Internal hard drives not recognised after disc use

3 days ago I tried to play a DVD in my macbook pro (mid 2012, 13 inch), I almost never use CD's or DVD's in it but anyway the computer completely froze and I had to force a shutdown. Then over the next 24 hours it would sporadically freeze from time to time and I would have to shut it down again. Then it wouldn't start up at all and the question mark folder appeared on start up so I restarted in recovery mode and repaired the hard drive in disk utility which fixed it for about 2 hours and then it froze again. Now when I turn on my macbook I'm getting the question mark folder and my hard drive isn't even recognised in disk utility or as an option to boot from. I don't think it's a hard drive failure because the hard drive is only 3 months old and because I put in another hard drive and it failed to read that one as well. I had the question mark folder problem 3 months ago and took it in to a repair shop and they replaced the sata cable which fixed it so I don't think the cable is the problem unless the new one failed after only 3 months. I'm really hoping it's not the logic board. Do you guys think the dvd was what caused it somehow? Do you think I'll need to get a new logic board put in or could it be something else?
