5yr old build, won't post
Thanks for your update. The build was previously stable, but now it won't power on after returning from work. I still have power to the USB ports. I've tried several fixes: swapping the PSU, changing the MB power switch, removing components except the CPU, and clearing CMOS. The system is still silent on the MB. The motherboard appears to be functioning, so it's likely the memory module is dead.
Welcome to the forums! There should be some way that it communicates POST codes. Either LEDs or beeps (you might need to install the speaker) to let you know what it's hanging on. Do fans spin? Regardless, my guess is dead mobo. You're on the upswing of the bathtub failure curve
Thanks for the update. No LEDs on the MB, testing with and without speakers didn’t show any activity—no sounds, no lights, no fans. I only notice power coming through the back I/O and USB ports. My Ethernet stays on when plugged in, and USB devices get power. This suggests the issue might not be a dead MB, but rather something affecting the CPU or its power delivery.
