I listed the specifications for the MOBO: Asus B85-plus CPU, Intel i7-4790, non-K RAM, 16GB Gskill RAM, GTX 970 GPU, Sandisk Ultra SSD, Strix SSD, Cooler Master V650 PSU, and semi-modular design. My PC has been experiencing problems for about six months, sometimes it works but then fails to boot the next day with a fan noise and relay click. I performed standard checks—inspected all connections, removed RAM, applied new thermal paste, cleared CMOS—but nothing resolved it. The PSU and motherboard components remain plugged in and functional, though the system still doesn’t power on reliably. I’m considering waiting a few days to see if it improves, as it started working today. This suggests the power supply might be the issue, but I’m also open to the possibility of a motherboard fault. I’ve attached a HWmonitor Log file for reference. Let me know if you need further assistance.
I attempted to make the PSU stop restarting but received another issue. The fans are spinning, yet no output appears on the screen. I tested HDMI, DisplayPort, DVI, and VGA connections, none worked. Removed the GPU and connected directly to the motherboard, but it still didn’t work. I also reset the CMOS. Does this suggest a problem with the motherboard now?
You're asking for a clear explanation of what you connected to the board—whether it was the monitor or something else. It seems the issue might actually lie with the board itself rather than the power supply unit. If the board isn't properly grounded, it could affect the PSU's connection to the sensor or green wire, causing it to cut power. Verify that the board is correctly grounded; ensure all mounting points are secure and that the standoffs are present. The PSU relies on the board to manage the grounding of the 24-pin ATX connector, which powers the system. Inspect header pins and related connections to confirm they're intact.
