Windows 7 Startup Delay Before Login Screen

I just reinstalled Windows 7/64 Home Premium and all of the software I need on my ASUS A53E laptop (Pentium 2.2 GHz, 8 GB RAM). I am not sure when it happened as I had several reboots that had to be done while installing my software and the Windows updates and I was multitasking with other things and I did not watch each boot-up, I would come back to my laptop with the Logon screen showing... but now I see that after the 'Starting Windows' screen when the animation of the Windows icon/logo finishes, I have a long period (about 45 seconds or so, I haven't timed it) where the screen is black with an active mouse icon and that's it... after the delay it goes to the Login Screen and starts fine after I enter my password. I have Bitdefender Internet Security 2015 and it has a few optimization tools with it and I've tried them but nothing helps. I have defragmented the hard drive, checked for errors via Windows tools and nothing helps. Ideas on how to fix this or a startup tool that can find out what's going on? Thanks!

seems relatively normal, some computers tend to do that, just a normal part of booting up sometimes. 45 seconds seems pretty normal legnth for this sort of pause.
