Hey so I’ve recently just got all comments for my custom build put together.
Motherboard- Msi MPG X570 Gaming edge WiFi
Gpu- GeForce RTX
Cpu-AMD Ryzen 7 3700x
Ram- Corsair Vengeance Lpx 3.6 Mghz
Case- NZXT H510i
PSU-Corsair CX750M 80 Plus Bronze
Hard Drive- Barracuda 2TB internal hard drive
The main issue that now come is that there is no power going to any of the USB ports. As well, the DRAM debug light stays on. It all powers up fine but there isn’t anything going to the monitor display. All plugs seems all plugged in on the motherboard. Any help would be much appreciated.
