I was just curious how many people that are having this problem don't have their system (PSU atleast) hooked up to a Uninterruptable Power Supply that has a built in Line conditioner.
I had to get one for my system because there is so much line noise in the wiring of this old house. On top of the fact I live in SoCal, suprising we haven't had any power outages this summer so far.
I also got it because it insures that my system is getting maximum power it requires.
Hope they figure out what's wrong with you cards... that does suck.
