Random shutdowns on the new A520 model
Hello, a friend of yours recently installed an AMD Ryzen 5500 system and is facing booting issues. It powers on without showing anything or with fan noise and shuts down abruptly—often within seconds. The machine functioned perfectly for about five days before suddenly failing to start. After updating drivers and the BIOS, it worked once again but then would power off immediately after downloading CPU Z. Since then, it’s only bootable twice. Recent attempts involved updating all drivers, using XMP-enabled RAM, and testing different GPUs (RTX 3070, 1070). The case and storage components are new except the graphics card. You’re hoping for PSU troubleshooting ideas; consider testing with another PSU tomorrow when you can acquire one from your existing stock.
Hi. If CMOS clearing doesn't resolve the issue, it's likely time to power off the PC and inspect it carefully. Look for any visible problems, then proceed by repositioning the RAM, followed by the GPU, and finally disassembling components for a fresh build (testing each step). Replacing the power supply is a reasonable approach, though it may require more effort—starting with simpler fixes would be wiser. Based on the heat generated during testing, I suspect some flexing or a loose contact might be causing the problem, and a bit of warmth could either help or worsen the situation (which explains the occasional boot issues).
Thanks for the advice. I've changed to a different setup—1 stick, 2 sticks, slot A, slot B. The hole is now very deep, so I'm testing it on a box outside the case. It's plugged in, not yet connected. I pulled the CMOS battery and adjusted the reset pins. I moved the CPU to confirm the cooler was touching properly. No bent pins detected, should mention that.
It seems PSU is probably the cause. Could you try connecting a speaker near the speaker pins next to the front panel connectors (like power button and LED)? This might trigger bios error codes.
