So basically my computer has ceased to function on the latest windows 10 update, 100% disk usage is occurring at all times leaving the computer inoperable and I've found that reverting it to factory settings and not updating fixes that. Well the other night I clicked on update and shut down accidentally rather than sleep. I immediately went to factory reset it again and it finished and put me at the setup screen, at that point my power went out. Upon turning the computer back on it came up with the screen That shows the windows logo and has a loading circle, let this "load" for about 2 hours before shutting the damn thing off and rebooting. It takes me back to the same screen where I proceed to give it 8 hours, finally it takes me to a screen that says administrator and has another loading circle, I have now been on this screen for an additional 8 hours. I have no Idea what to do at this point, I have tried to reinstall windows from a DVD and from a USB but for some reason it tells me to insert actual boot media, I have tried multiple different win 7 and 10 isos on dvds and usbs and none will work. Any help would be greatly appreciated as I fear this os is slowly taking my sanity. Thanks.
