You probably need an OS-Reinstall. Take it to the apple store and see if they'll do it for you. If they don't there are third party Macbook Repair services that can fix it for you. There are also free Macbook Repair guide that show you how to restore it yourself. You should still have your install CDs to do the restore.

Restart appears on start up


Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

I restored my computer's HD using LaCie. Now, my Macbook won't boot us using it's own HD, just LaCie


Hi SuzanneHow did you do the install? It's important that you do the correct procedure. First you should have installed the OS from the disc thaty came with your MacBook. It would have then asked you how you wanted to procede. One of the options is to restore from a back-up or from another drive.
You pick the Lacie and let it do iots stuff. As a rule, when that finishes the machine restarts from the new drive.
What you can do to check is shut the machine down. Hold down the Option key (alt key) and then press the power button to start it up again - don't let go of the option key. After one or two moments you will get a grey screen with a two icons. One will be your HD and the other will be the LaCie. You then choose which onwe to start from and that should be that. If you only get the Lacie showing up then it measn that you do not have a system on the internal HD and that it needs to be restored from the CD/DVD.
Let us know what happens.

Computer froze, I tried to restart but it would not shut down. It is now stuck with only background showing. Can you help.


Press and hold the power button for about 10 seconds will power off the MacBook Pro.

You can then try turning it on again normally.

If the problem with freezing reoccurs on start up, then hold down the power button again, and turn it off. Unplug the MagSafe Power Adaptor from the MacBook and the Wall for several seconds. If the battery is removable, then remove it, wait for a few seconds and re-insert it. Plug the MacSafe back in if desired. You should now be able to start up the MacBook with no problems.
