Randomly shutdown may be caused by BIOS.
However, if this happens when the machines is moved, I suspect bad solders.

Do you know where the problem could be if this is due to bad solders? And if this is due to bios how can I solve it?

You should try new BIOS, clean ME.
Don't forget to make backup first.
