|Driver updates are not going to have any effect on the BIOS or its settings.|
You should ONLY get your drivers manually from the system manufacturer's website on manufactured systems and from component manufacturer's sites for custom built machines and for upgraded components that did not come with the machine originally. NEVER let any program or site choose your drivers for you. I do not even let Windows Update update my graphics driver, if it shows one is available, I go right to NVidia and get it from the source.
Reboot your system into Safe Mode with Networking (uses minimal Windows drivers for needed hardware only in safe mode) and download the correct drivers and install them. Then go to device manager and look for any device with a yellow or red warning. If there are and you are sure that you just installed the correct driver for it, right click on it and delete it. Then restart the machine in normal mode. Windows will reinstall the device with the correct driver you just downloaded.
Your title refers to not detecting hard drives which will not be effected by any drivers except possibly chipset drivers for your motherboard and drivers for add-on SATA cards (these may not be seen until your OS is loaded, depending on the card and your motherboard). Hard drives that are connected to your motherboard directly should always be detected in your BIOS unless 1- The drive is bad, 2- The power or signal cables are bad or disconnected. 3- You have a problem with your power supply, 4- You have a major problem with your motherboard's hard drive controller. The first thing you should do then, is to try swapping out the hard drive signal cable and try another power connector from your power supply. Next would be to try the drive as a second drive on another desktop computer.
You have to be a little bit crazy to keep you from going insane.
