System struggles to load, only black screen appears. Monitor lights seem active but display remains absent. No boot devices detected; BIOS access blocked when SSD is unplugged. Occasionally no error messages appear, just a "no display" notice. Dr. Debug codes show A8 for CPU/RAM/GPU and 99 for boot issues. Attempts to remove or change components didn’t resolve the problem. The A8 presence suggests CPU problems, but the lack of boot support raises concerns about motherboard health.

A8 will connect to RAM. Do you happen to be using Corsair Vengeance LPX RAM?

I don't understand, the original RAM is a Geil Super Lute RGB model (I haven't heard of the brand before). My test RAM is G.skill Trident Z, but it doesn't show any error messages and also doesn't display anything.

I'll look into this. From what I understand, the customer hasn't updated the BIOS yet, and there was a sudden refusal to post a display one night when powering up the system. Before that, there were occasional random restarts or shutdowns. Initially, I considered a PSU problem, but testing with another PSU gave the same result—no display issues. Further research into the display ID problem suggests it might be specific to 30-series cards and only affects HDMI, DisplayPort, and a 20-series card.

Based on my observations, the Zen+ mem controllers tend to be quite particular about RAM settings. On my 2600X, adjusting the VRAM to 2133 usually worked fine, but sometimes it would cause no display or intermittent issues. Exceeding 2866 often led to corruption and boot loops.

I placed an order for a new motherboard for my PC. I’ll check its performance next week and keep you posted if it fixes the problem or if I discover something better.

Still no success with the new motherboard, but maybe I messed up by using an incompatible M.2 slot for the CPU. So far, only a post confirms it recognizes CPU, RAM, and SATA devices. The EZ debug panel freezes on VGA, so I’ll have to wait until tomorrow to test another GPU. Quite odd problem.

The issue has been fixed with a new BIOS update. Initially, the BIOS came out of the box incompatible with certain hardware. After updating to the Windows 11 support version, it worked properly. The 5000 series CPU still needed a separate fix.
