Macbook Sudden Restart

So the problem started this week and has happened twice so far. I'll be doing something on my macbook. It happened once while surfing the web with google chrome. Then it happened again while I was DJing using Traktor Scratch Pro. I'll be minding my own business. Then I will hear a beep, a grey sheet descends on the screen, i can see everything behind it, its just been tinged grey. Then a warning pops u[ that tells me to restart my macbook by holding down the power button or pressing the restart button. The warning is repeated in various languages. The screen is frozen and I have no choice but to comply. The warning is not a window, its just a warning, like the blue screen of death, it just appears. I comply with the warning and the computer restarts. When I restart, I am greeted with a mac OSX quit unexpectedly, send report window on my desktop. I send the report and now I'm here.
I've never had this happen before and now it's happened twice in like 3 days. Some cause for concern.
Any ideas on what is going on? I'm just about to go clone my HD just in case.

What you are seeing is called a kernel panic. KPs are most often traceable to RAM problems or incompatible or outdated software. Read this article and follow its suggestions *in order:*

Take the computer in for service. You have a failing GPU.
MacBook Pro (15-inch, Mid 2010)- Intermittent black screen or loss of video
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's the portion of the kernel panic log that points to the faulty NVIDIA card:

Boot in safe mode

My macbook suddenly is running very slow

Help! my macbook suddenly became painfully slow, it freezes every 30 seconds. I took it to the Apple store, they said the hard drive was fine, they restored it and updated the operating system.
At first it was a little better, but it came as slow as it was before.
I hope you can help me! im desperate

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

The keyboard and trackpad to my 2008 MacBook suddenly stopped working, what's wrong with it/ what should I do to fix it?

The keyboard and trackpad to my 2008 MacBook suddenly stopped working. I've restarted the computer several times and no help. I had some keyboard maintenance done a few months ago at a repair shop so I don't know if that has anything to do with it. What should I do?

First thing I would try would be to remove the battery from your MacBook, connect the computer to it's power adapter and start up, then see if the keyboard and trackpad work normally. Some older batteries have been known to expand and interfere with keyboard and trackpad. If this works, replace the battery.
Best of luck.

My MacBook suddenly turned off. And won't turn on

My MacBook suddenly turned off. There was a click sound and then nothing. I have tried to restart it but nothing happens. No sound no lights. It is plugged in and the power cord shows green. I have not damaged it in any way.....

Here is what to do;
1. Unplug everything from your computer.
2. Take off the bottom of your MacBook / Pro / Air. (There are usually 3 screws that are longer than the rest near the vent, remember where they go.)
3. Carefully unplug the battery from the logic board.
4. Wait 10 seconds.
5. Plug the battery back into the logic board.
6. Put the bottom cover back on.
7. Reboot the computer holding the "Option" key.
I posted this originally here. Re: My Mac randomly just turned off and now it wont turn back on, the charger light is faintly flashing green and amber?!?!

Sudden Restarts on Mac Pro.

As of the past week or two, My Mac Pro has been doing sudden restarts.
The latest was in the middle of a film scan.
I set the scan up, walked away from the computer while it scanned and a few minutes into a 25 minute scan, the computer shut down and gave me the 'gong' sound. Upon the reboot, it gave me the error message that an unexpected shut down happened and do i want to send a report to Apple.
Yesterday i was getting the same thing. These mostly happen while the computer is idle.
The only difference with yesterday was that upon reboot, i got the error message with the power button symbol asking me to hold the power button down and shut down the machine and then restart.
I did a reset where i shut down the computer, and unplugged everything from the rear of the machine for a minute or so. still sudden shut downs.
I have read that this is common on the MacBooks but i have not seen anything on the Towers.
Please advise? i have a few months left on Apple care.
Thanks.

Seems like we have three different threads.
I don't believe the article on SMC RESET is accurate, at least leaving unpowered for couple minutes doesn't seem to work, try overnight, until they return to using a physical SMC button.
Run AHT in Extended Loop. And run Memtest. Marginal RAM is still bad ram.
There should also be a UPS, worth every penny, along with AppleCare - and do pay for extended warranty. Now.
Heat is always worth checking. Boost the fans. Monitor temp readings - Hardware Monitor is more accurate than freeware program iStat.
Clone your system and put it someplace safe off line on FW drive.
Run Disk Warrior.
Don't continue to use after a freeze or hard restart, repair it and boot from your emergency boot hard drive that has 10.5.5 (latest) along with Disk Warrior and other tools.
Do some maintenance. Onyx 2.0 or Leopard Cache Cleaner.
There WAS an issue with freeze and restarts on wake from sleep that was addressed (April?) with EFI firmware patch update.
Kernel panics are as varied as user setups. RAM, USB and FW devices AND cables. Tablets, input devices of any kind.
And if you don't stumble on why and solution, and a clean fresh OS (and be careful what you install, and double-check along the way) schedule an appointment to get it looked at, you're right, it isn't normal, but it could be something like a printer driver or connection too.

