A gray screen at startup - no solution doesn't work?

• Mac Pro 2008 No. Startup Manager Access/Gray screen on startup

  I'm in a difficult situation and hoping a Ninja Mac can give a helping hand.

  Had a RAM issue (is no longer recognized a pair of memory modules in a 2008 Mac Pro, El Capitan), and among the troubleshooting steps, I did a PRAM reset (press / hold down ALT + CMD + P + R during startup) just to see if it could resolve. Unfortunately, the Mac would not start in front of a gray-white screen with a flashing icon of folder/question mark. Returned never me to get there.

  I had read that resetting the PRAM the disc start, among other things, may need to be reset afterwards, and this seems to be the case. Looked this solution and kept diligently press Option key during startup. This time, no folder icon, instead a sensitive cursor, but nothing else. Gray-white screen only, no boot manager to select the startup disk is suitable.

  I also tried the following...

  1. Starting in the Diagnostic Mode... Gray screen.
  2. Restore/recovery... Gray screen.
  3. Reset the SMC... Gray screen.
  4. Enter Safe Mode... Gray screen.

  OS (and apps) on flash PCI cards. All files are on hard disks in the 4-Bay, as well as a player flash remains connected to a (used as a scratch of PS) free SATA port. So I can't really share, but I wonder if I shoot all readers it would require a search for another source?

  I create an El Capitan USB boot (currently copy with createinstallmedia), but don't expect that it will offer what anyone else that its use is based on access to the Startup Manager at startup..., that I can't do. There are the graphics on the screen (missing folder icon, mobile mouse cursor) so can not imagine a video problem.

  Looking forward to enter here.

  Success!

  I created a USB bootable OS X installer using these instructionsand createinstallmedia. After some messing around with the Terminal syntax USB was ready to go. My concern, however, was that the operating instructions required by selecting the drive of the Startup Manager... which I could not access.

  With the USB stick plugged in I started to turned on the Mac while pressing the key OCCUPIED Palestinian territory and this time, the selection screen pops up showing just the USB key for installation of El Capitan. Got that we open and instead of installing I chose Startup Manager in the installation menu bar, took my normal OS drive and rebooted. Back in business, no problems.

  This put aside, although I understood that reset PRAM would also require reselect startup disk, I don't have a hot clue why did not appear the Boot Manager - or any other useful diagnostic. If someone could throw some light here would be appreciated.

• Satellite L750 - gray screen at startup

  Hi guys,.

  I have Toshiba Satellite L750 slightly less than 2 years. He developed intermittent problems, when starting it arrives with white/grey screen and disappear when the login screen is ready. Sometimes touching the upper left part of the disappears from the screen it. Other wise I have to keep restarting. I have checked the cable connections between screen and motherboard, and they seem good.

  I have also connected my laptop to an external display while it shows the gray screen and the external display. The screen is not cracked or the other.

  Help, please. Thank you

  Googling around you can find a lot of discussion on various forums on similar problems and many different explanations why something like this can happen. On this virtual path, it is not easy to say what may be wrong with your laptop, but it is certainly the unwanted material.

  In my opinion you should either continue to use your laptop until it can be possible and later when the issue gets worse search solution or contact the nearest service Toshiba and ask for help.

  Guarantee is generally of 2 years (depending on the country) but if you opened it on your own guarantee is canceled now.

• Gray screen at startup

  My computer seems to hang because the screen went black. I had to do a hard reboot by using the power button. What I get is a grey screen with a cursor.

  I tried to start in safe mode, or at least, I think that I did by holding down the SHIFT key while starting to but still the gray screen.

  Anything else, otherwise I can try?

  Thank you

  Reboot into recovery now command-r and run disk utility to repair the hard drive. If it still does not start, try to reinstall OS X.

• 10.11.2 gray screen on startup, then...

  .. Press start briefly - black/standby screen, press start up briefly again and we are running.

  Last update downloaded from the on-screen prompt. Does not seem to load correctly, stuck in the gray screen. Shut down and reopened in SafeMode (C) and the message to the 'installation complete' screen and open to my start up screen ok.

  Stop and restart, get the chime and opens it to Apple screen and bar. Bar fills half way, gray screen and sticks. Back to the first sentence!

  I have to start panicking?

  You can start and connect in safe mode, but not otherwise?

• prohibitive gray screen, but the start of the option works

  I have a strange here.

  Early 2011 MBP - OSX 10.10.5.

  Everything was fine with the computer, and then all of a sudden the small wheel of death... computer slows down to a stop and then screen black.

  At startup - gray screen, blinking prohibitory sign several times and then begins to my second hard drive installed (I replaced the optical drive with a 2nd hard drive just in case something like that happens... more... that uses optical discs still!).

  I checked the "Startup disk" options in the preferences, then re-selected my SSD as my default player.

  Restart in safe mode... works as expected on the SSD.  Check disk utility, verify and repair permissions, checked the disk and, say, "could not mount the drive" (perhaps something to do with safe mode?).

  Restart again normally - prohibitive flashes and then after a few seconds, it starts as normal.  I checked the disk utility again, checked and repaired permissions, disk verified and no problem with the disk on THE.

  Stop and try again... lightning prohibitive and then after a few seconds, it starts as normal.  I have reset the SMC and the NVRAM.

  Not sure why I get this prohibitive symbol!

  I have restart holding 'option', all disks appear (SSD, HDD, recovery), so I click on SSD and it opens fine.

