I used to have 2x16 GB Corsair Vengeance RAM. I needed an upgrade, so I switched to the Corsair Vengeance 64 GB (2 x 32 GB) DDR5-5600 CL40 memory, but with the new sticks PC wasnt loading and had red error lights on Ram and yellow on CPU. I switched back to the 2x16 GB sticks, and it worked just fine. After updating my BIOS (which I had never done since building the PC), the system started working with the 2x32 GB sticks. However, after the BIOS screen, I get a black screen and nothing happens, with no error codes. After a few attempts to turn the PC off and on again, I occasionally get a "Windows failed to load" error, or it will boot into Windows without issue. What I dont understand is why does it work "sometimes" and load correctly?

Here are the fixes I have tried:
CMOS reset
BIOS default settings
moved to the newest BIOS version E7D75AMS.1m1
and a ton of videos having me trying to repair via the troubleshoot windows after I get a blue screen.
bought 4x16 corsair vengeance and still same issue with black screen (so I made sure it wasnt a ram issue with the 2x32
Full system reset with no saved history

I just created a ticket because I have the exact same problem: error message, then magically fixed, I wanted to update the bios and after restarting: the PC turns on, the screen too, but black screen, no connection between the two. What's going on?? Maybe a bug in the latest update... I don't know anything about it, I hope someone can enlighten us!
