Asus Windows laptop does not detect my built-in webcam

Hi Guys,
Win7 (32bit) cannot find my webcam after an update. Devce manager shows it as an unidentified device. msinfo32 shows following problems:
NAVEX15 ROOT\LEGACY_NAVEX15\0000 This device is not present, is not working properly, or does not have all its drivers installed.
Unknown Device USB\VID_0000&PID_0000\5&1C78ACB5&0&5 43

This issue started with skype not being able to detect the webcam (says being used by another program)-previously uninstalling skyp and reinstalling an older version worked. not this time
Also tried reinstalling drivers from ASUS (maybe i am not using the correct one??)

my computer model is ASUS F50SV
Any help is appreciated. Need my webcam to keep in touch with my family.

Don't pay attention to the model numbers

ASUS webcam not detected

Thanks TMagic650 but I have already tried to install these drivers. My problem is that the computer doesnot recognize the device as webcam. So windows has disabled it (code43)

Okay, you can always get an external USB camera
