Blank Screen or Freeze???

Bought new mac late last year, it has been OK, until few weeks ago. My Mac went blank itself for no reason but not fully shut down as I can see full grey on screen background but nothing on it. I could see that the screen is still on but no mouse pointer on screen nor the keyboard won't functionally at all. I have to press and hold off button for while to turn it off then turn it back on. It happens few times now. Does anyone know how to solve this problem.

I was having the blank screen on wake up problem and had changed my power management settings, go ahead and check out http://www.unofficialmac.com/post/27756671.

Thanks in advance ;(

Hi,
First check your CPU-cooler, if it's mounted wrong the board will shutdown to prevent damage to the CPU....
Check if the JBAT jumper is set to position 1-2 to safe the data....
Please read the trouble shooting guide entirely....it might just solve your problem...

Try the repair method from this Apple Doc: FSCK - File System Check
To start up in single-user mode
1. Restart the computer.
2. Immediately after the startup sound, press and hold both the Command (⌘) and "s" keys on your keyboard. The computer will display a series of text messages, at which time you may release these keys.   When the computer has started up, it will display a command line prompt (#). The computer is now in single-user mode.
How to Run the File System Check from the Command Line Once you have reached a command line, follow these steps to use fsck:
1. At the prompt, type: fsck -fy (NOTE: there is a space between the k and the “-”) The fsck utility will go through five "phases" and then return information about the disk's utilization and fragmentation. Once the check is finished, if no issue is found, you should see "** The volume appears to be OK."   If fsck alters, repairs, or fixes anything, it will display the message:
****** FILE SYSTEM WAS MODIFIED *****
2 - IMPORTANT: If this message appears, repeat the "fsck -fy" command until this message no longer appears. It is not unusual for your computer to require several "passes" of fsck, because first-pass repairs may uncover additional errors. Run it until you get two consecutive times with an "OK" result.
3. When fsck reports that no problems were found, type: reboot
4. Press Return.
If you can get into Single User Mode and run the file system check it might be able to fix the damage to the system that appears to have occurred. Worth a try.

IMac goes blank screen and freezes

Hi,
I got 24" iMac running OS X 10.5 and Win 7. Last night I was running windows playing some game when screen gone totaly black for unknown reason and iMac froze.
After that booting to OSX it caused grey screen just after a couple of seconds when the desktop has showed. Booting from recovery CD causes the same at the point when you see "Loading Apple" thingie.
I did extended apple hardware test and it showed nothing.
They only way for me to get online and post this message is getting Win7 into a safe mode or VGA mode without NVIDIA driver loaded. Btw when booting win7 normaly it goes black screen after the desktop loaded.
My warranty period has expired month ago. And last time contacting support about the hard drive issue was a real trouble. Im in Ukraine, Odessa. And this guys are in Kyiv.
So what should I do?

update:
OS X seems to be working in safe mode and, I got crash report after booting in normal

I had this same thing happen to me. I was using my brand new iphone 5 (texting and listening to music through the speakers) when it flashed the apple logo, stopped my music and brought me to the lock screen.

What to do if it freezes with a blank screen

Tried to restart the mac pressing CMD+Opt+On/Off then pressing CMD+R+On/Off with the restart sound going off. However, it still freezes with a blank screen. All control buttons such as brightness and volume do not work at all. After waiting for few seconds, it ask me to press Return key if i wanted to put english as my language which i did and still with a blank screen. A few seconds later, the edges around the keyboard became hot. Then i tried to restart it the same process a few times, still the same results. This happened right after i login into my account.

Blank screen of death after iphoto 11 freeze

Dear iphoto users
Last night after a deep freeze during iphoto 11 presentation my Imac is stuck in the blank screen during reboot, no way to recover it (all devices disconnected, zapped PRAM, reset PMU and so on).
Disk seems OK after a check in Single user mode, I can even access disk content from LAN. I cannot even start from the DVD: it make some noise but the device is not recognize (booting with option key only HD is recognized as bootable device).
Any advice? TIA

