Go to your hardware manufacturer’s official website >>

Once there download the latest drivers >>

 (IDE ATA/SATA are drivers which can cause this kind of problem. So, install the latest version.)

If you want to update drivers automatically then go to Auslogics Driver Updater. No need to take the hassle of having to find the best drivers for your computer. It does the work for you. This is faster than if you do it manually.
