did u try to clear cmos? the bios is error loop during self-check. temperature on ur mb seemed normal so far.
can remove or change something for further check? remove your wireless kb and ms firstly .. and if insert memory one by one in different slots ..
I tried boot the computer where I put the motherboard on an anti-static mat with only the cpu and it's heatsink and one stick of RAM connected (no peripherals) and I still got the same symptoms.
I did try a clear CMOS before updating the BIOS, and after, following step by step the Gigabyte motherboard sticky with no effect.
How can the BIOS error loop in the same exact way when I installed a new version of it though?