HELP with Satellite Series - P305-S8837; displaying blank screen with cursor

Help! I have a the P305-S8837 laptop in the Toshiba Satellite Series. I have had the laptop for several months now and it's been working fine until now. I was using it this morning (on the internet) and it started freezing up and so I hit Crtl + Alt + delete and selected the option to restart. It restarted and asked which mode I wanted to start it up in (safe mode, safe mode w/networking, etc.) and I selected the normal option. It started out fine - little windows logo came on with the sound and then went into the Welcome Windows Home Vista premium page (that's like bluish greenish) and then afterwards the screen just goes blank with the exception of the mouse cursor. I let it sit for about an hour and there was no change. I have tried pressing the Crtl + Alt + delete and that has had NO affect. So i manually turned it off and then back on using the power button and tried starting it up in Safe mode w/networking and then just safe mode - both are able to get to the welcome screen but after that it's just a blank screen with cursor and it says safe mode and stuff on the border. Crtl + Alt + delete does not work in the safe mode w/networking but in just the regular safe mode it will go to that same screen that is the welcome and ask if I want to lock the computer, change users, start task manager or restart / shut down. I have selected the restart option and nothing happens and then the Crtl + Alt + delete option no longer works. I have tried manually starting the laptop with the battery unattached and just using the AC Adapter and that has had no impact. I have tried just using the laptop's battery only with no AC Adapter and that has had no impact.
As you can see, I am in desperate need of some assistance! Please tell me what to do!
Thanks

Turn the computer on and immediately press and hold the F8 key.
On the Advanced Boot Options menu, choose Repair Your Computer.
When you reach the System Recovery Options menu, choose Startup Repair.
If that doesn't do the trick, go back to the System Recovery Options menu and do a System Restore.
If that doesn't fix things either, go back to the System Recovery Options menu, choose Command Prompt, and follow the directions here

Blank Screen and flashing cursor on new build-P67A GD65 (B3). Help needed.

As per the title, a computer was built for me with the following specs:
CPU: Intel Core i5 2500k
Cpu Cooler: Arctic Freezer xtreme Rev 2.0,
Motherboard: MSI P67A – GD65 (B3)
PSU: Super-Flower Amazon 550W
RAM: 4GB G.Skill RipJaws-X, DDR3, 1600
HDD: 1TB Samsung Spinpoint F3 7200rpm
Graphics Card: Sapphire Radeon HD 5850 Xtreme - 1 GB GDDR5
Disc Drive: Samsung SH-223C DVD+RW
Case: Cooler Master 690 II LITE Midi-Tower
OS: Windows 7 Ultimate
Everything went ok with the build and installation of the OS. Computer was booting ok. When I took the computer home that evening, powered it on and a blank screen with a flashing cursor on top left hand corner appeared. Tried several times but failed to boot up properly. Just to note that I can enter into the BIOS and it recognizes HDD, processor, Disk Drive and RAM. What I have done so far (of course with advice from computer experts as compared to me) are the following:
1. I removed all the parts except cpu and cooler then put them back. When I restarted a message appeared that win7 need to do a repair. It went thro the process and then it stated it can’t do repair. Did this twice. When I restarted the third time, a blank screen with the blinking cursor appeared again.
2. Cleared the BIOS using the button on the outside of the motherboard and also once using the jumpers inside the motherboard. After doing this, I pressed on the “”ON” button several times (with no power on to the computer) to dissipate any current that was left there.
3. Interchanged the RAM on different slots. Also tried using only 1 stick of Ram at a time.
4. Checked the HDD on another machine and it was ok. Formatted the HDD on the other machine, plugged onto new machine and tried to install OS again but no joy.
At this point, I’m now stuck after almost a month when the machine was built. Would it be the motherboard? RAM? etc. Just wondering if I should RMA the motherboard since it is just over a month when it was delivered.
A point to note, there is a message that comes up when it is booting stating no HDD is detected. I googled this but found out it was to do with a marvel adapter that needs to be disabled or something like that. However, it was mentioned that this wasn’t going to affect the performance of the pc as the BIOS can detect all the components.
I also noticed that when I switch on the pc, there is a small pause before it kicks on then there is a long beep followed by 2 small beeps. I presume this is normal.
Any help on this will be highly appreciated?

Disable EuP 2013 & that should take care of the pause. The beeps are normal at startup. Only time I have observed a blank screen & blinking cursor is if the system wasn't getting enough juice to initialize, or their was insufficient power in an OC attempt. What kind of +12V amps does that PSU you have provide?

