MacBook Air freezes and then won't start up (interrogation folder) So I own a MacBook air Air 13 11" which worked fine for about 15 months after I purchased it on Adorama.

One day, I was using it and it froze. Command+Option+Esc would't work so I had to push power button to shut it down. When I turned it back on, it showed me the interrogation folder. Internet recovery didn't work and the computer couldn't even read/recognize the internal SSD. So I got the SSD replaced and the computer worked fine for a week. Then, same problem again. 

Sometimes I turn the computer on and it works fine. Sometimes it gives me the interrogation folder. Today I froze 3 times already. Then I have to open it, take out the SSD, put it back on, turn on the computer. It works for a while and then it freezes again...

Ever happened to anyone? Any idea what could be going on?
