Hooked it up to my monitor and still no joy...tried to start it in safe mode no joy,
So I took the side cover off...6 screws but limited access...lots of pop rivets seem to hold the case together,
Anyway I took the screws out of the power supply but only moves back about 50mm....un-plugged the hard drive and re-plugged it back in...powered it up and hey presto it lives again,
I wonder what it may have been....I did notice that the monitor socket on the rear was a bit loose..waggles about....
