VAIO SZ1XP/C and Windows 7 issues

I have a VAIO VGN-SZ1XP/C that I have recently upgraded to Windows 7. The update itself went OK but left me with several issues around the Sony features (rather than other applications) . The most annoying are:
- the webcam is not recognised. I think it it seen by Win7 as an "unknown device". Is there a driver that I can try to point it at to get it to work/be recognised?
- the touchpad works but the scroll areas at the side and top do not work. Again, is there a driver that I update to that will add on these features?
- the Bluetooth is on (ie the blue light is on) but nothing works. Either I need to find a BT driver or a way to turn it off as it is eating the battery. Any ideas?
- the Function keys, the 'S' keys and the Stamina/Speed key all don't work. Any suggestions to get control of them back?

Thanks for any help that might be out there.

 

for me the best way it's clean install not upgrade,there are plenty instructions to install w7 on vaio sz,try using search button

 

Re the comment above, it was a "clean install" of Windows 7 - so I have upgraded the Vaio.....

I have got the touchpad, and fingerprint reader working OK. Plus I seem to have updated the NVidia drivers.

BUT I still cannot get any contact with Bluetooth or the webcam. I think it sees the webcam as "unkown" but I can't find a driver that will work. I have tried the Sony site with drivers for this machine and Vista but no joy. Any ideas from anyone?

 

Finally found the webcam driver in SODCAM-01074405-US.EXE on the Sony site and it works.

Still can't solve the bluetooth problem - all suggestions welcomed
