I have spent a good part of the day trying to fix the user profiles for a vista machine. I have tried the reg edit, ran cleaners and anti virus malware bytes, hijack this. I have tried to make new users but when i try to log into them all i get is a blue screen and the hard drive is writing of reading. This is a business machine and not sure if i can do a restore point without losing info for it. I do not have a disk . It is a e-machine W3615. Any help would be welcomed.
