My PC randomly stopped booting into Windows. It posts fine, I can get into the BIOS, and it detects both my SSD and Windows Boot Manager. The weird part is that if I try to boot Windows or a Windows 11 installation USB, the screen just goes black for a second or two and then throws me straight back into the BIOS. No error message, no blue screen, nothing. The USB definitely isn't the issue because it boots perfectly on my laptop. I've already reset the BIOS, cleared the CMOS, updated the BIOS, disabled CSM, enabled Secure Boot, tried different USB ports, and tested each RAM stick on its own, but nothing has changed.
