And I repeat what I said, if your system does all that you want it to do there is no need to update the bios.
You are correct that BIOS updates do sometimes do those things you listed. Please do use EZFlash2 via the tools section of your bios to flash and let your system do the full process even if it seems to be taking a long time. The reason I am not so keen to have people just flash bios is because of the risk involved. There is always a risk, a very real risk that you can end up with a borked motherboard.
To help us help you - please provide as much information about your system and the problem as possible.
