Please use inline posting style and proper indentation.
Phew... will be quite hard to read. But here you go.
It is not hard when you delete the portions that you are not responding to.
Have you cleaned the system interior, filters, fans, heatsinks,
ducts,
etc., recently?
As written in OP, the system is new. Only PSU is used. So it is clean
Okay.
What is a thermal solution?
Heat sinks, heat pipes, water blocks, radiators, fans, ducts, etc..
What stresstest are you using?
stress running in s-tui
Do you mean "in situ"?

I prefer a tool that I can control. That is why I wrote the previously
attached Perl script. It is public domain; you and everyone are free to
use, modify, distribute, etc., as you see fit.
Have you tested the power supply recently?
It was working before without issues, so not explicitly tested.
I am not building regularly, so would need to borrow such equipment
somewhere
Understand that an ATX PSU has multiple stages that produce +12 VDC, +5
VDC, +5 VDC standby, +3.3 VDC, and -12 VDC ("rails"). It is common for
one or more rails to fail and the others to continue working. Computers
exhibit "weird behaviour" when this happens.
Just spend the US$20.
Have you tested the memory recently?
Did you do multi-threaded/ stress tests?
Yes, stress is running multiple threads. Only on 2 threads it was
stable so far. However it takes longer for the errors to come up when
using less threads. might be that I did not test long enough.
I use Memtest86+ 5.01 on a bootable USB stick. In the "Configuration"
menu, I can choose "Core Selection". It appears the default is
"Parallel (all)". Other choices include "Round Robin" and "Sequential".
Memtest 5.01 also displays the CPU temperature. Running it an Intel
Core i7-2600S with matching factory heat sink and fan for 30+ minutes,
the current CPU temperature is 50 C. This leads me to believe that the
memory is loaded to 100%, but the CPU is less (perhaps 60%?).

I recommend that you run Memtest86+ in parallel mode for at least one
pass. I have seen computers go for 20+ hours before encountering a
memory error.
Did you see the problems when running Debian stable OOTB, before
adding
anything?
I would need to do this with a liveUSB, to have it run OOTB
Okay. Put my Perl script on your liveUSB. Also put some tool for
monitoring CPU temperature, such as sensors(1).
