I have recently noticed that Windows 7 will freeze during startup, specifically while the Windows Logo is midway from forming. After this occurs, I will usually just have to turn my computer off and then on again. When I do this, Windows will boot up normally with no errors. If I wait, the computer will automatically continue booting up after roughly 20 seconds have passed.
Originally, I suspected this may have been a driver issue with Wacom as I received an error from one of the drivers however after removing them completely the problem persisted. I also attempted to restore Windows to a time when it was function properly using Restore Points with no effect.
I have recently flashed (updated) my BIOS and installed a 2nd Nvidia GTX 680 in SLI mode. I have also recently updated my Nvidia Drivers.
What could be causing this problem?
Edit: here is where it freezes. Sorry about the quality!
