Troubleshooting

System does not power on

Verify the 24-pin ATX and 8-pin CPU power cables are securely connected. Check the power supply switch and the case's power button connection. Ensure the PSU is functional.

No display output

Confirm the monitor is connected to the graphics card (if installed) or the motherboard's display output. Reseat the graphics card and RAM modules. Try booting with only one RAM stick.

RAM not recognized or unstable

Ensure RAM modules are correctly seated in the DIMM slots according to the dual-channel configuration. Check the motherboard's Qualified Vendor List (QVL) for compatible RAM. Try updating the BIOS.

M.2 SSD not detected

Verify the M.2 SSD is correctly installed and secured. Ensure the correct M.2 slot is being used (check manual for PCIe 4.0 vs 3.0 priority). Some SATA ports may be disabled when an M.2 slot is in use; consult the manual.

Overheating or high fan speeds

Use Fan Xpert 2+ or UEFI BIOS to adjust fan curves. Ensure adequate case airflow and check for obstructions. Clean dust from heatsinks and fans.

USB devices not working

Check that USB devices are connected to the correct ports. Reinstall USB drivers from the ASUS support website. Try a different USB device to rule out device failure.
