samsung NP359V5C bios downgrade

[jokker80]

hi y`all. i have a Samsung NP350V5C laptop and i`ve upgraded it`s bios with samsung`s latest bios version. Iam using Windows 7 professional X64. After bios upgrade, i have no sound. in device manager only the HD audio display driver. realtek driver is missing. and after i scan for hardware changes, the sound card is not visible. i only have audio thru HDMI cable. internal speakers are not working, audio jack and mic are not working. taskbar volume icon is marked with red X, and it says `` no audio output device is installed``. SO.. in conclusion.. after bios upgrade.. the motherboard does not recognize the sound card. my question is... how on earth can i downgrade the bios.. cause samsung`s bios updater doesn`t let me.. is telling me that the sistem bios version is newer than the update available.. Thanks in advance..
