Some new things I tried: 1. I now shut-down using "hibernate".
When I next switch on the PC, it boots up quickly to the log-in screen, which behaves with no problems. I don't know whether this is a good long-term solution for me... 2. I did a complete fresh install on a separate hard drive. I first tried the install on the PC that is having problems. The live CD could not boot. So, I installed the system on another PC. I then put this fresh HDD in the problem PC (while the PC's normal HDD was disconnected). It had exactly the same problem during boot - it froze up at the sign-on screen.
