I recently bought a new computer (i9, 32gb ram, 1ssd for linux, the other for win). Here is the "inxi -Fxz" output:

Everything ok with the installation and installing the usual software. Now Im running a scientific program (which is basically performing operations with matrixes during 200000 iterations and save results and was written in C) and the computer freezes in some ocasions (it doesnt happen in the other pcs where im testing, with linux mint also).
I did some tests:
- If I open the normal programms, such as firefox, text editor and the computer turned on during a day, nothing happened. It did not reset.
- I tryed to run the program with 3 different parameters as input. Im running the single version without any parallel lib. Nothing happened.
- Then I run the program for the 3 different parameters at the same time, running them at 3 different terminals (using 3 cpus), the computer freezed after some time. This does not happen in the other computers Ive tested the program, including the desktop where I work, with the same linux mint version. Then I did the same teste and it freezed in different iterations.
- Then I ran the program 3 times separately again. It freezed. So this seems to be random.
What can I do to find the problem? Can this be something due the hardware? Im not a computer expert. Drivers were updated from the "Driver manager". I use it basically for my work to run my programms.
thank you so much
