The Windows MD5SUMMER
. Run that to compare the MD5SUMs. Once you get Linux installed, you can just "md5sum <whatever_iso>". In another post you mentioned that you have a Radeon 9600. The installer may be balking on that, as ATI is a bit slow supporting linux (should I say letting someone else look at the specs so THEY can make a proper linux driver). Embarassed they are a Canadian company. You might want to check your ram as well. In another thread, you said you have tried som live-cds. By any chance, had any of them had memtest86
on them? If not, you could download it and save it to a "system" floppy (make one with the floppy formatter) and run that for an hour or so. See if there are any errors. If so, chuck your ram and buy new.
Or, you could go back to what came with your machine....we hope you tough it out. Your experience will help those who come after you
