All factory installed software stopped working

[nconnella]

Ok, so my new 2010 MBP just went to hell on me. All of a sudden all my factory installed software such as ical, dictionary, stickies, photobooth stopped working. They wont open in any way, either dock or applications. I've deleted plist, repaired disk permissions and repaired disk... nothing. Third party apps, safari and iphoto work. But iphoto froze when I open it. Apple wants me to reinstall the OS but I would like to avoid if possible. Anyone else know what this could be?

Sounds like corrupt preference files to me. Try completely removing and reinstalling the apple software. Google can provide directions on this for you.

Maybe your HD is failing. Check its SMART status in Disk Utility.
