worried

Toast french loaf with margarine, coffee

i’m a little worried of my macbook. There has been some some hiccups over the past few weeks like sudden quit of applications and few days ago, failed to launch Suitcase. i ran a Disk Utility check and found some errors which could be fatal. Need to finish as much work as possible so that i can run another detail check with a high possibility of sending the laptop for repair and be mac-less for at least 3 to 4 days :(
