First run a live Image of 16.04 on the PC that is showing the problem
and make sure that it is, in fact, the Ubuntu version that is causing
the problem.

Also make sure that the Firmware (BIOS) is up to date on the
motherboard.  That applies whatever the results of the first test.

You said "One of the problems", I therefore deduce that there are
other problems.  It might be interesting to know what they are.