I have a 3rd generation iPad running iOS7.0.2, and since updating to iOS7, it will not mirror to an AppleTV. The devices will connect, but the video monitors show only a blank screen. The AppleTV's work fine with various other iOS & OSX devices. Ideas?

I have three AppleTV's where I work. I have two at home. I have an iPhone 4S running iOS7.0.2 which mirrors smoothly via AirPlay. I have a 2011 MacBook Pro and a 2011 iMac, both running Mountain Lion, both of which mirror smoothly through AirPlay. I have a 3rd generation iPad running iOS7.0.2, and since updating to iOS7, it will not mirror. The iPad will connect to the AppleTV, but the TV's and projectors only show a black screen when connected: the iPad screen looks as it should, except that the transitions become jumpy when connected via AirPlay. This is true on both networks: at home and at work. Another gentleman using the network where I work has the most recent iPad, also running iOS7.0.2, and he is having the same problem. I have tried to "Reset All Settings." I have tried to "Restore." Does anyone have any suggestions? Has anyone else experience difficulty mirroring the iPad through AirPlay since the release of iOS7.0.2?

No problems exists with the router (on either network described above) or the multiple AppleTV's which are able to mirror multiple other OSX & iOS devices seamlessly. The problem is strictly with the iPad and iOS7.
The following information was helpful:

Re: AirPlay with AirServer connectivity problem
Oct 14, 2013 9:43 AM (in response to ceb2652)
This is an iOS 7 AirPlay mirroring bug...
To make matters worse, the iPad automatically drops its mirroring session 45 seconds after it auto-locks.
3-4 mirroring sessions is all it takes for the iPad mirroring to freeze up.
After this happens, mirroring to an Apple TV only projects a blank screen.
Once the mirroring is hung, the only way to fix it is to restart the iPad.
Apple please fix this iOS 7 issue!

No startup: blank screen, power light on, fans normal speed

iMac G5 2.0GHz, 2GB RAM, 160GB HD, OSX 10.5, 17". Bought in October of 2005. Two matched Samsung 1GB RAM chips installed quite some time ago with no problems.
While it isn't the iSight model, my iMac has done the blank screen with fast spinning fan thing a few times, but it always recovers after I turn it off. Here's what happened:
iTunes is playing, I pause it using the Play/Pause button on the new wireless aluminum keyboard, it sits for a while and the screensaver comes on. I press the Play/Pause button on the keyboard again, the screensaver freezes and the fans spin up to maximum speed. I hold the power button down, it shuts off, I turn it on again and get nothing. It now powers up to a blank screen, fans at normal speed, the power light stays on, and the CD drive never makes its little startup noise. Holding the power button down does nothing, I have to pull the power cable out to turn it off. The only thing it has done differently since this happened is one time the power light didn't come on, otherwise no change. I also tried all of the different key combinations on startup (using the USB keyboard) and get no response, so no target disc or safe modes. Also, the CD drive won't accept any discs, so I can't start from the system discs.
I don't want to pay for any expensive or major repair work since I was going to get a new iMac this Fall anyway. If anybody has any clever do-it-yourself tricks I'm wide open to them. Otherwise it looks like I'll just get a hard drive enclosure kit and get all of my stuff off that way.
Help please!

First, you may still be eligible for one of Apple's Repair extension programs also, try resetting the SMU.
Let us know what happens,

13 inch mid 09 MBP will not boot in safe mode or os disc. originally kernal panic but now blank screen. is this logic board? no liquid damage.

I upgraded the ram and hdd a while back(RAM first with no issues, then hdd around 2 months later). The computer started freezing a few days after the hdd upgrade.
I reformatted the hdd and it worked fine for a few weeks then same freezing issue. Instead of wiping the drive again I repaired the disc and this had it fixed for about a month. I was booting in safe mode for a few days with no issue and went about uninstalling 3rd party apps. Then the Kernal panic issue started, When I inserted the OS cd the screen went blank and has not come back on after repeated boots.
Can we put this down to logic board and if so can it be repaired rather than replaced?
Thanks

thanks for the reply,
just reinstalled the factory RAM and HDD. Same issue of blank screen. At the moment i have no way of connecting to external monitor.
The OS cd is still in drive and i can hear the drive spinning for a few seconds at the start but it stops after about 20 seconds.

Blank Screen or Freeze???
