I''m with Brando here, if you upgrade to 10 with the system in that state, you will end up with a troubled 10 installation.
First fix these issues ...
How?
Try and check eventvwr for disk errors.
Check whether you are overclocking, if so, clock it down back to normal.
Check your Sata cables ... are they still nicely connected ...
Run an extensive memory test?
Backup, yes, good, regularly, yes, good stuff. Is. Backup. It, schnizzle and stuff...
