple ID and password used to upgrade.

  Step 12

  Do as in step 11, but this time clear the disk utility boot volume before installing. The system should automatically restart in The Migration Wizard. Follow the prompts to transfer data from one Time Machine or another backup.

  Step 13

  This step applies only to models that have a battery logic-board ("PRAM"): all of the Mac Pro, MacBook with a removable main battery and a few others (models not updated). A flat battery logic-board may cause a boot failure. In general the failure will be preceded by the loss of the system and boot disk clock settings. Refer to the user manual for replacement instructions. You may need to take the machine to a provider of services to have to replace the battery.

  Step 14

  If you get this far, you probably deal a hardware failure. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

• iMac mid 2011, gray screen of death!

  Hi all! (Sorry my spelling Im Danish)

  I have an iMac mid 2011, 2 TB HD, 16 GB of Ram and a video card AMD Radeon HD 6970 M 2 GB. My problem is the gray screen of death! After starting, I see the Apple logo and progress bar. When the progress bar stops, the screen goes gray and stops loading. I tried the following.

  1. Reset the PRAM og MSC
  2. Boot in single-user mode and fsck - fy
  3. Internet starts form Apple Hardware Test - no error at all!
  4. I tried starting in safe mode, I see the logo and progress bar, but it ends with the grey screen of death
  5. Tried to start with only the original RAM
  6. Tried to start without anny perihperal eqiptment (keyboard, mouse, ect.)
  7. Tried to start mode of recovery and a USB stick and an installation DVD, I see the logo and progress bar, but it ends with the grey screen of death
  8. Tried to do an internet restotre of Apple, I see the logo and progress bar, but it ends with the grey screen of death
  9. Began the iMac in target disk mode and got access to another iMac. A ran the disc utilities and first aid, always on the go!
  10. Started the iMac in target disk mode and made a full HARD disk cloth! Make new partitions tree and a clean install of the other iMac. And after that, the iMac problem still won't start!
  11. I can boot from HARD drive of the problem (in the mode of target diks) iMac via another iMac, so I guess the drive in the iMac problem is in working condition
  12. I also assume that the screen (video card) on the iMacis problem at work order due to the fact, that I see the Apple Start logo and progressbar. As well as the Apple Hardware Test run via the Internet (no video error)

• Blank gray screen on wake?

  So I am using this Mac mini (late 2014, 2.6 GHz Core i5, 8 GB memory, 1 TB HDD, OS X El Capitan 10.11.6) for almost a year now and I'm having a serious problem with waking up from his sleep recently. If I let him sleep long enough, I get a gray screen on wake. No progress bar or the other and it can go up to a half hour without doing anything. I turned off the Hibernate using pmset just in case, and the problem is still happening. Happen 3 - 4 times so far.

  Moreover, some of the keys on the gray screen gives an error sound system. I don't know if this means that it is a problem with OS X or not, but I'll bet it is, as I ran Apple Diagnostics and it showed that there are no are no hardware problem. I'm really confused now. Has anyone else experienced this?

  I can watch 4OD and demand by using Internet Explorer 5, but I get all the annoying ads. I used to use iGoogle instead, who got rid of all the ads, but recently it has stopped working, and now there is just a gray screen where the video should be.

• Satellite M70 164 - screen freezes and goes black, overheating

  Hello world! :)

  Recently my Satellite m70-164 started to freeze after only a few minutes of work. The picture on the screen freezes, and a few seconds later, it becomes completely black.
  The computer doesn't even have time to warm up, and it's not stop... It's just the screen that freezes and becomes so black. I have to reset the computer by pressing the power button. (I write from another computer).

  I noticed that working time reduced whenever I have reset the computer and after some time it freezes even though I am in the BIOS settings, so I don't think it's an OS problem.
  Even if the computer does not have time to warm up, this suggests it might be a heat problem.
  So I tried pointing a fan this is low (a big, like the ones we use in the summer), and it works without problem!

