The PC build stopped working suddenly, even after the fans started for just a second.
Hi, after roughly one year of use my PC build isn't starting up anymore. Signs include: - The system suddenly stopped working. - When trying to restart, fans and CPU fans briefly activate before the PC shuts down. - If I power off the PSU for a few minutes it restarts into BIOS. In BIOS I noticed the 12V rail dropping to 10-9V (red marked), sometimes returning to 11-12V. - After exiting BIOS, the PC stopped again. - Now the PC only starts with the initial fans and CPU fans turning on. This seems more like a PSU issue rather than problems with the motherboard or other parts.
The voltage drop suggests a power supply problem. If you have another PSU available, test it to see if it starts up. No complicated steps required.
