So, after finally taking the plunge and buying a 1070 I cannot for the life of me get it to be recognised by my PC. I'm not the most PC savvy person but I like to think I have an idea of what I am doing. Anyway, the card is on and powered, blowing amazing amounts of cold air out but it is not detected at all in the BIOS or device manager. I've reseated my RAM, tried different PCIE slots, changed the settings in my BIOS referring to PCIE X16 speed (Gen 3) and the primary driver (Changing it to PCIE). I've had problems with 2 faulty GTX 970s which were determined to be DOA by the retailer and I thought upgrading to a more modern card would help things be simpler. Any advice is appreciated as I don't have any other rig to test it and I live hours away from the store that I bought it from. Thank you
