Vista PC was working fine yesterday. It is on automatic update, obviously installed something and rebooted overnight, Now it gets stuck at the Microsoft temperature bar (don't know the technical term) and will not progress from there into Windows.
I have tried booting into Safe mode from F8, however, although the PC seems to recognise the keyboard within BIOS setup etc., the keyboard does not seem to work at all on the screen where I have the safe mode option. The arrow keys do not select anything, Enter has no effect, so the PC just waits 30 seconds then tries to Start Windows Normally, which just has the same result.
I tried to boot from my Vista DVD, but in spite of selecting this as top priority in the Boot sequence in BIOS, the PC does not boot from the DVD, it just goes back to trying to boot from HDD. I do not seem to have an option to delete options (such as HDD) from the boot sequence and I do not know if there is an easy way to force a boot into Safe mode.
So I seem to be a bit stuck.
