ntfs.sys startup error, please help
So when I start up my windows 7 pc, I get an error about some thing called ntfs or nfts whichever one. Basically what happens is the computer starts, it says starting windows and during the animation (at the same spot in the animation if that matters) it freezes, turns blue for a split second with a huge amount of text that I can't read in that short amount of time, then shows a technical looking menu called system restoration or some thing, error recovery I think. It had 2 options; start windows normally, and start system restore. (I'm at school so I can't remember the exact messages). If I click the start windows normall option, it starts the pc again and eventually goes back to this menu. If I click the record ery option it says "loading windows files" then a blue screen and that is where i get the ntfs.sys error. I have heard that running CHKDSK fixes it, but I'm 100% locked out and have no way to do so. If anyone knows the cause of this or how to fix it, please tell me.another thing is that I (foolishly) turned the pc off with the power button, if This was the issue. I got my pc recently and it costed $1.6k and now I can't use it, so I really want any info you guys have.
