Subject to the house wiring being modern and correct your PC chassis is
probably grounded, your TV being only a 2 prong plug probably not.
If you brush against the screen when on or even more when recently
turned off you will feel the hairs on your arm stand up due to the
static produced by the TV. It is possible that a build up of static (It
can last for hours even with the TV off) discharged via the graphics
card connector and took out some chip or other.
Same problem her hand caused a spark, probably wearing plastic soled
shoes, dry atmosphere, synthetic car seats, wool sweater. 30,000 Volts
when she got back out the car. S'why there's a sign up saying touch the
car body AWAY from the gas filler if you get in and out while fuelling.

If you try again I suggest you touch both the computer case and any
metal connectors you can on the TV connector before making the
connection. Always best not to walk on synthetic carpet etc when working
on electronics.
