I just installed a new build with these details: i5 12600k, b660m mortar, WiFi, DDR4, Corsair verngeance RGB, 3600 RX6900xt, red devil 750W, BIOS version 7D42v1A. I configured the settings carefully—boot options, Fastboot, Secureboot, Trusted Computing, Power Management, USB power, and more. Everything functioned smoothly until I powered off the machine. The next time I tried to turn it on, the RAM and GPU LEDs stayed lit. An error debug LED toggled between RAM and GPU status until it stopped, preventing the PC from booting. Now I’m stuck removing three RAM sticks to fix a BIOS error, then reinserting them and applying XMP settings. It’s quite complicated because I have to reset everything every time I start up. I’m unsure if the issue lies with the RAM XMP profile or if my BIOS was set incorrectly.

I was using the Trident RGB 32GB 2x16 setup two days ago, connected to port A2 B2 with XMP 3600 enabled, but I couldn’t boot. I expected a RAM error message indicating 64 4x16, but it didn’t happen.

Run the RAM at 3200Mhz and see if it resolves the problem.

I'll attempt it again, but I'm still puzzled why turning off the computer for over 10 hours prevents booting, while a shorter shutdown (around 2-3 hours) allows normal startup.

Only memory exercises and similar techniques are performed during a cold boot to boost startup performance, resulting in quicker launches. You might have observed this when your PC takes longer to power up after a period before restarting versus instant-on behavior right after shutting it down.
