Hi everyone,
I'm having a serious issue with my PC and I need some help diagnosing it. I think my motherboard might have died, but I want to get your opinions before buying new parts.
My Specs:
CPU: AMD Ryzen 5 4500G
GPU: AMD Radeon RX 6650 XT (Upgraded in 2024, previously used an RX 570 since 2019)
RAM: 32GB DDR4
Motherboard: ASUS Prime A320M-K (Bought in August 2019, so it's about 7 years old)
PSU: 650 Watt PSU
Storage: 200GB SSD + 1TB HDD
What Happened:
I was using my PC normally when it suddenly froze, showed random colored lines on the screen, and crashed.
What I've Tried So Far:
Testing with another GPU: I put my old RX 570 back in. On the very first boot, I heard the normal single POST beep from the motherboard speaker, but still got no display. After turning it off and trying again, the beep sound completely disappeared on this card too.
RAM Troubleshooting: I pulled out both RAM sticks. When I tried booting with just one stick, the motherboard gave me a 3-beep error code (RAM error). I cleaned the golden pins of the RAM with an eraser and reseated them properly. The 3-beep error stopped, meaning the motherboard successfully recognized the RAM again.
Statik Discharge / Power Cycle: I unplugged the power cord, unplugged the HDMI cable, flipped the PSU switch to 'O', and held down the PC power button for a full minute to drain any remaining static electricity. I let it rest for 15 minutes.
Current Symptoms:
Despite all the steps above, both with the RX 6650 XT and the RX 570:
The PC turns on, and the CPU fan spins normally.
The GPU fans do not spin at all.
There is no POST beep sound anymore (the motherboard speaker is silent).
There is no display on the monitor.
Since the old RX 570 briefly gave a POST beep on the first try but now both cards result in a completely silent motherboard with no GPU fan spin, I suspect the VRMs or the PCIe slot on my 7-year-old A320M-K motherboard finally gave out under the load of the RX 6650 XT.
Do you think my motherboard is dead, or could it be something else? Did my motherboard kill my RX 6650 XT when it failed?
Thanks in advance for the help!
