Interesting problem

About 2 weeks ago I decided to remove the indexing of files on hard drives. After this operation, I reboot the computer and when it comes to loading Windows (Windows logo), the hard one stops blinking, then it hangs, you can wait at least until the second coming, I do a reboot - everything loads fine. than the problem - it turned out to be in AODriver 4.2.0 - it got damaged, while indexing, I tried to restore it without a head. The computer itself works fine, the problem is only in loading the OS, sometimes you have to reboot more than 10 times to boot. I don’t want to rearrange the axis yet, a lot valuable programs. I checked the system for hardware problems - purely. Maybe someone has some ideas?
