Hm, I dont have that MOBO but my best suggestion would be to update the bios/firmware.
If that doesnt work then I would clear the CMOS (before updating the bios) (be sure to back up any important data on your HD as well before you do this, It's recommended to do this after flashing the hard drive)
Here's a video on how to reset the CMOS manually on your MOBO
Topic: Asus Z270-A Mobo - Can't get into BIOS (Read 113 times)
I know a lot of miners use this very nice Asus Z270-A motherboard as it can support up to 8 GPU's. So, I am hoping that somewhat has experienced the same problem I am having with not being able to enter the BIOS to enable support for more than 4 GPUs.
I built a rig with this Mobo a few weeks ago... currently running 2 1070ti's and 2 1080's... Windows 10 Pro with 8GB RAM like my other rigs. It has been mining various coins perfectly since that time.
However, I finally got a chance to go in and modify the BIOS so I can add the 2 more 1070ti's I have to it... and for some reason, I cannot get into the bios. I tried it many times, each time tapping or pressing the Del key or F2 upon start-up, but nothing.
The weird thing is that the Asus splash screen never even appears upon rebooting. Screen goes dark (as normal) but then after that, I get a weird message from my monitor 1) no signal detected, the 2) monitor going to sleep... shortly followed by the windows login screen appearing within a few seconds. I tried tapping F2 and Del at all times during this few second process but it will not enter the BIOS.
Something else that may or may not be related... for whatever reason, there are a few basic functions that have never worked on this rig. 1- Left-click functionality does not work on either the power options button or in the windows search bar at bottom left of screen. I actually have to right click on the power button then choose reboot that way. 2- left click doesn't work on some launch items in the task bar (like IE), but it does work on the File Folder icon.
FWIW, I have the monitor plugged into the GPU that is plugged into the first PCIE x1 slot (closet to the CPU) via the DVI to HDMI cable that came with my monitor. Since this and the other 3 GPUs work perfectly for mining, i don;t believe there is any issue with risers, etc. I read in some Asus forums that monitors needs to be plugged into GPU slot #1, which IMO, mine is.
But, is it possible that by #1 slot they mean the first x16 slot and not the actual first physical slot, which is an x1?
Anyway, any suggestions would be much appreciated. This is probably an easy fix that will make me feel stupid but i just want to get those 2 extra 70ti's mining lol.
