When I setup my new computer, I put in an administrator password when it asked me to. After the system reboots, my password doesn't work and I cannot log in at all? I also cannot get it to start up in safe mode to try and log in that way. What can I do now?
The most possible answer of your problem is to enter the password in caps lock on mode (because you may have entered your password on caps lock mode), check your keyboards all the keys are working properly.
