New setup featuring Asus X870-P Wi-Fi, 9800X3D, and Asus TUF Gaming 5090 ceased updates.
At the end of June I upgraded my whole system after purchasing the 5090. Since then, I've faced ongoing issues with the hardware. At first, the screen would flicker every few minutes. Later, I experienced blue screens in Windows 11, possibly due to "critical system process failed." There were no system logs or diagnostic files from these events. Initially, they occurred randomly, and the machine remained functional. Then they began shortly after logging in, each time I restarted. I replaced the power supply with the one listed below, thinking my old 850W PSU might be insufficient. The persistent blue screens likely damaged my LG OLED monitor, even after the PSU change; once a blue screen happened, the speakers would buzz and pop. After one such incident, the monitor began emitting burning odors. I discontinued its use and purchased a replacement. The original monitor is now being repaired by Samsung. From research, the first two issues appeared to be: 1) The Western Digital SSD used as a boot drive wasn't fully reliable on Windows after a recent update. This was a different drive from my previous setup—it was merely a data drive. 2) The flickering problems were a known flaw with the 5090, which disappeared after updating to a Nvidia driver and switching to HDMI instead of DisplayPort. Throughout this ordeal, diagnosing was extremely difficult, especially with Bitlocker and Windows PIN login; entering Safe Mode was nearly impossible. After installing a new boot drive, updating the Nvidia driver, and using HDMI, everything functioned well for about two weeks until recently. Yesterday, the computer failed to power on. It would turn on briefly, but the GPU light appeared and fans started up. The CPU cooler reached 100% as usual, yet it wouldn't stop. No power was sent to peripherals, and no video signal was transmitted. I've tried: deleting the boot drive entirely, re-seating the CPU, reseating RAM, using one RAM stick in all slots, another in all slots, removing the 5090 entirely with only the built-in HDMI, ensuring all cables were secure, removing the CMOS battery while power off, and then putting it back—uncertain next steps. Eventually, I felt discouraged because I was disappointed with this new build, but couldn't enjoy it. BIOS Version: 1066 – This is the latest BIOS version I installed, released in June. Components: AMD Ryzen 7 9800X3D, ASUS PRIME X870-P, WIFI CORSAIR Vengeance, 64GB DDR5 6000MHz CL40 UDIMM, Asus Tuf Gaming 5090, Corsair Nautilus 360 RS Liquid CPU Cooler, Corsair RM1200x PSU, Samsung 980 1TB NVMe, Samsung G8 32" OLED.
Following a CMOS reset initiates memory training, which may require some time. If you encounter a black screen after powering up, allow it to run for up to 10 minutes before turning it off and then back on. The initial boot might feel slower, which is typical. Once confirmed, proceed with the following steps: flash BIOS (USB max 32GB? verify manual, USB version possibly 2.0, unknown, check manual), ensure FAT32 format, update the BIOS file name correctly, confirm GPU OUT, SSD OUT, iGPU IN, and place a RAM module in slot A2 for memory training. After completing these, let the system run for up to 10 minutes before powering it off again. Let me know once you're ready.
I located a vintage flash drive and wiped it using FAT32 formatting. Followed the instructions in the manual—successfully, with the BIOS updated just three days prior. The GPU is active, SSD is accessible, one RAM stick is installed in slot A2. Despite these changes, the issues persist: no video output, CPU fan running at full speed, and still no display functionality, even after ten minutes.
After a fresh BIOS flash and basic configuration (just 1 RAM, no GPU/SSD), with the CPU fan at full speed and no debug lights visible, the issue likely lies with the motherboard or CPU itself. Consider testing the CPU on another board or swapping it with another CPU from your motherboard. If you can't proceed, initiate a return via RMA—this usually indicates a hardware problem. You might ask a friend for help or check retailers that offer returns within a specific timeframe to avoid financial loss.
Thank you for your assistance! I brought the CPU to the store where I purchased it, and they tested it on their bench—it still had the issue. They replaced it with a new one, and they’ll return the old unit to AMD. Everything is now functioning properly.
