The motherboard emits a beep suggesting an issue with the graphics card.
I assembled the system using both modern and older components. When powering it on, I heard one long beep followed by two short beeps. This pattern appears to point toward a video card issue. Could someone with similar experience explain possible reasons?
One possibility is an incompatibility between the card and the PCI slot—perhaps the card needs PCIe 4 while the slot only supports PCIe 3. The buyer’s notes suggest it might be PCIe 4, but some chipset details indicate PCIe 3 support in certain configurations.
Another thought is insufficient power delivery from the supply unit. The system uses an 850W PSU, which should meet the minimum 310W requirement for this build. This could signal a failing or outdated power source, especially if it’s been in use for some time.
The ASUS PRIME A520M-A II features only a PCIe Gen 3 port, which shouldn’t cause problems since the GPU should function on PCIe Gen 3. Assuming the power supply is adequate, an 850W unit should suffice. These sounds indicate a memory-related fault. Re-seat the RAM modules first. If that fails, test with a single stick in one slot. If unsuccessful, swap to another stick in a different channel.
I discovered references suggesting a single long beep plus two short beeps points to a video card issue. I've also tested various memory setups—using one, two, or four slots—and haven't resolved the problem.
According to Asus's official troubleshooting instructions, a single long beep followed by two short beeps usually indicates a RAM problem. Here’s the relevant link. Below is the suggested path. You mentioned you’ve already tried fitting RAM in different slots and removing the CMOS battery each time—have you also tried unplugging the PSU and turning it off, holding the power button for a moment? This helps drain power while the CMOS battery is absent, allowing BIOS settings to reset and the RAM to attempt detection. If this doesn’t resolve the issue, proceed by checking and reinserting the CPU. Why? Because if the RAM pins on the CPU are bent, the system can’t recognize it, triggering a code error. This might happen if they were bent during reinsertion or if screws were over-tightened. It isn’t a CPU-specific fault since all other connections appear normal. If the pins look straight, the problem could stem from an overly tight cooler or heatsink. To test, simply reinsert the CPU without tightening anything first. Place the cooler, heatsink, or block on top of the CPU and power on without connecting the fan. Lightly touch the heatsink with your hand—if it boots, gently tighten the screws by hand only. If it still doesn’t start, disassemble the PC and remove it from its case. Rebuild it on a non-conductive surface, starting with the CPU, motherboard, RAM (reinserting each slot), GPU, and PSU. Avoid putting anything in USB ports or SSDs/HDDs yet—just focus on basic components. The aim is to see if it boots into BIOS or shows no storage/OS errors. If successful, install RAM one by one, beginning with two, then the OS drive, followed by keyboard and mouse. If this fails, you may need professional help. In my region, some repair shops offer free diagnostics—just let them know what you’ve tried beforehand.
