Packard Bell Easynote MX65 Drivers

Hi

I am battling to find the drivers for my Packard Bell Easynote MX65. I had to format the hard drive and re-load Windows. I am having a majour problem trying to source the drivers, my sound comes out the speakers but not out the audio jack. The webcam doesn't even register as existing no matter what drivers I try download for it. Also the bluetooth and network drivers are missing. Please help!
