PC activates only after pressure is applied to the 24-pin connector.
Hi, one day it shut down like electricity went off, I opened the case and I was thinking loose cables are causing this so accidently discovered pushing 24 pin turns pc on without any power button. after that I thought maybe psu causing the issue and I plugged it on a different computer, it was working perfectly. now I am confused and have 0 opinion what can cause this problem. I need help. PSU: XCP-A600 Processor:Amd FX-6300 RAM: Kingston 4x2 GB 600mhz DDR3 GPU: Amd Radeon HD 6570 Motherboard: GA-970A-DS3P Gigabyte Case : old CoolerMaster case. (I couldn't find the name)
One of two possibilities exists. A crack in the board near the ATX socket, a bent or misaligned pin, or a loose/bent pin in the PSU connector needing some lateral movement to keep contact. This might occur at the ATX port or where the harness connects to the PSU, since some setups create more tension in certain areas.
Shorting 5V to ground activates the system. It seems the motherboard is not working properly.
It's not only about PS_ON to GND being shorted that causes a board to activate. That helps explain the EP45 issue I encountered after briefly powering up the PSU, but I’m curious why it just restarts and then turns off without responding to the power button. It seems to behave normally otherwise—like it would if forced to jump PS_ON to GND—but doesn’t actually post. This suggests a possible CMOS or power button fault, possibly needing a jumper. It might also be a shorted power button or a faulty board, as some units require manual activation before showing the splash screen. Check if the same behavior occurs when removing the power button connector; if not, it could be stuck on 00.