  With the fan facing these, I reinstalled Windows - so no Virus.
  Laptop fan * not * continue to operate as it is overheating.
  The fan runs and it is not clogged as I've cleaned.

  So if anyone has the same problem, or ideas, please respond!
  (And sorry for my English)
  Thanks in advance! : D

  Hey Buddy,

  I agree with you. In this case, even in the BIOS, that it has nothing to do with Windows or a Virus. In this case, it seems to be a hardware malfunction

  But before contacting an authorized service provider to diagnose what part is the cause, clean your laptop using a jet of compressed air. This should be done from time to time (every 4 months) and, therefore, it of not necessary to disassemble the laptop.

• Toshiba U10 Docking Station causing screen freeze

  After running my monitor external docking of th #rough the U10 my screen will freeze periodically. The only way to UN - freeze is to detach the PC and then re-dock.

  I use a 32-bit laptop to Windows 7 with 3 GB of RAM. All drivers and patches are up to date and I have to update the U10 driver to the latest version, all this without any successful resolution.

  Any help would be appreciated as it happens at least 4 times a day and is very annoying and embarrassing.

  Thank you

  Hello

  I think that it of difficult to say what could be the problem exactly.
  You are able to reproduce this issue? I mean you said that the screen freezes periodically does happen a certain application running?

  As far as I know the European Toshiba driver page provides the utility Dynadock v2.4.0.13 for Win 7 32 bit and 64 bit.
  The v 2.1.4.4 Setup CD is also available for download

  Maybe you need to reinstall this even if you said, that you use the latest version of the software
  I would also recommend test this Dynadock in relation to another PC
  Maybe the laptop preinstalled software causes this problem.

• Satellite M70-169: screen freezes and meshes + mouse freezes

  Hello
  Hope you can help. So far, I'm impressed by my toshiba satellite m70-169.

  He has recently developed an intermittent fault: when the tilt of the screen the effect of light mesh on it and the screen freezes. The mouse also hangs at this point.

  If I tilt the screen one way or the other I can get it to work properly. A slighy inclination of the screen can cause the screen to freeze again. The problem is getting worse, however.

  The machine has never been dropped or struck, but was taken by one of the screen when it is open.

  I disassembled the strainer and push gently on various points and cables but nothing in this area suggests a loose connection or a weak point. So I believe the problem is in the essence. I tried to open this up but it fails because I didn't force anything.

  Question 1: any suggestions on the problem and possible solutions?
  Question 2: advice like how to open the main part, so I can check any loose cables, connectors or broken bones?
  Question 3: patterns for disassembly?

  Even once - I hope you can help - thanks in advance...

  Hi John

  The above user is right. It s too risky to disassemble the laptop without having any experience with laptops.
  It is why I always recommend taking to a technician.

  But if you want, you can have a look here:

  It s a site on satellite M55 and withdrawal screen.
  But once again; You can do everything BUT only at your own risk! ;)

• Play NFS on the Satellite X 200 screen freezes shortly every 2-3 seconds

  I recently bought a Satellite X 200 with 2 x GeForce 8600 M GT in SLI.
  Due to the power of 2 graphics cards, I thought about playing games would be no problem.
  But it's not...

  I just bought Need For Speed - Pro Street and installed on my computer. I can't play the game, without the screen freezes shortly every 2-3 seconds.
  It seems that there is not enough power visually, but with 2 x 8600M GT in SLI? Will not take the game run smooth without delay?
  I have all the settings at low temperature and/or offshore, trying to see if that would solve the problem - but no.

  The menus and the intro works very well, but when driving cars in the game, it starts to lag.
  I've updated to latest drivers, but which did not help either.
  My OS is Windows Vista Home Premium, and my memory is 2 GB.

  A problem like this?

  Hmm I think that it of because of Vista.
  I read a lot of articles on issues such games on Vista OS.

  I found some Vista patches and patches but I really not 100% sure if this QFE have reason.
