Hi folks, I was gaming the other night in BF5 using 2 x GTX670 4gb and all of a sudden the game crashed to desktop! as it was late I just switched the PC off and never thought anything of it. The next day I started up the PC and windows 10 would not pass the startup screen on the windows logo, on every restart the windows logo would appear with the spinning circle and it would just freeze on this every time. I removed the GPU's and installed only one card at a time and tried booting and also swapped them round and still the same issue persists, if I remove all cards and use integrated graphics the PC starts fine. I removed the drivers and it still freezes on the logo screen, I have also re-installed windows 10 and this still never sorted the problem. The cards spin up as normal so I don't know if they are they dead? Anyone any ideas?
