Hi friends, first sorry for my poor English. I have a costomers MSI CX61 0NE (MS-16GB1 motherboard) and someone is badly heated by hot air station and N13P-GLR-A1 chipset is become a short circuit. I am clean all flux on the board and reball the BD82HM76 because close the heated area and i suspected solder balls get harmed.I am put 100% new N13P-GLR-A1 (GT635M) GPU and notebook works but only visible in device manager is intel 4000 graphics, nvidia is missing.I am try bios (E16GBIMS50I latest bios but i am not post the link sorry) but not help and if i try "nvflash --list" command or "nvflash -c -b backup.bin" command i get "no nvidia display adapters found" error. There no external eeprom arround and i am suspect nvidia inner rom (if it exist) is already empty or corrupt. Can anyone have gt635m vbios and help my stuation. Thanks.
