Had this issue where upon entering the majority of my games my pc will crashes after about 15-20 seconds. Orignally this was coming up as Kernel-Power error 41 but I've fixed that, and now I'm getting DeviceManagement-Enterprise-Diagnostics-Provider error 454. After fixing the error 41, most of my games work again, its just the highest intensity games e.g. Rainbow Six Siege, that still crash. All of my drivers are up to date, I'm on the newest version of windows 10 I can be (1903, I updated after experiencing this issue to try to fix it), my drives aren't fragmented and my pc definitely isn't overheating. Apologies, im very new to PCs so don't know much info to give. Also sorry if this is in the wrong section
