No, your motherboard isn’t toast—it’s just a piece of hardware!
Hi everyone, I completed the assembly on the PC and powered it up for the first time. The fans were running and the green LED lit up on the motherboard. No output appeared on the screen, so I verified the HDMI and keyboard USB connections (pushing them in more) before the machine shut down. Now it won’t turn back on. I ran a paperclip test on the PSU and it functions properly. I removed the motherboard from the case, leaving only the CPU and cooler inside, and attempted jump-starting with a screwdriver, but it still doesn’t power up. I inspected the CPU for bent pins and re-seated it as well. I’m concerned there might be a short or damaged board. Any additional steps you recommend?

You're asking about what "it won't turn back on" refers to. It could mean the fans won't spin, or the LEDs won't activate. Let me know if you'd like clarification!
Your system started up but then cut out and won’t restart. This could mean a wiring fault or a faulty part. Verify the 24-pin ATX and 8-pin CPU connectors are securely attached. If using a modular power supply, confirm cables are correctly plugged in on both sides. Switch to another power outlet or PSU cable to rule out delivery problems. Clear CMOS by removing the battery, unplugging the PSU, holding the power button for 30 seconds to release leftover charge, then wait a few minutes before reinserting the battery and restarting. Try booting without RAM installed—if the board responds with a beep or error codes, it may still have issues under stress. Look for short circuits on the motherboard by checking standoffs, loose screws, and signs of burn marks or damaged parts. If debug LEDs or a speaker emit beeps, they indicate problems. If these steps don’t resolve it, the board is likely dead; a CPU failure is also possible. Testing with another board or CPU can confirm the source, but if unavailable, consider returning the motherboard for warranty support.
I purchased a PSU tester which verified the power supply works. It seems it’s best to abandon the motherboard now. I hope I can understand why it failed at first!
