So i've recently built my computer it's about 1 month old. Everything ran like a dream until yesterday. There I was surfing the web, nothing too demanding then BOOM! computer turns off unexpectedly. I try to turn it back on but i can't, im forced to unplug and plug it back into the outlet then it'll turn back on. So i thought it might've been an overheating problem, check the temps and showed they were great, the CPU and GPU, system temp was 31 C. So then I though my GPU might've been to demanding for my powersupply, but it ran fine while playing heavy games like farcry 3 for 5 hours in one sitting, never hitting above 71 C. Anyways, these shutdowns continued to happened at least 5-6 times throughout the rest of the day. So i checked event viewer and it shows up that I had a Critical error the time my shut down would happen, stating "Kernal-Power event ID: 41." Do you think that It might be the powersupply is crapping out on me? I did recently replaced 3 case fans for more air flow, but I doubt that would cause any of this. My full specs are:
