These two 5970s quit their jobs and don't want to mine anymore. It's a little odd that they are the only two problematic 5970s I have and their symptoms are almost identical: in Windows you can perform most common tasks with them including browsing Internet and watching youtube, but if you watch 3D movie, Windows driver keeps recovering from crashes.
In both Windows and Linux, running Bitcoin mining program will cause system crash.
I've replaced their fans with brand new ones, and re-applied thermal paste, which is pretty much what I am comfortable doing with these cards, it didn't help. So I am auctioning them off, if you are good at fixing cards, this can be your opportunity.
Starting bid is 500 LTC, US shipping cost and insurance should be included in the bid price. PM me for international shipping rate.
Auction will end after 24 hours without no new bid. Auction will end 04:00am August 21, 2012. GMT.
Have fun.
Edit: Changed this to a 3-day auction because I don't want it drags too long.
Edit: Tried to run Furmark, burn-in test won't run; gpu-z and gpu shark can show information properly
