Other than the obvious new feature, I can't say as I've noticed any difference with 1005 from the previous - no stability issues or noticeable performance changes. I didn't have any problems to resolve either, so no change there.

I've no idea why you're having problems with 1004c. If things are already bad on your system, what harm can the upgrade do? However, I'd expect it to be driver or windoze related rather than to do with the bios.
