Hi there, new PC builder. Your setup seems to have a few issues. First, when you power on the monitor, it keeps reporting that the HDMI port signal isn’t found. Second, your motherboard displays a red LED for the CPU and an orange one for the RAM. You’ve already checked the CPU connections—no bent pins, just solid installation. Your memory sticks are in A2 and you’re only using one at a time to test. The CPU fan is spinning, but only the middle fan in the case is active. The GPU is securely placed and has two PCIe 8-pin ports firmly attached. The GPU lights up, yet the fans remain silent. There are two CPU power connectors and all other cables are tight. You’ve tried the CMOS screwdriver test. Here’s what you might want to consider: verify the HDMI cable connection, ensure the monitor is properly seated, confirm the CPU and RAM are correctly installed, check for any loose connections on the motherboard, and make sure the GPU power cables are secure. If problems persist, consider a professional diagnostic.
Hey there! Are you eager for results? Memory training might require 15 minutes or longer. Both devices are connected—are they using a splitter or separate MBOO connections? It could be a DOA board; you might try updating the BIOS via the Flash BIOS button (see page 52, 54 in the PDF).
No progress yet. Attempted BIOS flashback and memory training, but nothing happened. Could it be I'm doing something wrong or the motherboard is faulty? Spoiler: Spoiler: Spoiler: Spoiler: Spoiler. Updated July 17, 2025 by SansVarnic.
