Win 7 Splash Screen Freeze

I have updated to the latest BIOS on my computer.... Win 7 still seemed to load just fine after the update. I then loaded the default settings on the BIOS and this seemed to have been the cause of my Win 7 now freezing on the splash screen. I have tried placing the BIOS settings back the way they were, using last known good, starting in safe mode, and startup repair with no luck. The safe mode and startup repair options do not fully load as well. Not sure what else to try to revive this system. Any ideas? Thanks!

Go into the BIOS and check and see if:
Boot order is correct.
AHCI setting is correct.
Video display options are correct.

I do not know what "correct" is for your machine, but this is where I would look. In particular, make sure AHCI is not set to "compatability" as your hard drive is SATA.

Try these things and let us know.

Re-flashing to the prior BIOS might work (but use much caution because it might not).

Can you start from a Bootable CD?  Try this and let us know.
