Do you really need to update your BIOS? If everything is working just fine, then don't bother. Is there some feature that the new BIOS unlocks? Or improves stability whilst overclocking?
I have never updated a BIOS in my life and my dad put the scares on me about them a few years back so i never thought any more about it.
However, is it a deadly art or do ytou just have to be careful?
