Hardware :: Computer Switches Itself Off - Getting Gray Screen
Feb 19, 2010
I have a 20" iMac G5 1.8 GHz which has been pretty reliable since new. A few weeks ago I fitted a new Hard-drive (Western Digital Caviar Black 1TB), other than that the computer is bog standard. For the last few days when I start up, the computer switches itself off straight away and I have to press start again. Sometimes it gets as far as the grey screen and sometimes it gets to a complete desktop screen before this happens. This may happen 2 or 3 times and then the computer works fine all day, I can even restart with no problems once it is running fine. As it stands I can live with the problem but I worry that it may get worse. Anyone know what this might be? Could it be related to the new hard-drive? Could it even be related to the cold weather?

My computer has started randomly popping up a grey screen which tells me to restart. It keeps happening and obviously something is wrong. Not sure if it is a hardware failure but something's broke! Anyone know what the deal is? Here is my latest panic log:

While working on the computer, sometimes the screen will turn gray (from top to bottom) and a message will appear saying the computer must be restarted.So far the local Apple store has not been able to find the problem. The last solution the store tried was to replace the Airport Card, but that didn't work. Computer was purchased in December 2011.
Info:iMac (27-inch Mid 2011), Mac OS X (10.7.2)

Allright so my girlfriend accidentally spilled a drink on her macbook the other day. We thought we had cleaned it off and everything was fine. We were mistaken. During normal usage the computer crashed so we restarted it and are now greeted upon startup with a gray screen and a gray application folder with a question mark on it flashing repeatedly. What is the course of action guys? I'm not computer whiz and I'm wondering if we can fix this ourselves without having to take it in for repair. And FYI she does not have apple care

my dual 2.3 ghz G5 power mac with 3.5 gig memory running 10.4.11 started crashing (grey screen "you must restart your computer...) and soon stopped booting. suspecting the hard drive as it had been noisy for some time I ran "repair disk" in disk utility from my mac book (connected by firewire, G5 booted as target) and it booted again but soon crashed again and after a couple more crashes it would not boot and attempts to repair failed. I installed a brand new hard drive, installed osx 10.5 and updated it to 10.5.8 and it seemed to install and boot fine but while trying to burn a .dmg dvd with toast (10.0.5) I got the grey screen anain and repeated attempts to burn a disc with the same .dmg resulted in a crash every time. it has also crashed while downloading, playing back itunes hd video, and using an "eye tv hybrid" tv tuner as a dvr. below is the most recent crash log - note that most of them have referenced cpu 0 although the most recent it's cpu 1 -THANX & PLEASE HELPInterval Since Last Panic Report: 0 sec Panics Since Last Report: Anonymous 4A58CF1E-844-409F-8BF3-65A3A3CD2E79.......

I'm noticing some weird behavior in my Mac Pro first gen.
Basically, when I start it up, the displays just stays black for some time, until the Desktop loads up and the computer is functional, but never displays the gray screen with the Apple logo. This just happened all of a sudden and stayed like this.
I know is not a big deal now, but I'd like to sell it in the near future and this could be problematic for that.

I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.
I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

I got a 3 year old white macbook. I was surfing the net when suddenly it turned off. On restart, I got the grey screen for a while, the a picture of a file with a question mark in it, waited for ten minutes, still the file. I have done the following:
1.- Reset the PRAM: I use the combination of keys, and it reboots, but on rebboting it goes back to the picture of the file.
2.- Use the option key on startup: I get a grey screen with the curso on it, which I can move with my mouse, but no buttons to click or nothing.
3.- Use the X key: as if doing nothing
4.- Resseting the SMC: as if doing nothing

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.
All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.

I recently upgraded to 10.6.5 from 10.5.8. Ever since then I have had a problem with spaces. The problem is as follows:
When switching Spaces, there is the onscreen graphic along the bottom, telling you which space you just switched to. However, sometimes when switching spaces on SL 10.6.5, the graphic will stay there and wont disappear as it should. When it just stays there, the entire keyboard stops working because Mac OS X still thinks I am performing the Spaces switch. A logout is required.
I am running 10.6.5 with all updates applied.
I searched for this problem both on MR & on google, and although it seems that I am not the only one with the problem, I can find neither a cause, nor a solution.

