He uses XP, I was looking through the stuff for it and I found a sheet saying that no CDs came with the computer because they were already pre-installed, we got it in some deal with my mums work (Renfrewshire council) years ago, if that makes any difference. I'm having a problem just now, I made a clean installation of the OS, but the network adapter isn't installed and I can't find anything in the CDs... some guy fixed it a few years back and he properly screwed around but it worked up until a few nights ago. Any ideas?
