in addition to possibilities above, have you checked the optical drive. i've seen a few (but not many) that act this way when the cd or dvd drive is starting to fail. good luck
pay first, then receive, that's the way i've always done it. use a credit card on large transactions, and ship to the cc billing address. if you get scammed, then turn it over to the credit card company. i won't mess with no pay bastards, i'll let the card companies deal with it.imo
