Black screen on startup and takes forever to start!

Hi all. I have Hp pavillion Windows 8.1 It takes forever to boot up from the black screen. It has been freezing too. I ran the Scannow it says some files are corrupted and I saved the log in my documents if you want to see it.

Also for some strange reason my pointing keeps circling like my computer is downloading something. Weird!:(
I would so appreciate help from a professionals here.

Thanks
