Hey everyone! I'm facing some issues trying to install Windows 11 on my newly built PC. Here's my parts list: I have a Gigabyte B850 Gaming X WiFi 6E motherboard, AMD Ryzen 5 9600x CPU, Cooler Master Hyper 212 Spectrum V3 cooler, 32GB Patriot Viper Venom DDR5 RAM, Samsung 990 EVO Plus 1TB SSD, a PowerColor Reaper Radeon RX 9070 XT GPU, and a MONTECH Century II 850W PSU.
I successfully completed POST, but I encountered an ami screen stating: "New CPU installed, fTPM/PSP NV corrupted..." I chose the option to reset fTPM and made it to the BIOS, where everything looks good: the motherboard, CPU, RAM are all being recognized. However, I can't install Windows 11 using my USB drive.
I've formatted the USB for FAT-32 and used the official Windows 11 media creation tool, but I keep getting errors like "0xc000098" and "0xc0000221." I've tried reseating all cables, the RAM, the GPU, and the SSD, but nothing seems to help.
I'd really appreciate any insight or advice on how to successfully get Windows 11 up and running. Thanks!

Have you tried using a different USB flash drive? Sometimes the media can be the issue. I recommend downloading the Windows 11 ISO and using Rufus to create a new installation media. It tends to be more reliable. Also, double-check your connections; I noticed a couple of small errors in your post about the EATX and PCIe connectors, just a heads-up on that! Let me know if this helps!
You might want to consider turning off secure boot in the BIOS while installing the OS. Some systems have issues with that feature enabled during installations. You can enable it again after you successfully boot into Windows with TPM 2 enabled. Just a thought from my experience!
Thanks for the suggestion, Simagus! I'll try disabling secure boot before the install. Hopefully, that makes a difference!

Thanks for the tips, TechWhiz! I tried a couple of PNY USB drives, but I might check if I have another brand lying around. I'll also dive into Rufus and adjust the settings, especially the GPT vs MBR part, as I got lost there.
