![]() ![]() Remove your GPU to verify that the card's PCB is un-damaged and that all contacts are clean on the board.If other storage devices do work, this would indicate a defect in the storage you were previously attempting to use.įor a VGA debug LED, please try the following: Find a different SATA storage device to test if other devices work with the motherboard.Switch to different SATA ports on the motherboard to verify if a particular port is not functioning properly.Use a different SATA data and SATA power cable to rule out any defective connections.Please verify that both the SATA data and SATA power cables are connected to your storage device.If one SSD works in both slots but the other works in no slots, this indicates that one of the M.2 SSDs could be defective.įor SATA based storage from SSDs and HDDs, try the following: If you have two M.2 SSDs and you are getting a BOOT LED, attempt to also try using one M.2 SSD at a time in both slots. Try switching the M.2 SSD to the other open slot on the board, if this fixes the issue, then please let our Customer Service Team know.Remove the M.2 SSD from the slot to verify the M.2 contacts and the M.2 slot are un-damaged.M.2 SATA SSDs (B-Key) are not compatible with the N7 Z490. Verify that the SSD being used is an M.2 NVMe SSD (M-Key).If a particular DRAM slot is not working correctly, please get in touch with our Customer Service Team for assistance if a specific RAM stick prevents the POST, that likely indicates a defect in the RAM.įor a Boot debug LED, the troubleshooting will depend on the type of storage you are using with your system. Test your RAM one at a time in each slot on the motherboard.Do not mix and match RAM that is not the same model. Verify that all the RAM are matching models.Your dual sticks of RAM should be installed to A2 and B2. Starting from the leftmost slot, the slots are A1, A2, B1, and B2. Double-check that any dual-channel RAM is installed to the correct slots.We recommend installing the RAM with the motherboard lying flat on its back. Ensure that when the RAM is inserted, it is seated evenly in the DRAM slots.Then verify the DRAM slots on the motherboard are not bent or coming off of the motherboard. Please remove the RAM and verify that there are no burn marks or chips on the PCB.Double-check that the CPU power from the PSU is connected properly.įor a DRAM debug LED, please try the following:.Check that the processor is compatible with the N7 Z490 (10th Gen and 11th Gen Intel CPUs only.).Next, verify that the CPU is installed correctly with the gold triangle on the CPU pointing to the bottom left of the socket.Damaged Pins and Contacts can look something like this: First, remove your CPU to verify that the CPU contacts and the socket pins are undamaged.If you are encountering a CPU debug LED, please try the following: Please reach out to our customer service team for assistance. NOTE: If you have an NZXT Prebuilt or Custom Gaming PC, skip the instructions here for the CPU debug LED. If you are still having problems after clearing the CMOS, please refer to the following troubleshooting steps correlating to the debug LED lit up on your motherboard. Wait 30 seconds to ensure no residual power in the PC, then press and hold the Clear CMOS button for 3 seconds. The Clear CMOS button is located on the rear I/O and can revert BIOS settings to default.Ĭlear CMOS, power down your PC, and remove your power cable. The debug LEDs are for CPU, DRAM, BOOT, and VGA this is shown in the photo below:īefore we get into troubleshooting, we always recommend a CMOS clear, as this can resolve some POST issues. Please reference the photo below for the location of these debug LEDs and other significant components. POST or the Power On Self Test is how the motherboard checks for hardware faults. The N7 Z490 has Debug LEDs that show what is preventing your PC from passing the POST. If you are encountering a black screen at your PC's startup, this may indicate a hardware fault with either the N7 Z490 or the hardware installed to it. ![]()
