MSI Motherboard K9AGM3-FIH Fails to Boot?

I was trying to fix my mates sound issues and thought it might be worth upgrading the BIOS. He has a K9AGM3-FIH and the sound keeps skipping when playing a file off the hard disk. I had read around that upgrading the bios might fix the problem.

I downloaded the MSI update tool and began bios flashing. Then it all went wrong. The PC stalled and then on reboot it would not switch on. The screen was black and all that happened was the sounds of fans whirring. I think I will probably avoid using the BIOS upgrade tool in the future.

I have a USB drive caddy so I took out the hard disk and backed up all the important data just in case.

After doing much reading the solution was to switch a jumper located on the motherboard which resets the bios. It took a few attempts to do this but after finally taking out the battery and putting it back in and leaving the jumper in the reset position for five minutes. All you need is a pair of pliers and some patience.

Once I replace the jumper into its normal setting and booted up, the computer POST beeped and all was well.
