I installed the patch described in the email received and when I loaded Live mail 2012 it deleted itself. I decided to restore my PC back to Dec 4th which was last restore point.

The PC rebooted and I got the Blue screen saying error occured and would reboo.t the reboot failed in the same way.

As I had a system image on an external from a week ago I decided to restore that.

This failed as it informed me that the hard drive was corrupted.

I then decided to rebuild the PC using a copy of Win 10 version 1511, this started and informed me that the hard drive was incompatible format Bios

Trying to read the hard drive on another PC it was not recognised. I then installed a new drive into the failed PC and everything installed OK    Luckily all my personal files were backed up.
