I recently replaced my old RAM, which was 2x16GB Corsair Vengeance DDR5 6000, due to some BSOD issues that seemed related to memory. I upgraded to a 32GB Trident Z5 kit, but now my monitor doesn't detect the PC at all. I've double-checked that everything is connected correctly, but I'm still new to building PCs, so I'm worried I might have messed something up. I even tried reinstalling the old RAM, but that didn't help either.

Is your system even posting? Some motherboards have a training phase with new RAM where it takes time to recognize the sticks, which can look like it’s not doing anything for a bit. Sometimes waiting a few minutes can help.
Try booting with just one stick of RAM instead of both, sometimes that can help isolate if one of them is causing the problem.
I tried that too, but still nothing. 🙁
Have you tried using a different monitor to see if that’s the issue? Sometimes it could just be a compatibility thing with the new setup.
Yeah, I tried a different monitor and it didn’t work either. :/
If you haven't already, you might want to test your old RAM again. Also, try using a tool like OCCT to stress-test the memory; if it’s faulty, you can RMA them since most RAM has a lifetime warranty. Have you also tried clearing the CMOS? That can sometimes help with detection issues after a hardware change.
I tried the old RAM, but it didn’t help. I’ve heard about OCCT, but with my monitor not working, I can't use it. Also, I have no idea what clearing CMOS is or how to do it!

It powers on, but then goes into sleep mode. I think it wakes up if I mess with my mouse or keyboard.
