Hi guyz.

Really need your help.

I have a laptop Compaq Presario F731AU running with Windows 7.

My problem is the OS suddenly cannot detect my audio hardware n like it gone.
I already update my BIOS with current version.

Go here Microsoft Update Catalog and download the appropriate driver. Top one is for x86 (32bit) Windows 7 / Vista, next one (second in list) is for AMD64 (64bit) Windows 7 / Vista. See if that does the trick.
Good Luck
