I recently assembled a brand new computer using completely unused parts. After roughly ten minutes of operation in the operating system, the USB headers on the board and I/O stopped functioning (meaning some fans linked to the motherboard headers, keyboard, and mouse won’t reconnect) and the graphics card isn’t sending any signal to the monitor. No blue screen appears. Still, the CPU fan and all RGB indicators stay active. The LAN port lights also work fine. All other parts connected directly to the power supply remain powered. Resetting the case or motherboard switches won’t resolve the problem. The only solution is flipping the PSU switch.

My system specs: CPU – AMD Ryzen 5 7600X, Motherboard – Gigabyte B650M DS3H AM5 1.0 (BIOS v2), RAM – 2x16GB 5200MHz T-Force Vulcan DDR5 (base ~4800MHz), Case – Phanteks Eclipse G360A, Storage – 1TB Seagate BarraCuda Q5 SSD NVMe PCIe Gen3x4, NVMe M.2 2280 SSD, Power Supply – Thermaltake 80 PLUS Smart 700W, OS – Windows 10 Home. All components are running at their default speeds.

The interval between OS startup and the problem onset varies unpredictably, spanning from three minutes up to several hours.

Check if your system is actively running by looking at the RGB and LAN indicators. Even if the issue seems resolved, it might not be. Also, review the Windows Event Viewer logs for any relevant entries during the affected periods.

Key concern, as this Thermaltake power supply isn't suitable for high-performance gaming graphics cards.

I'm using a dedicated graphics card. I'll check if removing the GPU helps isolate the issue. The GPU and PSU were in an old build before, but it worked fine then. It might be the new parts drawing too much power at once. I haven't done any heavy power use like gaming yet. I'm still puzzled about why the USB headers disconnect too. I plan to disconnect everything except the motherboard to see if the problem persists on the BIOS screen as well. A driver update seems likely, but the fear of something happening during a flash is really unsettling.

Did you mention your GPU, or are you unsure of its model? The issue described was about a random shutdown, but I didn’t receive any information regarding the system’s specifications beyond that.

Oops! I missed the GPU details. It’s a GIGABYTE GeForce RTX 3060 Gaming OC 12G.

You definitely require a distinct power source no matter what the problem is, though it might be true. Curious about how the built-in graphics perform. If it functions, I’d consider testing the graphics card on another machine.

After taking out the GPU and relying on the built-in graphics, the same problem persists. The Event Viewer shows no unusual activity, suggesting a possible motherboard concern.

Your friend's setup with the ASRock B650M Riptide and Ryzen 7700 ran into issues again, even after swapping components. It seems the problem might be linked to the motherboard itself. Investigating what could have gone wrong during assembly or initial configuration is a good next step.
