Mac book frozen, won't turn off or restart. I don't have any programs open.

First thing this morning my computer is frozen, it won't turn off or restart. I don't have any programs open.

Yes if your model MBP has a removable battery. If it does not:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

K7N2 Delta ILSR won't turn off, just restarts

K7N2 Delta ILSR won't turn off, just restarts. Every time I click on "Turn off computer" in Windows XP, it shuts down, but restarts again. Could this be OS related, or perhaps Bios related. My other machine, almost identical to this one, except that the other machine has BIOS rev 7.6 and this one 7.2.

PSUs seem to be yr favorite subject, but I'm afraid this time it's software. I experimented some more as the problem only occured after installing the Nvidia drivers. Comparing the system settings in the device manager before installing drivers and after installing them, reveils that the problem shows up when AGP HOST TO PCI BRIDGE is installed. When killing this item the PC shuts off properly. Unfortunately when turning back on, Windows automatically reinstalls the PCI bridge and I have the problem again. LOOKS LIKE A MSI SOFTWARE PROBLEM !
By the way I have a PCI graphics board and not AGP in the failing PC (the good one has AGP graphics).
Now what?

Mac Book Pro won't turn on

I have a september 2008 Mac book Pro 15". Last night it switched itself off for no reason. I was able to turn it back on again and carry on using. Today however it won't turn on or do anything. I have checked the battery and it is charged. The power adapter is also fine (tried a different one as well), but when I press the power button, nothing whatsoever happens. Anyone got any suggestions?! Thanks

See if this offers any assistance. if not, then a trip to a repair facility is in order.

Mac book pro won't turn on after after accidentally shutting it down during updating

Please help, I was updating my Mac book pro and accidentally shut it off. Now it wont turn on, it shows the apple logo and the continuous cycle circle.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your 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 hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to a pre-2013 Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Mac book pro won't turn on mavericks

I successfully upgraded to Mavericks 2 weeks ago and have been having sporadic problems.
Today my Mac Book Pro 15" 2012 edition (not retina) turned off while I was using it and will not turn back on.
Anyone have a similiar problem?

Hello ColeSF,
It sounds like you have been using OS X 10.9 for a bit and suddenly in the middle of using it, the computer shut down will not turn back on. I was researching what could be causing this to happen and found this article that should help you troubleshoot the issue named:
Troubleshooting: My computer won't turn on
http://support.apple.com/kb/TS1367
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Mac Mini fan won't turn off (only while powered on)

Unlike some stories i've read while crawling around the internet trying to solve MY problem, it's not that my fan won't shut off EVER. The fan shuts down when i put it in sleep mode or shut down the Mini. No problems there. But while the computer is in operation, the fan runs non-stop.
It wasn't always like this. In the 2.5 years i've had my Intel Mac Mini, it has more and more frequently employed the fan. As of the last couple months, the fan is now in continuous use, as long as the computer is in operation. In addition, all the programs take much longer to load, and i'm dealing with programs crashing (Firefox & Safari far more than anything), Bluetooth not functioning, and the front light on my Mini is out.
As for the fan, the Mini is getting plenty of breathing room...even more than it had before the problem. I also have 22GB left on my Mini's hard disk.
Are all these problems related? Am i really just working on my last thruster here? Is my dilitium crystal just about dead? Is a warp core breach imminent? I do not have AppleCare, and i don't know if the Apple Store would look at it for free if i brought it in. Any help (no matter how small) would be greatly appreciated.
MY STUFF:
Mac Mini - 1.66 Intel Core Duo, 2G 667 HHz DDR2 SDRAM
Iomega MiniMax 1TB external HD (for audio/video files)
Iomega Minimax 1TB external HD (for Time Machine)
OSX 10.5.6

When you start your mini from cold (after at least an hour powered down) does the fan spin up to full speed immediately, or does it start out normally and then speed up after a few minutes or so? Did you have the system open for any reason just before this behavior started?
If you had the system open, it might be something as simple as the fan control cable that is not connected. When disconnected, the fan will run at full speed all the time.
It the fan runs at full speed almost immediately from cold, then it would suggest one of two things: either the system is suffering from something like a loose heatsink, or there is an errant process running that is putting the system under heavy load. You can check that by opening Activity Monitor (in Applications>Utilities) at looking to see if the CPU load is consistently high. If it is, look for a process that is causing it.
If the fan runs quietly at first, and then speeds up, after a few minutes, then it does seem likely to be a heating issue. Aside from making sure the vents around the base and on the back are clear by using a good vacuum cleaner, it's possible there is enough debris inside to obstruct the airflow. If you've opened up the system previously for any reason, now might be a good time to do so again, for a quick inspection and clean out.
I would also perform an SMC reset if you have not already done so:
To reset the SMC on an Intel mini:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
And to ensure you are not suffering from a range of broad 'tuning' type issues, download a copy of YASU (http://jimmitchelldesign.com/projects/yasu/) and run all tasks. This clears cache files, resets logs files, updates prebinding, performs a permission repair and a few other tasks. After the reboot (which will be slower than usual) your system should run a little better.
... i don't know if the Apple Store would look at it for free if i brought it in....
You can make an appointment at the 'genius Bar' of your local Apple store - they will look at your system for free, and help with a diagnosis. What they generally wont do without charging for it is anything that involves opening the system up. However, it's worth paying them a visit for a bit of hands on work!

Mac book pro won't turn on and battery is fully charged..

My Mac book won't turn on... The battery is fully charged, we have it hooked up to power... We've tried holding power button down and disconnecting from power but nothin have worked! It makes a noise like its going to turn on and little white light flashes but nothing happens

Try a safe boot, see if it starts, this takes a bit longer. Push power button while holding shift key, continue to hold key till you see the progress bar. If it boots, shut down and try to boot in the normal way. Best

Take it into your local Apple Store or an AASP. You shouldn't be having those sort of problems on a month-old computer.
