I've been struggling to get Windows 10 installed on my new PC for an entire day now, and it's really stressing me out. When I first tested the components outside of the case, everything was perfect, and I managed to install Windows 10 without issues. However, after putting everything into the case, I'm hitting all sorts of errors. I checked all the cables and reseeded the nvme drives, but now the PC just boots into the BIOS. I attempted a fresh install of Windows 10, but it failed. I even tried installing Windows 11, but that sent me into an endless reboot loop. Each installation attempt results in various BSOD errors like 0xc0000005, cache manager, critical process died, and now I'm seeing 0x8007025 and 0xc00021 after removing a RAM stick. Sometimes it even gets stuck on the Asus logo. I have no idea what to do and I'm worried that something might be broken. Any advice would be greatly appreciated!

It sounds like a case-related issue. Since everything worked fine outside the case, check if you used standoffs correctly. Make sure you're only using standoffs in the holes of the motherboard designed for them. Also, confirm that nothing from the I/O shield is touching the motherboard or ports. If you've changed configurations, make sure your RAM is properly seated before securing the motherboard in the case. When reinstalling Windows, it’s best to have only the target drive connected and to secure erase the SSD first.
If your PC is booting fine outside the case, it might be a short circuit or grounding issue due to a misplaced screw or a problem with the case buttons. I've had cases where the reset button was faulty, causing all sorts of strange behaviors. If the reset button isn't working, it could very well be affecting things. Make sure everything is properly seated and that there's nothing metallic touching your motherboard.
Another thing to check is your USB drive used for installation. Recreate it using a reliable tool. Also, sometimes installing Windows 11 can lead to instability, so sticking with Windows 10—even if it’s been tricky—is a good approach for now. If you haven't done it already, try using a different USB port or even a different USB drive.
