Hi!
First of all I would like to thank everyone! This made it possible for me to mod my Maximus IX Apex myself.
At first, everything seemd to be fine but unfortunately it came to a problem.
I've installed the i7-9700k (R0 stepping) and flashed the BIOS from dsanke (ROG-MAXIMUS-IX-APEX-ASUS-2402) (great job dsanke!).
System started and booted to bios ( yay )
So I decided to install my gpu (asus rog gtx1080), closed the case and wanted to proceed with os installation.
At this point, the board is not starting anymore . The aura leds are on, but if I press the start button (board or case), I noticed that the system wants to start up for about 200ms. I barely see the flashing LED from my Corsair AIO (H100i Pro).
My first thought was, that something is wrong with my soldering.
I've resoldered the mod (bios & cpu pad) on the motherboard and flashed the BIOS again. No improvement.
So I decided to remove the cpu pad mod, install the i7-7700k and flash the original BIOS (1302).
Same problem as I mentioned before. Aura leds are on, system is unable to start.
I also installed the speaker. Status leds are off (cpu, ram etc.) and no codes are shown at the 7 segment display.
My assumption is that something is shorted or even broken.
I've no idea where I should start to search for the problem. Maybe somebody has some tips or ideas that could help me. Thanks a lot in advance.
