I haven't changed anything that I can recall, but my boot has taken forever since yesterday. I'm sure I waited about 5 minutes for it. The first time it happened, check disk popped up after a while. it said everything was fine. After a small pause, it took me to my login screen. When I turned on my computer this morning, it also took around 5 minutes. The loading bar paused for about 5 seconds somewhere in there, but then it continues right where it left off. After maybe 30 seconds, the screen goes blank but my monitor doesn't go into sleep mode. After 15 seconds or so, I got to the login screen. Has anyone seen this before?
