No POST signal and strange debug lights
No POST signal and strange debug lights
Standard situation I followed all the steps in the MG2R-Guide except 8,17,18 since I lack a VGA/second PC. No changes occurred on the setup. Strange things: - Each time I power on the PC (using my screwdriver), the CPU and DRAM LEDs flash for about 10 seconds, then the CPU LED turns off and the DRAM also stops after roughly 2 seconds. - When I turn off the PC (with the screwdriver), the DRAM light comes back on until the system shuts down. Specs: CPU - AMD Ryzen 7 7700X 4.5 GHz 8-Core Processor Cooler - ARCTIC Freezer 36 MB - MSI PRO B650-S WIFI ATX AM5 Memory - G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL36 Storage - Kingston NV3 1 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive GPU - Gigabyte GAMING OC Radeon RX 7600 XT 16 GB BIOS : AMI BIOS Version 7E26v1L Other (important) stuff: - Motherboard was missing M.2 clips for my SSD, so I improvised with a regular screw and nut (refer to photo) - I'm new to assembling PCs (this is my first build), so I might misinterpret things and make some errors. Please be understanding and patient.
These results aren't very informative. I have another motherboard, and mine handles the CPU, DRAM, VGA and boot process every time it restarts. When powering off, they briefly flash a few times until the battery dies. The debug indicators only make sense if they remain active. As long as the screw doesn’t touch more conductive surfaces than a standard screw, it’s fine. You can even experiment with fishing line or duct tape for a DIY fix. Have you tried booting your computer without the GPU? Your CPU has an integrated graphics unit, so you could connect your monitor to the motherboard slots. This helps eliminate whether the GPU is broken or functioning properly. If nothing works, try booting with just the essentials—motherboard, CPU, RAM and power supply. Remove everything else (including the SSD). This should let you access the BIOS screen. Then shut down, add one component at a time, and restart until you identify the faulty part. Good luck!
It's a chance scenario. Have you verified if the BIOS on the motherboard matches your CPU? It seems unlikely, but it's worth confirming. Did you attempt to reset the CMOS memory? The following action involves testing each part individually on another machine.
The BIOS is the latest complete update for the motherboard. Although I understand the Ryzen 7 7000 series should still be supported, I've already attempted to reset the CMOS and swapped out the CMOS battery with a fresh one. Unfortunately, I don’t have another PC to test these components, so if it doesn’t work, I might need assistance from a tech store.
Recent boards maintain support for older chips during upgrades. They have sufficient memory to hold data for all compatible CPUs. Another user noted that starting up might interrupt Memory training. The boot time can vary, sometimes taking a few minutes for newer motherboards. This process helps verify your components. Requesting a quote is advisable—it shouldn’t be overly costly for a repair shop. If you return the board and/or CPU, I’d evaluate the best timeline for repairs if issues arise.
Also a possibility. I think the OP didn't mention how long he waited before declaring the POST was unsuccessful. Since he is new to computer assembling, this is certainly worth asking.
