I am not sure if this is the same problem or not but here is something that may help. I have seen this many times. it turns out that it is a virus. I believe it is pakes virus. The only fix i could find was to remove the hard drive and scan the drive with another machine. The only software I have ever used to do this was kaspersky antivirus. You can download Kasperky trial software and scan with it. Once this scan was done I was able to put the hard drive back in the machine and get into windows and run Malwarebytes and other tools to completely clean the system.
