I mistakenly pressed the reset button on the PC case, causing your computer to fail to power on.
Turned on my PC by mistake and accidentally pressed the reset button. It doesn’t power up at all—no response from the screen or mouse. The motherboard’s RGB light is lit, but nothing else functions. I’m unsure if the motherboard or power supply unit is faulty. Any advice would be greatly appreciated.
Turn the power button on the PSU, wait a few seconds, then attempt to restart it. If unsuccessful, repeat the process and reset the CMOS by removing the side panel and holding the bottom edge button for ten seconds.
The button may be jammed. It's possible to take it off the front panel connections if necessary.
I just tested it but no power came through. It looks like both the reset and power buttons are on a single 9-pin connector, so I tried using the power button on the motherboard and still got nothing.
Have you experienced any issues with the computer before? I initially assumed this was unrelated to your reset attempt, but it happened simultaneously. If it isn’t there, a potential cause could be the reset button pin being improperly seated, which might damage the motherboard. This idea came to mind while writing this message. Would you receive a response from the motherboard? Here are my suggested steps:
External checks:
1. Firmly press the reset button a few times, ensuring it moves correctly.
2. Disconnect all connected devices, keeping power and monitor on, then attempt to boot.
3. Turn off the power supply, unplug the machine, and leave it unplugged for at least five minutes before trying again.
Internal checks:
4. Remove the power and reset buttons from the motherboard and power on the computer through the board.
5. Disconnect the GPU and try booting afterward.
6. Check if you have sufficient RAM; remove any RAM sticks to test.
7. ...Cry? WTF? After these steps, it’s hard to figure out what to do next. You might consider trying other components like SSDs, but I doubt they’d stop a boot even if faulty. Maybe verify the power supply is delivering adequate voltage?
I understand this can be frustrating—just having problems without understanding the cause is exhausting.
It was the final attempt! Initially I used just the button on the MB, but it failed. Then I removed the entire CMOS battery, reinserted it after a short wait, and the system started working perfectly without any problems. Thanks again for your help!
