I had the same problem with my VAIO VGNA217M.
After hours of looking for solutions inspried from another querie about keyboard problems I
went to UTILITIES. I coubleclicked the exe. and after some minutes everything was ok again.
If you dont have this program on your computer you should download "preinstalled utilites" from the VAIO update page.
Good luck.
Have you installed anything recently?
I had a similar problem once which I think was down to conflicting programs.
Samer,
This stops because you might have Demon Tools on the VAIO
