I have a Lenovo y500 that is running windows 8. Whenever I boot it up, it takes a while then says there's something wrong with the drive. Then it says "preparing automatic repair" for a while and eventually goes to a blue screen, from which I'm unable to boot up windows. It used to give me that option, but it never worked anyway. Before this started happening, my hard disk usage was locked at 100% for some reason I could never figure out the the laptop was running unreasonably slow. Last year my laptop's hard drive gave out and I had to have it replaced. This is acting like a different problem but I wonder if it might have the same solution.
Added (1). I tried resetting the laptop to factory and reinstalling windows. It worked for a little while, but when I tried to reboot my laptop, it went back to the same old stuff and continues to not be able to boot up.
