I had the same issue although only happened once thus far. Had the card since Sunday and been on lates this week so not spent more than 2 hours gaming. With the Coil Whine its a disapointment, I usually have excellent PC Components Karma.
I've waited approx 15 months to buy a new GPU and this felt like the right purchase
Gonna try some older drivers, if it helps I'll post any solutions I find.
Thanks
