If the date and time is configured properly in the BIOS, and you've tried booting to BIOS safe or default settings, then resetting the BIOS is actually the only other method you can try to reset this. The problem isn't necessarily Windows, although it did change the data, but the BIOS. Set the "Reset ESCD Configuration Data" option (if your BIOS has one) to Enabled to force an ESCD reset, and re-detection of plug and play devices. Shut down, and remove all USB devices other than keyboard and any PCI or AGP devices installed in your system unnecessary to boot other than the video card, and then power back up. This should get you booted again, and once you're up and running you can shut down and add your devices back (one or a few at a time) to see if any of them cause an issue.
