Question: Where is the EZ Debug LED on MSI MAG B760M Mortar motherboard?

Answer:

On the MSI MAG B760M Mortar (DDR5/WiFi), the EZ Debug LED is located on the top-right edge of the motherboard, near the 24-pin ATX motherboard power connector.

Look for a vertical row of four small LEDs with labels:

CPU   (red)
DRAM  (yellow)
VGA   (white)
BOOT  (green)

Typical layout:

             CPU_FAN
                |
                |
        [ EZ DEBUG LED ]
        CPU   ●
        DRAM  ●
        VGA   ●
        BOOT  ●

24-pin ATX POWER
████████████████

On the physical board:

1. Open your case side panel.
2. Look at the right side of the RAM sticks.
3. Find the big 24-pin power connector.
4. The EZ Debug LEDs are just above the 24-pin connector, close to the motherboard edge.

For your symptom:

CPU fan spins, but no display / cannot boot

Check which LED stays lit:

• 🔴 CPU LED → CPU power cable (8-pin EPS), CPU installation, BIOS compatibility
• 🟡 DRAM LED → RAM not seated, wrong slot, memory training (wait 1–3 minutes after first boot)
• ⚪ VGA LED → GPU issue, especially relevant with your AMD MI50 experiment
• 🟢 BOOT LED → no boot device found (but BIOS should still display)

Since you are using MSI MAG B760M Mortar + AMD MI50, I would check these first:

1. Make sure the 8-pin CPU power connector (EPS12V) at the top-left of motherboard is plugged in.
2. Remove GPU and try motherboard HDMI/DP output (only if your CPU has iGPU; KF CPUs do not).
3. Reseat RAM: use A2 slot (second slot from CPU).
4. Clear CMOS.
5. Check whether the VGA EZ Debug LED stays white — MI50 is a server GPU and sometimes has PCIe/BIOS compatibility issues.

The exact EZ Debug LED area is the small 4-light column next to the 24-pin ATX connector, not the RGB/debug display area.
