Vista loading very slow

I have recently upgraded to Vista. All seems reasonable well but on loading the computer starts loading as normal then before the vista screen hangs as a black screen for around five minutes before finally loading vista. Vista then runs fine. Why is it hanging as a black screen. There is no problem after.This happens every time I load. I have a SATA hard drive which I recently fitted worked fine with old O.S)might this be a problem? Really getting fed up now so would appreciate any help.

 

Mine's exactly the same! Just one of those things I guess. Maybe a future update will sort it.

 

with vista there are lot more processes starting. when i first got mine. i had 67 running. i got it down to 52. in my XP machine i got them down to 19. but i dont think i will be able to get it down that far with vista. i wish lol
