    I know this subject has been thoroughly covered but I am at a loss...
    I have done everything the forums, this one and others, say about installing the drivers so that the Fn, S1, S2, eject buttons on my z540 work.
    I installed win 7 home premiuim 64-bit and followed the instructions and everything worked perfectly until a couple of weeks ago.
    I haven't installed anything new. The only software installed have been the updates the Windows and Sony recommend.
    Please help!
    Thanks.
