As always impeccable delivery amazon ... After 5 years of loyal service from my HD 5870 Vapor-X amd, I decided to change maps. I uninstalled all drivers amd, updated my bios (motherboard asus maximus extreme-z) and Windows 7 (x64), I installed the new card and the latest driver nvidia but windows reboot disables the card Windows message has stopped this device because it has reported problems. (Code 43). I spent almost a whole we to seek a solution and try all the suggestions found no success. I tried on a windows machine 8 and still the same problem - card disabled by windows 8 I installed windows 10 preview and ... same result. I had to resign myself and think that the card was defective. I could not check the right notes on this card because it did not work for me. Blame it on bad luck? Map obviously returned.
