Hi! I have a Radeon R9 280X Vapor-X that I had prestanda issues with. I upgraded the BIOS for the graphic card to the latest version and after that I only have a black screen when starting the computer. My plan was to take back the old BIOS-version (I saved the file) but I can't start the computer with the card mounted. I have changed the computers BIOS so the internal graphic card is used. Everything works fine if the R9 not is mounted, i e picture on the screen from the internal graphic card. If I start up the computer with the same setting (internal card) and have the R9 mounted I get the error: SYSTEM_SERVICE_EXCEPTION.
Anyone that can help me with info so I can downgrade to the old BIOS-version..?
Thanks in advance!
