I started assembling my PC today, but I've run into a couple of issues. After finishing the build, the case fans and RGB lights won't turn on, and my monitors are showing 'no source.' I disassembled the PC and put it back together, double-checking all the DisplayPort cables, but still no video output from either the motherboard or the graphics card, even though the graphics card's RGB lights are lit up. I'm really lost on what to do next! Here's a link to my build: https://uk.pcpartpicker.com/list/FgbhQd. Also, my cable management is a total mess, and I'm not sure I've connected everything correctly. Any advice or help would be greatly appreciated!

When you hit the power button, do any of the fans start spinning? It’s a good sign if the AIO fans and RGB lights come on, but we need to figure out why the case fans aren't activating. It might not be running properly if the system is stuck in standby mode or if the motherboard isn’t receiving a signal from the PSU. Check if all connectors are inserted correctly, especially the 24-pin and CPU power connectors!

Yeah, double-check your connections! If the RGB is on but still no video signal, there might be an issue with the GPU seating or power supply. It could also be worth trying a different video output or port too.
