Q: Aht will not complete

MMac was working fine till Yosemite upgrade, now when I power it on after logging in the Mac shuts down after 30 seconds of the pin wheel. Tried running the AHT test but it freezes during the logic board test.

MacBook Air (13-inch Mid 2012), Mac OS X (10.7.5)

Then try a safe boot:

Tried all the above, finally had to erase the drive and reload OSX, system is fine now. Not sure what caused the glitch. Thanks for your help
