Mainboard possibly damaged after Ryzen 5000 installation
Mainboard possibly damaged after Ryzen 5000 installation
Hey there, I recently used my PC just fine one evening (without heavy use) and the next morning it wouldn’t turn on. I’m running out of ideas but thought I could post here for suggestions before replacing anything. Nothing happens when I press the power button or short the board pins—no lights, no fans, not even the PSU fan. I turned on startup after power restore, but that also failed. I don’t remember if the system was in sleep or shutdown mode that evening. I unplugged all cables from the mainboard and tried powering the PSU through the ATX pin, which caused a spinning PSU fan and fan lights powered directly from the PSU. The CMOS battery shows normal voltage, and the board reset didn’t fix anything. Whether I have the GPU in or not doesn’t change the issue, but since no error lights appear on the mainboard, I don’t think any other component is faulty. All components look fine. My setup is a Ryzen 5 5600X (aircooled), MSI X370 gaming pro carbon (first-gen Ryzen), Zotac RTX2070 Super Mini, Corsair Rm750x PSU, two PCIe3 SSDs from Lexar, and two WD HDDs, running Windows 11 Pro. I’m hoping someone can help, as the next step might be swapping out the board.
You noted the absence of error indicators or POST codes on the motherboard, which could point to an issue with the standby power circuit—responsible for keeping the board active when it’s off. If this component isn’t functioning, the motherboard may not receive the correct signal to power up. Replacing the motherboard and rebuilding it might be the simplest solution. You’re on the correct path, having already tried everything I’d suggested.
