Asus GeForce GTX 1070 STRIX OC
It starts off by turning the LED's to purple. After that the fans stop, it starts flashing red and i have no control over it at bios. Can someone tell me what is wrong and how do i fix it. i have tried to control the fans via MSI Afterburner and GPU Tweak II. How can i test if it is the PSU or the Motherboard that causes these problems. i do have an old AMD GPU that only requires the fans to be plugged in but it will take 4h to disassemble and assemble the old PC. I had gtx 1070 before but it broke when i was using it with this PC.
