Know this is the UK forum and I am in the US, but  I  could not find an Official US forum.
Anyways.
December 22,  I send the motherboard(1 year old) for the first RMA due to a POST error code of 1 long beep  3  short, indicating bad RAM or video.
I get it in reasonable time in mid January 
Boot it up, same POST error code, tried different RAM, same error code, tried a different graphics card, same error code (Al RAM/graphics card works  in other PCs)
So I contact them back,  they said they will pay shipping back to their  place, took a long time for me to get the label
I get it back, sold it to someone. The same day they  got it, they emailed me and had the same exact POST error  code.
So I take it to a local PC shop to see if they can help me isolate the problem, and they tell me a  bad PCIE slot was  causing the POST codes.
So I sent Gigabyte an email, no response  at  all.
Send another, they tell me to call tech support, who I called, was on hold for 5 minutes, and then sent to voice mail.
I called again,  and they  couldn't help me.
So I email CS yet again, no response. Post on  the Facebook page, no  response, yet all "good" comments had responses within hours.
So I file a complaint to the BBB, 6 days after they received the complaint they finally respond telling me to call or email  some guy.
I email him,
3 days today no  response, 
And what kills me the most is I was told and I quote 
The replacements were fully tested prior to shipping by our engineers. 
If that is the case,  when I sent my first RMA out, the engineers should of failed the motherboard to being shipped,as they accepted the second motherboard.
