I`m having pobs with my daughters pc. it has the same components as mine. Athlon 2400+ cpu & 750Mg ram. But is very slow to startup.Get Windows bar then black screen and wait about 4 minutes before welcome screen, Mine loads in 10 secs. Once running it`s fine. Using Trend PCcillin virus prog.But still takes time if Tend disabled. Just completed optimization of temp internet files and unused registry files but still the same. Any ideas please.
