I'm putting together my first high-end PC build after assembling a few low to midrange ones back in 2020, but I'm facing a problem: there's no display. Here are my specs:
- TUF B850 motherboard
- AMD 9900x processor
- 32GB (2x16GB) Vengeance 6400MHz DDR5 RAM
When I power it on, the yellow LED on the motherboard stays lit, the RGB lights turn on, and all the fans, including the radiator's, are spinning. I've checked the CPU socket for damage, and there's no thermal paste on the CPU or the pins. Currently, I'm trying one stick of RAM in the second slot. Any tips on what to do next?

Have you checked what the yellow LED on the motherboard indicates? It could point to a CPU or RAM issue. If that's not clear, maybe swap out the cable to your display or try connecting it differently—like switching between the GPU and motherboard—for troubleshooting.
I did some searching, and it looks like the yellow LED signals a RAM problem. Since it's the first boot, some sources suggest it's just memory training. I’m freaking out a bit because my previous builds would beep for RAM issues, but it's been years since I built one!
