I suggest you check the date on your Mac.
When you are in macOS Utilities, open the menu "Utilities -> Terminal":
A Terminal window will open.
Then type the command
date
and validate the command with the Enter key ( ↩︎ )
If the date does not match today, then you need to set the correct date.
Here is the syntax for the "date" command:
date mmddHHMMyyyy
with:
- mm: the month (01, 02, ..., 12)
- dd: the day (01, 02, ..., 31)
- HH: the hour (00, ..., 23)
- MM: the minutes (00, 01, ..., 59)
- yyyy: the year (2016, ...)
Example:
Today is December 11, 2016, and it is 09:47, so you need to type this:
date 012911472016
(the segment 1147 corresponds to the time, remember to adjust based on when you read this message ;) )
then validate with the Enter key ( ↩︎ )
Now quit the Terminal and restart the Mac OS X installation.
The charger must be connected because if your Mac shuts down due to battery depletion during installation, you'll be in for some serious trouble.

How do you install the OS? With a CD? A USB drive?
Is it the right version of the OS? Have you changed any components of the PC?
And I see that the topic is marked as resolved; if it's not the case, I invite you to change it back to "unresolved" to get help from other contributors ;)
