Which component is responsible for preventing the PC from starting?
Hi there. This is my initial attempt at assembling a PC. I've been working on it for weeks, but I'm still facing the same issues. Everything seems assembled correctly and the system powers on normally. Fans are running, the motherboard indicator is on, and no alarm sounds. Connecting an HDMI to DVI port shows no signal. The mouse doesn't light up either. After swapping the motherboard, everything works again without the GPU, but the mouse still won't illuminate. When I turn it back on with the GPU installed, the mouse lights up. After turning it off and installing the GPU, the mouse stops working. The monitor ports also don't respond when the mouse is plugged in. It seems like the GPU might be causing this problem, or possibly the CPU is the culprit. I'm checking the BIOS for a potential fix. Have anyone encountered this issue before? Thanks!

Have you checked if the BIOS was updated? The AM4 boards require the most recent BIOS for the Ryzen 5000 series.
The Ryzen 5600 lacks an integrated graphics card, meaning you must install a dedicated graphics card to meet P.O.S.T. requirements. Without an iGPU, DVI and VGA connections won't function properly. The motherboard should not display any beep codes unless a speaker is connected. Since your motherboard doesn’t have Debug LEDs, you’ll need a separate speaker from the case. Have you considered using an HDMI-to-DVI adapter? It might be defective.
Start by confirming your monitor cable is connected to the motherboard's video port or the GPU's video port. It’s worth noting that without an iGPU (especially non-Ryzen models) the port won’t work, and many people aren’t aware of this distinction. Next, test the cable and monitor with other configurations if you can. Early on, checking if the RAM’s SKU appears on the board’s Qualified Vendor List is crucial—this matters a lot for Ryzens, as they have strict requirements. RAM issues can lead to no video boot or POST failures, making it hard to diagnose the problem. Edited September 20, 2022 by An0maly_76 Updated further
I didn't modify the BIOS. It appears there are several methods available for updating it. Find the best approach without needing a display. Thank you.
It's good to hear you have the right cords—just DVI and VGA. An HDMI-HDMI cable works fine, you can grab it tomorrow. The problem might be solved without a motherboard speaker; if needed, I can test the board. Thanks!
I tested both ports, but nothing worked. Started with the video port first—no signal at all. Motherboard port also didn’t help. When connecting the laptop to a monitor with the same cable, it functioned. Using the exact same cable for the desktop monitor didn’t connect. I know the RAM matches the motherboard specs. Do you have any resource to check if RAM is compatible with your CPU? The AMD site doesn’t show anything there. Thanks!
Most manufacturers list a maximum RAM speed for their chips, but this isn't always a strict limit—some may exceed it slightly. How did you confirm the RAM would work with your system? If it wasn’t listed on the board manufacturer’s Qualified Vendor List, it’s hard to trust. Crucial and Pangoly both confirmed the Ballistix kit I used in three projects worked with each of the three boards, though one caused issues. For the two that needed fixing, swapping the RAM resolved the problems. The third is on leave and not urgent to address right now. Edited September 20, 2022 by An0maly_76 Revised
The documentation doesn't mention RAM details, but many sources suggest a 3200MHz maximum. Those references seem reliable. The manual advises reaching out to the motherboard maker for BIOS updates—perhaps that's the problem. Checking the manufacturer's site confirms Kingston RAM 3200 is listed for this board. You might test swapping it in to see if performance improves.
I doubt the RAM is the main issue here. Before exchanging parts, I’d verify your clock speeds, voltage and frequency are correct. These can also cause problems if misconfigured, and DOCP doesn’t always automatically find the right settings. The RAM specifications you have match the board’s requirements—22-22-22-52 at 1.2V. My unit required 16-18-18-36 at 1.35V, but DOCP wouldn’t recognize it at those values, so I had to adjust them manually. You may want to review the DOCP profile for that configuration.
