[SOLVED] PC only boots to windows through BIOS

[AwesomeApe]

I can only boot to windows through the BIOS. This is a problem that I have had before and magically fixed, I really don't know how. I just installed a new m.2 Samsung 970 EVO Plus and now the issue is back. So far, I have moved windows and the contents of the 860 EVO SSD to the m.2 and wiped the 860 EVO SSD. This deems it not a storage issue. I have also tried my old PSU so it's not power. The only resolution I have found is removing half of my ram will bring it to boot straight to windows sometimes. However, I feel like this isn't the solution since I'm able to boot windows through the BIOS with all 16GB fine. Any and all help will be greatly appreciated!

Then that is memory issue and has nothing to do with storage devices.

Ok.
First set

DDR voltage to 1.35V,​

DRAM frequency to 2133mhz,​

Command rate to 2T,​

and see, if that resolves booting issue.

If it doesn't help, then increase CL setting to 17, test.
If still the same problem then increase CL to 18 (up to 20) and test again.

After that you may try increasing DRAM frequency to 2400mhz.

It worked. You're a beast. Do you think the ram settings had anything to do with the crashes or is that a whole other issue?

It's possible.
