Details: MB AsRock Taichi x670e BIOS v2.02 (as received) CPU AMD Ryzen 7 7800X3D GPU Nvidia 3060ti FE RAM G.Skill Trident Z 5 Neo DDR5-6000 2x 16GB PSU BeQuiet Dark Power 13 1000W Cooler Noctua NHD15 Storage M.2 Samsung 980Pro 1TB, 2x 870Evo 250gb, 1TB HDD 5x Case Fans All parts arrived new except GPU and older SSDs/HDD. I ran my first test after installing the motherboard with CPU, RAM, and GPU in my case. Everything functioned properly; components appeared in BIOS and CPU temperatures were normal. I restarted and kept building. Project completed, reinstalled everything and plugged back in. Only the MB RGB lights stayed on—RAM RGB didn’t activate. I've tried standard troubleshooting: changed outlet, switched PSU to known good one, unplugged all except CPU and MB, re-seated RAM. I haven't re-seated CPU yet. Would this help? Should I consider a BIOS update or return the board? Could it be an overcurrent issue from using all slots? The case included a 5-slot fan hub with one header; I used all five slots. Was that enough to damage the board?
Did you attempt to restart the computer by pressing the power button switches on the motherboard? Verified that all connections on both sides of the power supply unit are secure.
Connected the two SSDs and one HDD using SATA, installed the power supply inside the case (previously outside for testing), handled all cable connections, and connected the front I/O. Added HD audio, power button, LEDs, USB for front I/O, and USB-C for front I/O. Also connected a USB with Windows ISO for setup on the front I/O ports.
Before touching anything, I suggest rebuilding it from the ground up. As mentioned, the components seem functional, but the main concern is the fan hub. Consider starting with a basic setup using just the motherboard fan headers.
I made several changes to the process. First, I flashed a new BIOS version over AsRock Flashback. Then I re-seated the RAM and tightened the CPU cooler more firmly. I also reconnected all power cables and tried booting with just the CPU, M.2 drive, both RAM modules, and the cooler. It worked, and I got into BIOS via video output through the onboard graphics. After that, I installed the remaining fans, including the fan-hub setup with three fans and two more separately, along with the GPU. The system booted again (video output over GPU). I connected all drives, managed cables, and set up front I/O, audio, and USB ports. Booted into Windows from one of the SSDs. From then on, everything ran smoothly. I finished the build by managing cables and installing the PSU in the case. During the Windows installation, I faced some driver problems, so I used a workaround by installing via WIN 10 USB and upgraded to WIN 11 for a clean setup. The following two weeks went without major issues. However, today I ran into the same issue again—my system’s memory was completely unresponsive. This time I tried unplugging all USB and display cables, but that didn’t help. I tightened the CPU cooler again (it was already snug), but it didn’t resolve anything. I cleared the CMOS and unplugged my old HDD, which had been acting strange recently. I re-seated the CPU 8-PINs (one of them worked). Booted into code 15 for memory training because the CMOS was cleared, then switched straight to Windows. I’m puzzled by this recurring problem and it’s really frustrating. If you have any suggestions or tips, I’d appreciate hearing them.