Unfortunately I bumped the switch on the power strip that my Mac Mini (1.42ghz G4, OS X 10.3) is plugged into while it was running. Now it won't boot up. All I get is the gray screen with the gray apple logo and the spinning wheel but no OSX.

I have Spaces enabled to provide 4 virtual screens. My problem is that I am in a Pages document, and I press Command-F to do a search. Spaces switches to a different virtual screen because for some reason it thinks the Find window belongs in another screen. The workaround is to move the document into the screen where the Find dialog opens. I suppose the cause is because Pages was originally opened in another screen, and moved, but the Find window thinks it belongs in the original window. Again, to me this is not a feature, but a bug.

My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.4), 8GB RAM

upon startup i see a gray screen, the apple logo, and spinning gears. Then the apple logo turns into a circle with a line through it and stays that way forever. I call apple support. They got me to run disk utility by booting from install disk. Then running repair disk and repair permissions. Then boot into safe mode and computer works fine...for a few restarts then does the same thing.

Something strange happened to my Mac, I use a USB modem by Orange il. Mac recognized it with no problem and installed the installation package. After installation when Mac recognized the modem again a gray screen appeared and asked to do Hard Reset. I'm using Snow Leopard 10.6.2 and I had no such problems with it. It happened to me once when I had version 10.5 and changed Drivers for usb to use Dfu. I checked the computer, and to be sure I downloaded the new drivers and reinstall it and it still happens when I insert the modem. As soon as I uninstall the modem I can insert it without a problem until I install the drivers and then this Crash happens again.

I have an 2008 iMac that displays a gray screen. I cannot get rid of it. I have done a forced shut down but it wakes up when a key is depressed. I have turned off the power. It will chime but a gray screen, not a spinning wheel or anything else. I was told it might be VMWare Fusion at fault so I uninstalled the program a month or so ago. It was fine until a few days ago. Has the display panel died? If so, is this a dyi or should I pay $$$ to repair it.
Info:
iMac, Mac OS X (10.6.1)

I posted this in the emac forum, but since it concerns the OS....thought I'd also post here. have an older emac 700 that used to work, but now when I try to boot ...after the apple screen with spinning wheel I get the gray screen of death. I have tried lots of things, including reinstalling OS from a retail purchased 10.4 dvd. THe OS install *looks* like it is working until it goes to reboot at the end, & then hangs again. I have also tried booting off a firewire drive, again, hangs. I know that there are boot cmd-v or -s options that give readouts of what's happening, but I don't know how to pause the process & whatever messages of relevance may be present near the end disappear quickly when the screen turns gray. In the process I have also zapped the pram/nvram.....& have reset the pmu button. I'm at the end of my rope, as I'm all out of things to try. As for what I was doing when the whole thing went south on me.. I was playing with a newer Belkin usb wireless adapter & trying to find the right driver. I downloaded the Zydas zd1211 driver set, but inadvertently unpacked the 10.3 version instead of the 10.4 (which is what this emac has). It went into auto reboot & that was that.....gray screen of death. Coincidental? I dunno. I just include the detail.

I have an Intel Mac Mini that I use with a Viewsonic DVI LCD. My problem is that the gray boot screen doesn't ever appear. The computer starts up, but the display doesn't come on until I unplug the monitor and plug it back into the mini, then it comes on and I see the login window. Anyone have any tips for me? I've tried the cmd-opt-p-r, and resetting it via plugging in the power while holding the power button, but to no avail.

I am running Snowleopard on a 24" white imac bought in 2007. My system has been somewhat temperamental for a few weeks, crashing out on me when waking up and generating random artifacts onscreen during use. I noticed also that the hardrive recently renamed itself as "EMI Boot" when booting using the option key (although it worked fine). Now, when booting, the apple logo appears, followed by the spinning wheel and a blank gray screen. Then nothing. The same thing happens when I try to boot using a mirrored backup drive or a separate bootable drive with a different version of OSX. The imac drive will, however, launch using a MBP in terminal mode without problem. I have run Diskwarrior and fsck on the drive. No difference. I've tested the RAM using memtest in single user mode. RAM seems OK. I dont have the original installation disks, so cannot run the diagnostics.
