Any chance you could clarify where I stand on the following problem. I have a gigabyte g1 sniper m3 motherboard which when tested with 3 different gpus, did not display anything on the monitor in either of the x16 or x8 pci-e slots. It was purchased from amazon on the 29/09/12 but with unknown warranty. As a motherboard and working gpu are fairly essential to a computer I have replaced the motherboard but still have it. How would I go about returning, replacing or exchanging it and can it be done within warranty or statutory rights and if so, do I have to rebuild my pc to prove it is faulty? Cheers!
