The latest BIOS update for your PC would be for Vista ((1.16 Rev. A (11 Oct 2011). I doubt that updating the BIOS will resolve the issue you are having. None of the BIOS release notes for any of the BIOS updates address a fix for any issue related to what you are experiencing. It sounds like more of a flaky memory chip issue to me.
