ok I think your hard drive is in good health
installing updates can take a very long that's normal
its probably not hardware it's just that your windows 8.1 got corrupted
and your recovery flash drive is probably corrupted also
clean installing windows 10 would probably be the best option
if need help with partitioning windows 10 just tell us
