Hi there.
Thank you for the reply, I know my rights under the sales of goods act and I am willing to go through the process and argue that the goods are not "of satisfactory quality"
The motherboard I have (ga-p31-ds3l) has a problem where the on board network card has broken, the operating system can still see it but I can't connect to the internet. Looking online I am not the first person who has had this problem with the network chip, which is installed on this and many other Gigabyte boards.
So its safe to say that its also not fit for purpose, I would take this up with the retailer but as they are not around I have to take it up with Gigabyte. I still have six months left of warranty if (like normal retailers) you would go by the date of purchase.
I have two of these P31 boards, a P35-ds3l and a Z77 from Gigabyte, but I don't think that I will make another purchase from this company again. Staff here on the forums should have contact details for the relevant department at Gigabyte UK. It would be a great help if you could forward the details to me via private message.
