How do I update the BIOS on my Gigabyte motherboard?

I have a Gigybyte K8nspro. I went to Gigabyte's website and downloaded the BIOS. On my desktop, there are three icons: Autoexec (MS dos batch file), flash895 (application file), and k8nsp.14c (14C file).

When I double click on autoexec or Flash895, it takes me to some strange screen. On top it says "Flash Utility".

I'm not familiar with this so I exited without doing anything. I just didn't want to mess anything up.

What can I do at this point?
