I was creating a Word document running Vista Home Premium O/S. Suddenly it 'crashed'. On trying to reboot, the 'blue screen of death' briefly appeared. I inserted the system DVD and chose the 'Repair' option. After at least 15 minutes of checking it came up with the error message:
'A recent driver installation or upgrade may be preventing the system from starting.
Repair action - System Restore
Result Failed - Error Code=0x570'
It is not possible to start Vista in the Safe Mode. Is the only remedy now to completely reinstall Vista?
