I've bypassed that, by actually doing a fresh install of XP. Yes I now suspect that some kind of hardware problem may exist. Its always freezing when installing the Windows service packs & graphics driver. The computer is extremely dusty inside (could that be a problem?) and how would I best clean it without damaging anything? On unplugging, do you just yank it out, blow it replug, or is it much more complex (yes I am a noob) Any suggestions on resolving the graphics driver problem?