HELP!! Macbook suddenly frozen then the HDD was corrupted!

yeah my macbook suddenly went frozen then i restarted it but it wont turn on. i brought it to a mac service center and they said my HDD was corrupted, or broken and it has to be repaired in Singapore. They couldn't save my data as well. My question is : how could it be broken since i never drop it or anything? What are the possible causes regarding to a broken HDD? thx.

Hard drives just go bad--in PCs also. You just need to backup regularly to be safe.

I log in, startup bar starts loading but suddenly restarts

Macbook Pro retina, 2.5 intel i7, 16gb RAM, 512gb, OS X yosemite 10.10.1.
I bought this mac last weekend but i think since the last update this has been happening
I turn it on, put my password, the start up bar starts loading and suddenly restarts! I have to put my password again and just then it takes me to the desktop. This happens everytime i turn it on. Should i take it to apple?

I think you should make a Genius Bar appointment to show them your problem.

Problem with my MacBook Pro restarting on it's own repeatedly, ultimately corrupting my HD. (early 2008, running OS 10.6.8)

I brought in my MBP to the Genius Bar a couple of months ago, when this spontaneous-restarting problem had been followed by it not starting at all. They did a diagnostic, and then took it for four days, only to return it to me completely wiped after that time with no explanation, other than that "a file" somewhere on my HD was causing corruption. The Genius told me not to restore any of the files that had been on it previously, and it would be fine.
Well, that makes perfect sense. But, I needed the files to be on my computer, and since I had no idea how to determine which file would be problematic, I decided to just restore from my last backup (from the previous October -- bad, but not the worst scenario) and hope for the best. Well, now this problem seems to be back, and I'm hoping to get some advice for how to help make it go away.
In the past couple months since I restored it, I've had it crash suddenly, causing me to have to hard-boot the machine, and when I run Verify Disk from Disk Utility, it fails and tells me to start-up from my Install disk and run Repairs to fix it. I do the closest thing I can to that, which is starting up my MBP in Target disk mode, and connect it to an iMac which runs Disk Repair on it, and then it appears to be fine, until the next time it crashes.
Now, the probem has progressed to suddenly restarting with no warning and no crash, mostly right after I turn it on, and then doing so a number of times in a row. The console message (I think?) generated from this event is as follows:

With absolutely no ability to read these kinds of things, I did notice that several of these messages in the console started with 'airportd[20]', or somethign like that. This makes me wonder if it could be a bad Airport card?
If anybody has any ideas on how this could be happening, I'd sure appreciate it. I keep taking evasive maneuvers (i.e. Disk Repair from a different machine), but the problem keeps coming back, sooner and sooner. I don't trust the Genius Bar to help me understand this, so I'm leaving it up to you folks.
I thank you in advance.

The report indicates an internal hardware fault.
Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

Windows 8.1 Suddenly Restarting Again and Again

Hi everyone,
My PC has been suddenly restarting every so often ever since the windows 8.1 update. What do? It's really frustrating not being able to get any work done. Below are the last few DMP files. Thanks in advance!

Hi,
The latest minidump file relate with NvBackend.exe wich is a driver of Getforce device. Please reinstall its driver for test. Make sure it was upgraded to be latest at the same time.

* Bugcheck Analysis *
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff803bb599686, The address that the exception occurred at

My MacBook suddenly shut down and won't turn back on - how do I get it to turn back on?

My MacBook suddenly shut down after freezing up and I cannot get it to turn back on again. I tried the suggestions in the manual and none of them worked to turn it back on. Is there something I am not doing correctly? The little green light on the charger connector is green but not as bright as normal, it was charged by over 70% before it shut down, so I do not think it is a battery problem. Is there anything I can do to turn it back on? Thank you for any help given, I really appreciate it.

If it won't bong, then try an SMC reset.

Did you uninstall it this way?

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
Apple, please help!

MacBook Pro restarts unexpectedly after removing mini displayport-DVI adapter

Hi all,
I did a clean install of Mavericks a little while back. Since then I have been noticing an issue with my Mid-2009 17" MacBook auto-restarting, and have reduced it when I remove my mini displayport-DVI adapter.
I usually work with my macbook closed, connected to a Dell 24" external monitor connected via DVI. When removing the adapter the macbook quite often goes to the grey screen telling me that the machine must force restart. It is becoming really frustrating.
Anyone know about this issue or found a workaround?
Thanks in advance,
Ben

Hi emeidos,
If you are having intermittent forced restarts with yoru MacBook Pro, you may find the following article helpful:
