I just bought a VisionTek RX 470, replacing the GTX 745 that was in the pc. My issue is, I just installed it, hooked it up, and plugged the gpu in with an HDMI cable, and no signal. So, I used the default HDMI to see if there was anything I could do from there. I was able to see the screen, and navigated to the windows 10 login. As I was logging in, the pc bluescreened and gave me the error KERNEL_SECURITY_CHECK_FAILIURE. Any help would be greatly appreciated.
NOTE: I had gotten the KERNEL_SECURITY_CHECK_FAILIURE error before, usually a restart fixed it, not so much now.
UPDATE: I have checked the 6-pin connector, and re-seated the gpu, now it displays the screen but still has the error, I tried to use safe mode to install drivers, no luck. I tried safe mode with networking and I could not enable to wifi. Without the ability to plug into my router (too far away) I still haven't found a fix.
