Hey, I know this is a really late reply, but I'm getting the same issue you're getting, and I don't know how to fix it either so I'm wondering if you've figured out a fix in the meantime.
Sorry dude, it turned out to really be my Hard Disk so I had to replace it entirely and lost pretty much everything, it's now sitting in my room on a shelf waiting for me to figure out on how to extract the info from it but I am not even sure if that's gonna be possible since it was about an year or more ago and how much it's gonna cost me.
But yeah in general Windows was also giving me all sorts of errors and was booting very slowly so I gave the entire computer to a shop and they told me it was definitely the HDD. Asked them if they could somehow back up my info or something and they said they don't do that there or something, well it was just one guy since I live in a small town and it's a problem for me to go to the city but anyhow. At any rate if you're having the same issues as descibed by me here you're probably going to be in need of a new HDD real soon so I suggest to back up your info or at least most important such and get it over with because it's only going to get worse from here on.
