Wow... that's most certainly interesting. Anything is possible,
however. I can't tell you if a TV card could provide that type of
connection; you'd need to look at the PCI slot it was in and see if you
could trace one of the buses back to that unit; as unlikely as it is, it
is possible.
Then again, it's less likely that a powerspike would come in through the
main power line if it was that well protected (e.g., by the UPS).
The last time I seen something like that happen, it was a capacitor on
an 8088 motherboard. Blew itself up into shreads. *shrugs*
