Hey guys, Ive had my PC for a while now and its been running great. But within the past few days, my PC has randomly been shutting down, and I cannot figure out why. All my temps are perfectly fine, the PSU fan works perfectly and its fan side up on a desk. I clean my PC and filters monthly and my room is not very dusty at all. It will also shutdown whether I have one tab open, or am playing the Witcher 3 and streaming at the same time. What could be the problem? If you need anymore info just ask and Ill reply.
