Instead of different keyboard, You could also try to press power button
and wait a minute, which is separate from keyboard, and should shut
down your PC/laptop by default.
If the crashes are HW related and there is no kernel panic - there is
little you could do in the absence of logs. Is your fan spinning after
the freeze? How about hdd activity LED? Do you see anything on your
display?
If the crash/freeze was once off event you have nothing to work with.
If it repeats, you could try different distribution with different
kernel version to see if it helps. If it persists across distributions
and you cannot correlate it to particular usage, you could try
memory/CPU/storage tests if they trigger something.
You did not mentioned what HW (CPU/chipset/graphics) you have. openSuse
42.1 (kernel 4.1) often crashed with SkyLake CPUs due to graphics, so
if you have KabyLake (kernel 4.4) maybe you need newer kernel than the
default in opensuse 42.2.
