... and more. The original (apparent) hibernation problem would appear to have been merely a passing symptom of something much nastier
The subject machine is, now, totally inaccessible - no display output, no bios beeps, although the power up sounds normal, as far as running processor fan, mobo led etc. are concerned. Rather more worrying is that my standby 'checker' machine has become similarly comatose. This has left me with no means of isolating problem components. However, a third machine COULD be brought into the equation but I'm reluctant to do so in case there is something nasty being passed from machine to machine. Both 'pooters' are running Gigabyte mobos, different models, one (the standby) having O/B display but since I can't access the bios, I can't see whether this has been enabled. I have tried both PCI and AGP display cards on both machines but no success.
I can't quite believe that two reasonably well 'specc'ed' machines would coincidentally turn their toes up at the same time but I have run out of any further ideas for checking/fixing. The Post Mortem card, by the way, goes through its light sequence but the English translation manual is NOT as it describes itself 'pellucid'.
Any suggestions would be much appreciated
Finally, on a completely different machine - this one- the 'three fingered salute' doesn't work!! When activated, I get a dialogue box saying that this function has been disabled 'by the Administrator'. I am that Administrator and I

well haven't!!

I can't find any instructions as to how to re-enable it - again, any hints would be appreciated.
TIA
