If this were my box I think I would do the following:
If possible take a “snapshot” of your working directories by booting into the box from a live CD or flashdrive and copying the user data (e.g. Desktop, Documents, Pictures, etc...) to a separate drive to preserve them.
From the separate drive check the disk performance and error rate. Replace the disk if you find it defective.
Install F21 fresh and keep a secure record of the password.
You might do well to expand upon #2. Perhaps it is time to open the box up, blow the dust out, check the connections, and replace the CMOS battery as those silly batteries can cause a bunch of crazy problems before you find them. As well you might run some hardware testing software to make sure everything in the box is working well.
.. just some thoughts ...

Hi again,
I tried with rd.break or init=/bin/sh but I failed with both.
rd.break boot and I have a shell but it miss the passwd command and touch.
I tried with /sysroot/bin/passwd but it lack some library.
and I tried with /sysroot/bin/touch /.autorelabel and it worked.
anyway the pc does not want to boot.
it stop when it begin to start some service like "volatile and temp
files creation" or something like that. And other service like avahi..
login... ntp.. and firewalld.
it looks there are some problems with dbus...
