Hello! I'm new so I'm hoping I'm not posting this in the wrong section. So a few weeks ago I was skyping when my macbook pro (I think it's a late '11 model) froze and I had no choice but to force its shut down. I restarted it and got the awful flashing question mark folder. I tried to do Internet recovery, but when tried to reinstall the OS it showed no disk. I did my reading and guessed it was probably the hard drive cable that was failing. I just moved to Mexico city, so I really have no clue where to get new parts, but I managed to find a used cable to replace mine. I replaced it, and when I turned on my MBP, it took a bit to load, but everything was working as I left it. All the programs I was running when it failed, were opened, all my chrome tabs as I left them... all my files intact, etc. I was reaaaally excited, and I left for work. I didn't come back home until the next night, and when I tried to turn it on, there it was, that stupid folder with the question mark. I restarted the mb a few times until it worked again, but then again, it froze and I had to shut it down. Now I get the folder again and again, even when I reinstalled the cable a few times, and even tried my old cable too. So my question is: if all my files were intact and the hd seemed to be running just fine - not slow or anything- should I suspect I need yet another cable? or could it be that the HDD is at fault? Or maybe even the logic board? I hope you can help me, cause I am pretty ignorant of these topics. Actually, this is my first time ever handling with hardware repairs. Thank you in advance!
