iphoto, preview, imessage, Appstore freezing all at same time?

All the other apps are working just fine.

Only these iPhoto, Preview, imessage, and App Store is not working.

When I click on the top menu bar, the drop down menu doesn't appear and nothing happens.

I tried reloading my OS X Yosemite twice and the problem still persists.

Would Disk Warrior be worth a try?

someone have any idea how I can fix this??
