Scratch all that - chap sent me through a Dell Optiplex Resource + Driver disc
So now I installed the LAN port driver (which works) and the Intel Graphics Driver (which has made my screen scroll speed faster and smoother, tho it is almost like the text is a little blurred when still, like then typing this. Not blured as such, almost like when you have tired eyes and it's a little out of focus)
Didn't bother installing the on board sound driver since I have fitted my digital sound card - I wasn't sure if they would conflict? Sure someone told me when you fit a PCi soundcard to a machine with on-board sound that you have to turn the on-board sound off in the BIOS anyway?
