In a Fractal Design Meshify S2 Case - I've plugged the fans into the controller, and the controller into the SATA power and the CPU_FAN jumper
Known-good KB/mouse/display (2560x1440 dell)
Installed everything as per the various manuals, AFAIK.
First (and all subsequent) boot posted "02"
Things I've tried:
Reseated CPU (and checked Pins - couldn't see any damage) - I don't have an alternative as I'm coming from Intel Reseated GPU Reseated Memory and tried both DIMs individually in slot A1 Tried a known-good old GPU (which is back in my old PC and in use as I type this) Tried two of the three available PCIe slots (my card won't fit in the outermost one) - I've not tried the "alternative" mounting position. I've tried slow-boot, checked the LN2 jumper (and tried with it set and unset), and everything else that looks like it's configurable. I've tried using both the HDMI and DP ports on the graphics cards with known-good cables (into DP mini/HDMI2 in case that's relevant). I don't have anything plugged into SATA on the MB (the case is plugged into SATA on the PSU though - needed for the fans, AFAIK) (Per the above, the drive is 1TB M.2)
Current (and persistent) symptoms:
Will do the initial post for a while, displaying "ROG" etc., and "press f2/del for BIOS". It will hang at that screen, asking for me to press f1 to setup.
In case it's useful - the PC is unresponsive after the "02" appears; caps-lock/num-lock etc, do not change lights on the keyboard and no buttons I press have any effect that I've seen, including ctrl-alt-del.
I think it's now fixed (got a call from a friend who heard I needed help) - turns out it was the wireless keyboard (though when I started I used a wired one, with the same effect, but before the BIOS upgrade I think)
Note that the wireless mouse is not, and was not, a problem 😕
