Thanks icelock I'll keep that in mind.
Used "last known good config" when booting, so far so good, although when clicking the start menu>all programs>any folder the default file icons(the little paper with tucked in corner) linger for about 10 seconds before loading the image icons appropriate to the programs. Usually this isn't a big deal, but on a fresh boot with no programs running, they shouldn't linger at all.
Maybe I'm just being paranoid but that's a sign of a slow/dying hdd right? All other programs work fine for now, although the "last known good config" reset all my program licenses and drivers. But we'll see in about an hour if it starts to hang bad again.
Thanks for the replies.
