Spinning wheel, system crashes, iTunes is crashing

Question

Hi,
I am having major problems with my Macbook air.   iTunes constantly crashes...I have some software issues where they crash as well... I constantly get the spinning wheel.  So I did a EtreCheck and there are the results... Any help would be greatly appreciated....Diagnostic was done (holding D on start up) but I don't know how to test my hard drive... It's a new version and running Yosemite 10.10.1 which you'll see in the report.  Thanks
Problem description:
I constantly get the spinning wheel.  When I run verify disk, I get about 30 or 40 disk permissions to repair.  iTunes isn’t working properly.   Keeps crashing, reinstalled it still the same…
EtreCheck version: 2.1.5 (108)

Answer 1

Start the MBP with the OPTION key down.  You should see a display such as this:
Select the Recovery HD.  It should result in a 4 option menu like this:
Select Disk Utility.
Run Disk Utility>First Aid, Verify and Repair.
Ciao.
