I did a bios flash on my strix z270e gaming from version 1302 to 1501 which seemed to go as expected. Unfortunately it then wouldnt boot into the bios or windows. No screen with the debug LEDs alternating between orange for dram and red for cpu. After a bit of debugging i am now back to bios version 1302 with a single ram stick installed. I am now at a point at which, after removing the cmos battery for a couple of seconds, i am able to boot into the bios and from there into windows. But as soon as i restart the same issue persists until i remove the cmos battery once more.
I have re-flashed the bios with freshly downloaded files as well as removing the GPU entirely and running off the integrated gpu but observed no change in the behavior. Any advice is welcome, even if its just to scrap the mainboard
