So I downloaded a program that cleans unused files and unneeded files. Apparently it erased some kind of startup files or something cause I shut the computer down one night and the next morning I went to turn it on and it just goes to the blue screen and the loading icon comes on for 5 minutes. It is a Macbook and after sitting there for 5 minutes it just shuts down and tries to start up again. I don't know what I have to do to restore it cause it removed my thingy called "Matt" which is I guess my hard drive name. I'm not every good with computers so I dont know all the names for things.
 
I've seen this happen before. Often times this is caused by a file that's become corrupted during an update to the computer, or something along those lines.

You need to do what's called an Archive and Install. What this does is reinstall Mac OS X onto your computer, but doesn't touch any of your personal files -- so all your stuff should be safe. Unlike a Windows PC, Archive and Install DOES NOT erase the hard drive, but you just have to make sure to follow what's in bold below, and you'll be all set.

You need the CDs that came with your computer to do this.

Info from Apple's knowledge base article:
Start up from your Mac OS X Install Disc 1 or Install DVD. If you have different versions of Mac OS X Installer discs (for example, if your computer came with version 10.3 and you later purchased and installed version 10.4), start from the disc that most closely matches the installed Mac OS X version. Usually, that's the latest (newer) version.

Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C.)

Select your language. The Welcome to the Mac OS X Installer window appears.

Click Continue. The Important Information window appears.

After reading or printing the information, click Continue. The Software License Agreement window appears.

After reading or printing the information, click Continue.

An agreement sheet appears. If you agree with the license agreement, click Agree. The Select a Destination window appears.

Click the volume that you wish to install to.

Click Options. The installation options sheet appears.

Select Archive and Install.


You should also select Preserve Users and Network Settings, to preserve network and Home directory settings.

Select the volume which already has Mac OS X installed.

Click OK.

Click Continue to begin the installation.

Then just wait until the process is completed. :) If all else fails, call Apple. They're the best.

I tried that first about a week ago. All my computer lets me do is select the language then it says "Mac OS X cannot be installed on this computer"
 
This problem is usually started by 2 different things (unrelated), I've suffered from it from time to time and is usually easily fixed

Try the following list 1-8, stop once you've got it to work.

1) Start disc utility and select your primary (mac os x installed on) disc and repair the file permissions. Unix being a modern operating system with a huge amount of system related files. Sometimes some of them get corrupted. This usually fixes the blue screen at start-problem.

If you never get a chance to start the disc utility then insert the mac os x install disc, start while holding "c" down and run the included disc utility from the menu bar on top.

2) start up in normal mode. Is the problem fixed?

3) if this didn't fix the problem then (I presume you have auto login by default) try to log in on another user, another common related problem is bad start up items. Remove all start up items from your primary user.

4) start up in normal mode. Is the problem fixed?

5) Call apple, they might have some other easy solution (given you still got apple care for _any_ computer)

6) try Archive and install, might work now that permissions are fixed

7) Try installing mac ox x on an alternative external/internal drive. Transfer all files. Install max os x with a formated drive and transfer back all files.

8) if you've reached this get to an apple store and hand your apple in. It might be something serious.
