Well, to be honest, that screenshot just shows your idle temps. It's not really an indication of anything.
What was happening when the PC crashed? Can you replicate it? Try running a demanding game. Then alt-tab out of it (with HWMon running) and take a screenshot then, when the PC is at load and is working hard. Then we can better judge if there's something that doesn't look right.
Also, list your full PC specs, this will help us figure out some stuff too
PSU, CPU, GPU, ram type/density, mobo etc.
