Full computer crash, often on last iteration

[owochle]

Hi,
I've been trying to generate images but my computer does not want to. It often crash on the last iteration, and turning my pc into a sort of zombie mode, where everything is turned off inside, the power led is on but even the physical reset button does not work. Do you think it's a PSU problem ? I know my psu is quite low for my setup, but i never had any issues before, even when rendering things on blender. Or maybe it's just drivers problem.
Have a great day
