I think you only have one SATA controller with 4 ports. You can't change them anyway because you have a RAID setup. That driver won't install because it's the wrong one, you can delete the one with the yellow asterisk. I also think that the current driver is the latest - 220.127.116.11? Have a look to see if the driver provider of AMDk8.sys is Microsoft or AMD, it's listed on the driver tab page. I only uninstalled mine recently and it's now using the Windows driver - processr.sys. The i8042prt.sys file is a PS/2 driver (mouse & keyboard), looks like the USB isn't the problem. Also, see if Everest will tell you what your motherboard's make and model is - motherboard>motherboard.
