Replaced the cable and booted the machine back up. No errors. It instantly started running disk check and got through with no errors. I ran samsung hard drive check, no errors. Ran the game I was playing a while back. No errors.
I guess this whole time it was just the stupid cable. I can't believe that wasn't the first thing I should have checked.
thank you for all of your time and help! I really do appreciate it. Mystery Solved!
