IPhoto unexpectedly quitting on BRAND NEW MacBook Pro

Question

I just bought this computer a couple of weeks ago. I used to have a MacBook, and all of a sudden (after 4 years of loyal service) it began having issues. So I bought a new computer a couple of weeks ago. It is the MacBook Pro 13" basic model. It has absolutely no upgrades, thusfar. All I have done is add my wedding photos to iphoto. There are around 2000, all ultrahigh quality. Yesterday iPhoto unexpectedly quit. This has happened a couple of times now, and I am also experiencing lag. I turn the computer off regularly, I don't download anything from anywhere but itunes etc. Why is this happening? Is it simply the amount of photos on my computer? When it quit unexpectedly I was editing my photos(playing with contrast, sepia, etc.). I am getting really frustrated, because these are the same issues that eventually drove me to buy a new apple. With such a big investment (for a college student) I am really upset about this issue. Please help me!?

Answer 1

Try this:  launch iPhoto with the Option key held down and try to create and use a new, test library.  Import some photos and check to see if the same problem persists. If the new library crashes try the following:  make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
     User/Home()/Library/Caches/com.apple.iPhoto folder.

3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
If the test library works as expected then the problem lies with your current library.  In that case
make a temporary, backup copy if you don't have a backup (select the library and type Command+D) and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot. 
Fix #2
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next  window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
