I just built a computer and installed Windows 7 ultimate onto the Samsung 850 pro 1TB ssd that I purchased to hold the OS and any important files after installing all the ms updates and drivers the computer now takes 3 mins to boot it will display the windows 7 boot animation and then once the animation finishes it will stay 'Frozen' on the screen (I say frozen meaning the screen doesn't change at the end of the animation) and 3 minutes later you will here the startup sound and the login screen will appear any suggestions on how to fix this. If you need more information don't hesitate to ask.
