The biggest cause of No sound output with Windows 7 & Vista, that I have found, is the simple error of setting the default output device incorrectly.
Most, if not all, modern motherboards, will have both analogue and Digital output capability. This will be picked up as present by the driver even if no actual connections have been made.
Windows also sometimes gets things wrong when selecting the default output to use
It may be worthwhile checking your defaults, John. Right Click on the speaker select Playback devices, and check which has the Green tick, It does sound obvious but I know it can be easy to miss I wasted over an hour on a Vista system not long ago
