actually it happened again moments ago and i think its due to my psu and not winodws as now its just shutting down abruptly with no notification or anything, (if you see my previous thread) i was using a faultyish psu which shut down after about 10 mins when playing games, and never any times other than that, but now after removing the gpu,now though its shutting down by itself even when not playing games after uninstalling the gpu
