I am not great with computers, but I'm going to do my best to describe my issue and see if there might be a way to fix it. I did the automatic windows 10 upgrade a few weeks ago. Yesterday I installed a new CPU on my system nothing else changed. After the CPU install things went swimmingly. Had no issues until late in the afternoon when I started to get tab out crashes. At one point, after a tab out I could see everything on the desktop but I could not interact with anything except the program icons on the status bar. After attempting to close non-responsive programs from the status bar by right clicking and selecting close window, the machine shut itself down. As of this morning my machine will not successfully boot at all. It gets to the login screen and in the process of entering the password the machine ceases to function, restarts and goes back to the login screen. This happened several times in a row until finally the "Windows failed to boot properly" screen comes up. I cannot use system restore, it errors and fails. I cannot restore to a save point, it errors and fails. How do I do a clean windows install if I cannot start my machine up?
