I clarify that when you say "will not boot," it means the system fails to power on or initialize properly. Specifically, the hardware or firmware prevents any startup sequence from completing. If XMP is disabled, it likely affects display calibration but won’t stop the boot entirely—just may cause visual issues. Testing with a Linux USB stick can help determine if the issue lies in the OS or the storage device itself.
I meant to say it won’t start into Windows right away after passing the BIOS, but it freezes when it tries to boot. We’ve tested all cores without XMP enabled and it still doesn’t work. Installing from the official Windows USB caused problems—we removed the NVMe drive, formatted it, then installed on another PC. It seems the issue isn’t with the OS version (Windows 11 22h2) we’re using.
Begin with the basics—remove the mainboard GPU, PSU, and cooler. Place the mainboard in the antistatic bag, attach the cooler, and attempt to boot without the GPU inside the case. Why wasn’t it installed directly on the system? Restart the BIOS to factory settings and try booting again. If needed, reinstall the device. Drivers may differ depending on the system; for AMD systems, booting on a new Intel platform can be challenging due to missing AHCI drivers at startup. Since the original system wasn’t specified, it’s based on assumptions.
The responses explain the reason behind the OS installation on a different system. We encountered issues with the Windows USB installation, removed the NVMe drive, formatted it, and then installed Windows on my existing system. My hardware includes a 12900k, 3090 Ti, and a 13900K CPU without built-in graphics. The BIOS was updated, and since I’m using one core, Windows boots successfully only when that core is active. I plan to take the PC to the place where the parts were bought to see if further troubleshooting is possible. I’ve only assembled a few PCs before, but this hasn’t been a problem for me.
