So I had a HDMI cable delivered this weekend. I can now get into the BIOS every time. It was hanging on F1 with a message that the CPU fan is not detected. I have a Corsair iCUE H150i ELITE LCD Display Liquid CPU Cooler (plugged into USB 2.0 header and the CPU pump header under the CPU socket, as stated by the Corsair installation manual)

This is fine, the error does not show in boot up again, but I am still getting a hang on F1 with a message saying if the PC isn't booting into windows it could be down to system instability. I can't get into windows it just loops back to the bios when I hit F1. Swap back to the Display Port cable and I get no bios screen or see the F1 error message to press F1 to sort the issue out in the BIOS but loads to desktop once F1 is pressed.

Sorry, phone left at work with the video on so have not been able to upload it yet.
I have set the PC to Optimized Defaults, XMP off or XMP1, disabled the fan warning to Ignore and this is where I am..... very confused.
This is my memory, stated as supported on Asus website.
