I apologize for the late reply it took some time to back up a couple hundred gigs of steam games, then put them on a cloud. so i have reformatted and re-partitioned my drive, so far so good. i have installed Overwatch
and played for about half an hour, and i didn't experience any freezing. i will continue to test various games and programs today to see if the problem is resolved. and will try update you by tonight before 10:00PM my time.
Thanks so much for your help this far.
