LED stays lit briefly before your PC powers down—what could be causing this?
During startup, your motherboard remains illuminated briefly before the system powers down. It’s unclear if the power supply is faulty or if a cable issue exists. I verified all connections at the outlet and power supply, but the problem persists. Any suggestions for resolving this would be greatly helpful. Additional details: the issue began after moving my speaker, which may have caused a shock that disrupted mouse and keyboard connectivity.
Which motherboard are you using? The green LED typically serves as a debug indicator, but its exact purpose can vary. Please share a picture if you'd like further details.
The mainboard is the "Tuf gaming B550-Plus (Wi-Fi)" and the blue light that flashes before powering down is the "Boot" indicator. You can also remove the protective cover to see it more clearly, which will make the process easier.
I don’t think it’s the RAM issue. I haven’t adjusted anything related to it, and the last steps I took were repositioning my speaker and powering down the machine when I lost access to controls.
Yes, the green LED typically indicates the VGA connection status.
