an trying to load xp pro onto a dell gx270 sff with a 2GHz Celeron cpu, 512 meg memory, tried two different size hds, (size is not important in this case). changed out the cd roms x2, checked the cpu, cleaned the thermal paste and applied correct ampunt, changed out the cpu cooling fan. Each time I try to load xp, get to ~51% and get the message unable to load pro_seg1.swf. I have done a fresh install on 100s of other machines, but this is the first time I have seen this error message. Can anyone shed light on the problem?
