I have a T460S which is behaving very strangely. It has recently had Windows 10 reinstalled onto it, but shortly after installation, the machine seems to corrupt and restart, at which point I cannot log onto the user account - I get the error: "The ProfSVC service failed the sign-in. User profile cannot be loaded" This leaves me stuck because there is no other user account with which to log into Windows. I tried reinstalling again but I get exactly the same thing - the machine installs a few drivers and then corrupts and restarts and I can't log on any more. Does anyone know what could be going wrong here? I've run all the onboard hardware diagnostics and they've all come back as ok.
