Hi Andy,

Is it possible that you have a Logitech wireless keyboard in your system? I bought the same motherboard that you have (Gigabyte GA-P35-DS3L) and I have the same problem with the video card (that motherboard will do analog and digital audio out at the same time, btw). I was reading on the NVidia site, and they said a similar problem could occur if you have a Logitech camera installed, but I don't have one. I am using the Logitech DiNovo keyboard, though, and I'll try removing it from the system tonight.

I can't believe that there is simply no end to this. I have replaced everything except the RAM, the processor and the drive. I believe more and more that this is a video driver problem.
