Windows stuck at windows startup

I just made a restore point with my windows 7, the restore point date was yesterday. After that getting that shutting down and restore point stuff, my computer restarts. But it gets stuck at windows startup. I shut my pc down and tried again but it's still stuck. I tried booting in safe mode but it gets stuck at 'CLASSPNP.SYS'. I trid those other safe modes, like with networking, etc. Still gets stuck. I tried using Last Good Known Configuration, it still gets stuck in "starting windows". I tried startup repair but I only get that blue windows sceen, just that blue background with the white designs without any texts. I tried all of that again and again and still no change. I tried starting windows normally, again it's still stuck. I don't have any windows 7 installation disk I don't know what to do please help.
