This one was EDF's fault though, a momentary power failure that switched
my Denon HiFi back to standby, and rebooted the PC, though I don't
remember the desklamp blinking but I may have missed that.

No that is right but the bad shut down can, and I found that a good clean

windows under certain conditions cannot cope with hardware on the blink very
well and either locks up or shuts down. Brian
