Bertram, everything about your various issues suggests hardware to me.
Memory is usually the first thing to check, but all sorts of components
can go flaky, sometimes in almost non-deterministic (ie, weird) ways.
Have you tried the suggested memtest86 test, for at least an hour or so?
Another useful tester is sysutils/stress, which may be installed and run
without rebooting or other inconvenience. Something like:
# stress -c 2 -t 1200 &
will run 2 CPUs at 100% for 20 minutes in background; adjust to >= cpu
count. Meanwhile keep an eye on system temperatures and fans; this gets
CPU/s as hot as they can. Your system should be engineered to cope with
running at full rated load, with some headroom.
