[QUOTE="greg2011, post: 1571137, member: 196375"] Hi Nick. You were absolutely right, more hardware diagnosis revealed faulty RAM. The reason techtool pro passed RAM test few times is simply because any software cannot test whole RAM because some of it is being used all the time. I used memtest in single mode which diagnosed RAM fault clearly. At the moment I am trying to return this MBA and get my money back. Although the seller described it as faulty he assured me that the hardware has been tested at Apple. I doubt it. Thank you so much for your help. I have learned so much from this experience. Thank you [/QUOTE]
