Flashing between DRAM and CPU

[sjabini]

I have a custom built system that keeps on failing when I go past the BIOS. I first started out with a MSI X570 A-Pro Motherboard which allowed me to boot into Bios, and even run a memtest86+ without a problem. As soon as I get past the BIOS and try to install an OS with will fail after a minute or so. I get the debug lights flashing between CPU and DRAM.

 

These are the things I tried.

1. Checked the pins on the CPU if they are bent
2. I tried using different memory slots with just one memory module.
3. Changed Power supplies
4. Tried to install both Windows and Ubuntu
5. I thought it was a bad motherboard so I replaced it with a B450 Aorus Pro WiFi (Rev 1.0 )

 

Build List:

CPU: AMD Ryzen 7 2700X 

RAM: Corsair Vengeance LPX 16GB (2 X 8GB) DDR4 32000

Mobo: B450 Aorus Pro Wifi (Rev 1.0)

HDD: Samsung 970 Evo Plus 500 GB

Graphics: ATI Radeon 256MB PCI-E 7120036200G Video Graphics Card Cedar (test)

Case: Fractal Design Focus G

PSU: Corsair RM850X

 

**UPDATE

I replaced it with a 3000G CPU and everything is working well. I just RMA'd the 2700X

I tried using one module at a time. I've only tried one other memory module.

The original graphics card was a MSI GTX 760.

It didn't. I'll try a different CPU when I get a chance.
