Hi guys, just wanted to post my solution to being stuck at a green boot LED light with an ASUS motherboard. CPU: i9-12900ks GPU: Gigabyte Gaming OC 3080ti MOBO: Asus ROG Strix Z690-A WIFI D4 RAM: Corsair Vengeance (16 GB, 3200 MHz) PSU: Corsair RM850X BOOT DRIVE/STORAGE: Samsung SSD and M.2 Monitor: Samsung Odyssey G7 I was at the end of my new build when I got stuck at the green LED boot light on the motherboard and I couldn’t POST, even though all of my RGB (motherboard, ram, and case fans) lit up and all fans were spinning. HDMI was always plugged into GPU HDMI slot. I tried a multiple of workarounds, including ⁠Replacing the ram (tried Corsair Dominators, then switched to Corsair Vengeance), changing frequency (3600 vs 3200), changing the RAM placement (A2, A2/B2), booting with just one stick or two ⁠Unplugging and replugging everything. Checking for yanked cords or faulty power (through trial and error). ⁠Clearing CMOS with both button method and battery removal method. Also draining the remaining capacitors by holding down the power button while unplugged. ⁠Bios flashing with a USB to the most recent firmware (this probably helped, but was not obvious without being able to post) with the hopes of making the motherboard more compatible with the newer processor ⁠Switching between identical motherboards, switching monitors (between a Samsung Odyssey G7 and a generic LG monitor), switching graphics cards (between a 3080ti and 1070), switching keyboards (generic wired/Keychron K3), switching wall plugs/power strips, switching HDMI cords and placement (both on the GPU and on the monitor), trying Displayport, switching PSU cords. You get the idea, I tried almost every damn thing I could find. SOLUTION: Your build should function within the following parameters for this fix to be applicable Give power to gpu, cpu, ram, and peripherals Give power to usb devices (mouse and keyboard) Have working LED indicators (CPU, DRAM, VGA, BOOT) Monitor HDMI and POWER are plugged in correctly but no connection is being made. ⁠Turn off the pc with the power button on the case and also turn off the power to the PSU. 1A: Disconnect the monitor’s power cable from the power strip/wall plug but keep the HDMI plugged in. Keep the monitor power cable close by as you will need to plug it in quickly during step 5. ⁠Plug in your keyboard into a usb port on the back of the motherboard. ⁠Turn on THE PSU, do not turn on the whole PC. Only the mother board should light up. Your keyboard should now be powered up and connected (use number lock/caps lock to see if your keyboard is powered). THE TIMING OF THE FOLLOWING 2 STEPS IS VERY IMPORTANT 4. Turn the PC on and start mashing F2 or DEL (not backspace). Make sure your keyboard stays powered through the whole process. 5. While button mashing, observe the 4 LED indicator lights going through their normal cycle. The lights always flash in order, first the CPU light, then DRAM, VGA, and BOOT. Let CPU’s LED check-up light turn on and off (indicating there is no problem with your CPU). Then, the DRAM (orange light) will light up and disappear (if there are no problems with your ram). RIGHT AFTER THE DRAM ORANGE LIGHT TURNS OFF, PLUG IN THE MONITOR POWER CORD INTO THE OUTLET, ALL WHILE FURIOUSLY BUTTON-MASHING F2 or DEL. This should allow you bypass the weird monitor>gpu/mobo handshake and at least get to UEFI BIOS. Again, this will only help if your parts and processes are all in order and you just can’t connect to any display. Hope this helps. Answer from Smocaine69 on reddit.com
