Long loading screen before Windows load screen

[B33FReaper]

Hi, I have a computer I have built and upgraded several times for my step-son. The issue I am having is after startup or a reboot the computer goes through post and then I get a blank screen for 10-15 seconds. Then I get a serrated white load bar that runs the length of the screen at the bottom it takes about 3-5 minutes to load. Then I get the Windows load screen which takes about 10-15 seconds and then I get the account icons and everything is fine. I am not sure what this white load bar is from and it is really slowing down the boot times. The computer has gone through an upgrade and the issue still persists, which I expected. I upgraded the motherboard, processor, and video card. Any ideas on what the cause/fix for this extra loading is would be appreciated.

Did you do a clean install of Windows after upgrading the mobo? If not that could be your problem
