System failure occurred post-crash preventing data submission.
Hello everyone, I'm dealing with a 3-year-old system running a Threadripper 3960x on a Gigabyte Aorus Master TRX40 motherboard. The setup has worked well until recently when I left it idle on the desktop and returned a few hours later only to find it had shut down. When I tried to boot again, it would power up but freeze at POST error code 9C (debug LEDs are visible). The screen lights up but stays stuck on the motherboard splash, even though it displays prompts like "press del to enter bios." Keyboard input doesn't respond no matter how hard I try. In the manual, this error is labeled "Detect and install all currently connected USB devices." I've tried several fixes: cleared non-essential components from the board, unplugged all peripherals, removed onboard headers, NVMe and SSDs, used a single RAM stick, swapped GPUs, and switched the power supply. Despite these efforts, nothing has resolved the issue. This system is crucial for my work, so I'd rather not replace it. Here are the full specs: CPU – AMD Threadripper 3960x; Motherboard – Gigabyte TRX40 Aorus Master (rev 1.0); RAM – G-Skill F4-3600C16Q-64GTRSC (4 x 16 GB); GPU – Nvidia FE 2080 Super NVME; Storage – WD Black SN850x 2TB M.2 NVMe; PSU – Corsair RM1000. Thanks!
Consider performing a BIOS reset first. If the USB device fails without any connection, it might indicate a faulty controller on the board. Sometimes components fail unexpectedly. The CPU, GPU, and RAM have all passed testing, so they shouldn’t be the problem. You might need to replace the motherboard.
I noted the details you shared earlier. The steps you took include testing a BIOS flashback, sending the motherboard for repair, and attempting booting with your CPU and RAM. I’m still reviewing whether these actions resolved the issue or if something else might be at play.
