I just put together a new PC, but I'm facing an issue where it won't output any video. The DRAM light remains on, and I'm not sure what's wrong. I've tried two different sets of RAM; the first wasn't on the motherboard's approved list, so I switched it out thinking that was the issue, but it hasn't helped. Here are my specs: Motherboard: ASUS ROG STRIX Z890-A (LGA 1851), CPU: Intel Core Ultra 7 265KF, Memory: CORSAIR VENGEANCE RGB DDR5 RAM (32GB total, 2x16GB, 6400MHz), GPU: ASUS Prime GeForce RTX 5070, and PSU: Rosewill VMG 1000W 80+ Gold. Any advice would be much appreciated!

Don't forget to clear the CMOS. It's a crucial step and can often resolve boot issues like this.
If your motherboard has a BIOS flash button, maybe try updating the BIOS? Sometimes a newer version can fix compatibility issues.
I did try that already, hoping the new BIOS would work with my first set of RAM, but no luck.
Have you tried using just one stick of RAM in the A2 slot? If it doesn’t boot, switch to the other stick and try again. Sometimes, starting with one stick can help isolate the issue.
I tried both sticks in A2, but unfortunately, it still doesn't boot. The orange DRAM LED stays on.

I've cleared the CMOS multiple times. It's become part of my routine before making any adjustments.
