Device fails to power up due to technical issues.
Case: Argus E1 Motherboard – Gigabyte Z690 Gaming X Cooling, Cooler Master ML240L V2 PSU, Gigabyte 750W 80+ Gold, GPU Gigabyte RTX 3060ti Gaming OC, RAM G.Skill Ripjaw 2x16GB, CPU i5 12400f
When I first assembled this system, I attempted to power it on. It illuminated briefly before powering down. Later, I discovered a solution by connecting the correct pins to discharge the CMOS. After that, the machine functioned normally for nearly a year. About two months ago, when I tried to turn it on, the case’s power switch failed completely—pressing it yielded no response. I learned to boot from the Q-flash button. For most of the past month, I kept the PC running only to update Windows. After completion, the cooling LEDs remained lit. I pressed the case power button and it finally started. It worked for weeks before stalling again.
Yesterday, post-Windows update, the cooling system still displayed lights. I forced the power switch on the PSU and it rebooted successfully. That was a hopeful moment. I decided to leave the machine off overnight. After shutdown, the cooling LEDs stayed on, so I flipped the main power off. The next morning I reactivated the PSU and pressed the power button—still no response.
I disassembled the case and tried the Q-flash button. The PC booted up and shut down once more. Now it wouldn’t turn on at all. Even when I connected the power cord normally, the LEDs stayed illuminated. My Blue Yeti microphone’s red light continued to flash while plugged in, but after this incident, the blinking slowed considerably—pressing mute didn’t alter its state.
I’ve been experimenting and researching. It seems the PSU, GPU, and RAM aren’t the root cause. The closest fix I achieved was removing the lithium battery from the motherboard, holding the reset switch for 10 seconds, then reinserting the battery. The power supply lit up a rainbow, and the fans began cycling green—a sign of recovery. However, the system still wouldn’t boot. After disconnecting power and reconnecting the lights, it remained unresponsive.
From what I’ve gathered, this appears to be a recurring issue with certain Gigabyte boards, possibly linked to CPU compatibility. I suspect a mismatch between the CPU and board might be involved. While I’m not an expert, I’m open to advice. My confidence is wavering; any guidance would be invaluable.
Consider removing the CMOS battery, disconnecting the PSU, and pressing the power button for over 30 seconds. You’ve likely tried this before, but extending the hold to more than 10 seconds may reset the BIOS. Alternatively, use the Q-Flash button to update the BIOS if needed.
The GM explained the situation. I didn’t realize this happened. During a power outage in my neighborhood, I was in the middle of a game when it occurred. I thought the outage might have damaged the PSU, but after replacing it with a Corsair 750W unit (the exact model I’m not sure about), the problem persisted. I assumed there was another issue elsewhere.
I’ve just tested it again and still nothing. I reassembled my PC and put it back in place temporarily. I also observed a faint high-pitched ticking noise when the PC powers on. Another detail I missed earlier was that during this morning’s issue, my microphone mute button blinked rapidly—about 2-3 times per second when muted—but now it’s blinking slowly, roughly once per second. That rhythm matches the ticking sound I’m hearing. I’m not sure if this is important, but it suggests the problem could be on the motherboard, since that’s where the microphone connects and the cooling LEDs are also linked to it.
