![]() How to Troubleshoot Red Light Errors on a Motherboard?.How Can You Tell If Your Motherboard is Dying?.What Does the Red CPU Light on a Motherboard Mean?.How to Read a Red Light on a Motherboard?.If using a PCIe riser cable, try testing the GPU directly connected to the motherboard to rule out the riser being defective.Try a different GPU, if you get POST on a different card, then the GPU you were using may have a defect in it.If you pass the POST on the other slot, please let our Customer Service Team know, this indicates a defect in the motherboard. Please try switching the GPU to the other open PCIe slots on the motherboard.Then verify that the motherboard’s PCIe slot is un-damaged. 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 B550. Verify that the SSD being used is an M.2 NVMe SSD (M-Key).If a particular 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. If a particular DRAM slot is not working properly, please contact our Customer Service Team for assistance. 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 RAMs 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. Make sure 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 B550 (AMD Gen 2-3).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: Remove your CPU to verify that the CPU 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 that is lit up on your motherboard Wait 30 seconds to ensure there is no residual power in the PC then press and hold the Clear CMOS button for 3 seconds. To clear CMOS, power down your PC, and remove your power cable. The Clear CMOS button is located on the rear I/O and can be used to revert BIOS settings to default. 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 major components. POST or the Power On Self Test is how the motherboard checks for any hardware faults. The N7 B550 has Debug LEDs that indicate what is preventing your PC from passing the POST. If you are encountering a black screen at the startup of your PC, this may indicate a hardware fault with either the N7 B550 or the hardware installed to it.
