I'm on Vista Ultimate 64 bit just so everyone knows. I have this small problem that I get every now and then randomly, when my computer is booting up sometimes it would sort of reset and start the boot process all over again, then I would have to choose how to start up windows and usually the option that says something like 'Last known successful configuration' is the one that works, not always, but most of the time. Also, sometimes it takes up to five or so tries to get it to boot up. I dunno why this happens or when it happens, it's just random from what I've noticed. Is it from drivers? I know it's not from spyware or anything because it happened right when I reformatted and reinstalled drivers once.
