I have (2) XFX 480RX in crossfire and i get different computer shutdowns when playing games, Its either this "video_tdr_failure atikmpag.sys" or says the driver has crashed and a couple of times i got an error that my video card was removed.
I replaced (2) Nvidia GTX760's which ran fine.
Games played while shutting down.
I've tried these drivers and reinstalled the cards.
Nothing is overclocked.
16 GB Memory DDR3 2400
Any help would be appreciated.
