What's the best way to figure out what is keeping my PC from turning on? Ideally I can identify the problem piece and swap it out. I'm strapped for cash right now and would like to avoid building a new PC. Problem description: PC non-responsive to power button on case and power button on motherboard. More background My PC turned itself off while I was writing in google docs and won't turn back on. The led that indicated it was running turned back on like it power cycled, but nothing showed up on my monitors. Tried power-cycling it a few times, and it did power down and back up, but never made it all the way to the windows 10 desktop. Now the power button doesn't seem to do anything at all anymore (there's an LED under it that glows green when the PC is on. LED is staying unlit). There's no led on the PSU, but there's an LED on the motherboard that is green. According to the manual that LED indicates that the board at least is receiving power, so I'm guessing the motherboard is fine. Attempted fixes: verified board is receiving power via power status LED on mother board. I've unplugged and replugged the power cable to the PSU. Pretty sure power from the wall is fine because it uses the same power strip as the monitors and they're getting power. Recent changes: no HW changes in months. I Install new games fairly frequently but that seems unlikely to be related -- Operating system: Windows 10 64-bit System specs: LLSix posted:PCPartPicker part list / Price breakdown by merchant Above is the original parts list when I built it in Aug. 2016. I've added another SSD since than and a wireless networking card. Motherboard manual is https://dlcdnets.asus.com/pub/ASUS/mb/LGA1151/Z170-A/E10611_Z170-A_UM_V2_WEB.pdf Location: USA I have Googled and read the FAQ: Yes

Get another PSU to test with ASAP, sounds like it has fully failed because the LED light on the PSU itself should be green as its a self-test diagnostic indicator light. Chances are it's blown a fuse, transistor/circuit or something else that you wouldn't want to be using anyway even if it did power on the computer. The fact that the mobo LED is on but the PSU LED is not, also indicates that its putting out bad/low voltage and can't run the system's load any longer. TLDR; Get a new power supply More troubleshooting here: https://www.techrepublic.com/article/learn-to-troubleshoot-power-supply-problems/ https://www.pcgamer.com/is-my-computer-power-supply-dead/ Slayerjerman fucked around with this message at 23:20 on Oct 5, 2019 |
