So I bought an Asus K55A-XH71 about 3 months ago. Everything worked fine until I downloaded something and it never completely downloaded. The laptop didn't really work after that and I had to reinstall windows. The laptop somewhat worked after that. After I shut it down and tried to turn it back on, it goes straight to startup repair. I've tried everything to fix this, but it goes to startup repair every time I turn on my laptop. I've tried system restore, command prompt, image recovery, and even safe mode doesn't work. I don't have a recovery CD. Please help me.
