2, make sure the system starts correctly without rx480
3. turn off the system, insert "dead" rx480, connect 1 and 8 pins on its bios somehow (soldering, paperclip or whatever, I used a paperclip), power on
4. if the system turns on, go to windows or dos, disconnect 1 and 8 pins on rx480 bios, check if "atiflash -i" sees the card then reflash it with proper bios file. Otherwise check if 1 and 8 are properly connected at startup.
