5: BIOS settings

One frequently ignored cause of system slowdown is the machine’s BIOS settings. Most people accept the BIOS settings as they were configured in the factory and leave them as is. However, slowdowns may occur if the BIOS settings do not match the optimal machine configuration. Often, you can improve machine performance by researching your motherboard’s optimal BIOS settings, which may not be the same as the factory defaults.

There is no centralized database of optimal BIOS settings, but you can employ a search engine such as Google or Bing and use your motherboard name and BIOS as keywords to find the correct settings.
