Question Mark Folder yet again

So I bought a MacBook a few months ago as a general light work machine.

Since buying it, I've had to replaced the hard drive cable three times and the hard drive twice. On the last occasion, I put in a new SSD, a new hard drive cable, and I've insulated the hard drive cable with electrical tape. But the question mark has come up again…

Any idea what it could be?

Couple of things, this video shows how to protect the cable from the rough surface on the bottom case where the hard drive sits:


These cables also get damaged on the last step of the climb from the bottom case impacted on that slightly raise area. I put 3M thick red tape on either side of the cable to prevent it from impacting. I also go to the more substantial 2012 13" cable on these machines.
