I currently have BIOS 4005 (May 2013). There are a number of newer updates that address improved stability. While my computer is currently pretty stable, I am tempted to upgrade the BIOS to the current one - 4801 (July 2014). Is that a good idea?
Because your PC runs pretty stable right now, I don't recommend to update the BIOS, usually we will recommend to update the BIOS if the PC has problem . But if you want, and go ahead update it.
