Random freezes every 5-10 minutes never happened before

ok well i’ve done a few firmware rollbacks and updates and nothing has fixed this issue, but now i can no longer change firmware (im going through the entire list in hopes i get a stable one for 1080p) i have changed the version in notepad but the player is not picking up the new FW on my USB any ideas, and is it at all possible that a WD rep can contribute as to why this has all of a sudden happened
