Hi,

last Friday the Videocard  (AMD Radeon HD 7970M) died. So i Bought a new one (HD8970M). Wednesday it arrieved. i installed it. Installed newest AMD driver. seems to Work. So I started Playing some WoW. After an half Hour I recognized that its getting really hot because the GPU Fan didn't move. Tried new BIOS (A12) other Driver. Unistalled all Drives via Display driver Uninstaller. than i found that with HWInfo I can Set Fans Manual (works well). But now there is no way i get the Graphiccard working again.
in BIOS it says "Discrete Graphic: Not detected". I removed the GPU and reinstalled it. bootet -> BIOS says "discrete Graphic: ATI GFX" -> reboot to Windows -> no Graphic card in System manager (except Intelhd4000) AMD driver says: no AMD installed. Reboot -> bios -> "Discrete Graphic: Not detected". Retried all of this with no AMD driver installed. in Systemmanager there is "Standard-VGA-device) -> installed driver -> no graphic driver installed.
(tried another BIOS A11) same issues

 

Please are there some hints? i would try the Unlocked BIOS but i can't download it right now because of Pre-Promotion
