It seemed like I was talking to someone who didn’t have a full grasp of the English language. I had to write like I was an 8 year old. It was global technical support.
I could take the motherboard back to the shop I bought it from but they’re super super awkward (want to test it for up to five days and charge you £20 if nothing is wrong) and the female technical support worker on the tech counter has a massive chip on her shoulder. If I didn’t use my PC for work then it wouldn’t be an issue. I guess I will stay away from Gigabyte motherboards in future.
Thanks for makling me see sense in what the problem was!