  Tips for how to start normally (without the prohibitive sign)?

  Thank you

  A few ideas.

• Only gray screen at startup

  I got the Captivate installed for several months and it worked fine. But now, if I try to start it, I first see the screen start and after the program window is just gray. I can still play it down, but I can only it out via the Task Manager
  I already updated my Flash drive, reinstalled Captivate and used the repair function. None of this has helped.
  
  I would be glad if some of you could help me because I have to finish a few films which are due next week. :-(

  Thank you all for your advice and suggestions!

  None of them could really help my out of my misery, but now, I found a solution (sort of). I used Windows system restore and restored at a checkpoint about a month ago. Captivate seems to work very well now, but I really cannot know exactly what the problem was.

  I will now end my movies before doing anything else...

• Slow startup after installing the SSD because gray screen

  I just installed a Samsung Evo 500 GB SSD in my Macbook Pro 2010. I went to start and it starts very slowly due to a gray screen just sat there for about 30 seconds and then it shows the apple logo and it takes another 15 seconds to load. The gray screen did not appear before installing the SSD but the Apple logo did take longer to load with the HARD drive. I used SuperDuper to clone my my SSD HARD drive and installed the SSD and it starts normally. The only issue was the gray screen. I've heard that I need to go into system preferences and select Startup disk, then my boot drive, but there is no choice. Help, please.

• OSX Update 10.11.3 iMacs causes gray screen of death Mid 2011

  Hello everyone,

  I'm new to the forums of apple, so I don't know exactly if it was to go to the right place. This isn't any question that it's a PUBLIC service announcement.

  Basically, a summary of my post is that OSX update 10.11.3 causes both 27 "& 21.5" mid 2011 iMacs is not start properly. After the update installs and the iMac restarts, the startup sequence seems fine, showing the Apple logo, then the progress bar. However, when you expect your login screen to appear, instead you are greeted with a dark gray screen and movable mouse... and he the system is still a little sensitive. If you press the keys on the keyboard you hear the sound of "bum" as if you had to press a key when you weren't supposed to, and if you press the power button (do not want) the system will switch to standby (and wakes up if you press it again). So this isn't really frozen, it's just nice... it.

  Puzzled, I went to Google, hoping to find someone with a similar problem. I have not found much. I found some people with similar problems (gray screen is a bit more general), but I have found others with 27 "mid 2011 iMacs have this problem (links below :))

  Cannot install the update of El Capitan 10.11.3 (Stuck in gray screen)

  iMac mid 2011, gray screen of death!

  gray screen with the pointer to the login screen

  What I read, some iMacs have been recalled for the failures of graphics card, and that's what some people have responded to in the positions as a possible cause. (This is also what comes mainly from back when you search for "27" iMac screen gray) But this doesn't seem to be the issue here. The above posts are fairly recent and seem to coincide with the update 10.11.3 put in place, and they are the same symptoms that I have experience, but with no working solution.

  Once I have restore my backup time machine last before updating 10.11.3 is installed, the system works perfectly. Unfortunately, if you have not a backup time machine to restore, it seems that reinstall OS x is your only solution (until you reinstall the update)

  I'm not an expert of OSX, but I tried everything under the Sun to try to get the system to boot properly again, like resetting the PRAM & SMC , single-user mode, safe mode, none of this works. The system does not just start.

  I don't know if this has affected everyone with mid 2011 iMacs, but I just thought I'd let people with iMacs 2011 who are having problems with this update that you are not alone, and I hope that someone at apple can be seen. If you have an iMac 2011 that has not been updated to 10.11.3 again, I will not do.

  Thank you

  It is not material, it's software.

  My keyboard came with my Imac aluminum had a problem that I thought was material, but order the update of the post 10.11.2 v works again.

• Black screen on startup Satellite A80

  I get a black screen at startup what is the problem and what is the solution for it? It might have something to do with the cold?

  Hi poly

  Please put more details on the problem, because it s not easy to say what has happened without any detailed information. You hear the operation of the HARD disk or fans?
  Switch you to other devices to display, before this problem occurs?
  Unfortunately it FN + F5 key combination doesn't work if the operating system has started so it could be a malfunction of the equipment. I don t think you can solve this problem by yourself. In this case, the only way is to contact the service.

• black screen on startup of studio15 Dell laptop

  Dell studio1535 laptop... After turning on, the dell logo appears, then it goes to a black screen.  I ran a diagnostic test and I get no error.  He will not start in safe mode, so I can't try the recovery system or Startup Repair because there is no start button.  I have the vista cd, but it doesn't work when I put it.  I called dell, but my warranty has expired.  They tell me there's something I have to do to get the cd to work, but they don't tell me what it was unless I paid 50.00 that I did not immediately.  can someone help me?  Thanks in advance.

  Hello

  Look at the screen as you start at the top and go to settings/settings (BIOS/CMOS) and set the boot on CD/DVD order
  1. don't forget later.

  ====================

  You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
  Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
  on devices and UNINSTALL - REBOOT.

  Another method to try to get to the desktop (try in normal Windows Mode without failure)
  CTRL + ALT + DELETE and on the tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - then
  on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
  by tapping F8 as you start several times.

  First check this thread in case it is simple and if not to come back to this thread.

  Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
  That there is no information on a black screen as it is on a blue screen just adds to the
  Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a
  Google to see the proposed repairs, whom some have worked however these cover a wide
  field efforts.

  Here's a video of one of them.

• 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?
