Re: Keeps trying to update FW. Done - reboots and does the same again.
The first thing to try to do would be remove all power from the system, and let it sit for a few minutes. Once all power has drained, try rebooting again. If this doesn't work, remove all power again, but this time, reset the CMOS. If you reset the CMOS, if you are using any custom settings in your BIOS, you will need to change those again.
