Windows 8 computer takes about 3 minutes to boot up

Hey guys, this is my first post here so bear with me. I would first like to say that I am in no way a novice computer user. That being said, I've been having problems with how long my computer takes to boot up. When I first got it the boot time was around 20-25 seconds, but now it takes almost a full 3 minutes. And I have OCD so I make sure my computer is pretty much kept up to date and clean. I regularly do a junk files clean up once every 2 or 3 days, the hard drive always has a fragmentation value under 2%, I use Revo Uninstaller to uninstall all my apps and remove leftover files, and all my programs and drivers are always up to date. All that being said though, I still have a really long boot time. So my question is, how do I decrease my boot time to when I first got my computer. I would like to avoid reformatting the hard drive if possible. Thanks!
