I apologise if this has already been covered, but I have searched, honest! OK, I have recently built my first pc. Mobo is an MSI 7N420 Pro, Processor is Athlon XP2500+ (Barton). On boot, the PC POST's fine, but the processor shows up as Duron 1100.... well at least, it DID, it now shows: W6363UK for test only. v1.0B1 070802 After this, IDE devices check happens, it recognises IDE as being primary, and CDRom as primary, but then flashes up "Primary IDE Channel no 80 conductor cable installed". I have checked all IDE connections and cables, swapped them over, etc, but this makes no difference. It then boots Windows 2000 splash screen and then comes up with BSOD giving the "check for viruses, remove newly installed hdd... etc" scenario I have transferred over my original HDD, which was newly loaded with Win2K, and I have read somewhere that it might be necessary to do a clean install. Sorry if this is my usual *****'s type question, but does anyone have any ideas? Thanks guys!
