TridentZ neo (2x16gb)
ROG Strix B550 mobo
EVGA 850W Supernova G+

PC won’t boot past mobo splash. Can’t load into bios settings. Led lights on mobo get past DRAM, CPU, VGA, then holds a green light on BOOT.

Have tried removing CMOS battery, reseating RAM, reseating GPU, different RAM slots, removing external devices.

PC was working fine yesterday and wouldn’t boot at all today.

Any suggestions are greatly appreciated. Thank you.
 
Removed the HDD (seagate barracuda) and was able to boot into windows. Maybe the HDD died? Why would this prevent windows from booting if it is not the boot drive?
