vista boot problem

[blazer]

when vista is booting up, i get to the welcome screen but just when it should show my desktop the screen goes blank. the hd light flashes like mad and vista will never fully boot up. if i reset it several times, i will eventually get my desktop and everything runs ok from then on. anyone have an idea of where i should start looking for the problem?

Did your version of Vista come with SP1 or did you have to download it? I don't remember the exact sequence, but when I installed Vista, I immediately got into the process of installing about 80 updates (in May of this year), and in the middle of that (the 80updates), SP1. Since then many more updates. No real problems. Hope you have it fixed by now! zburns
