Ryzen 1600x won't POST

So guys, I bought a Ryzen 1600x, MSI Tomahawk Arctic and Corsair Vengeance LED 3200Mhz 16GB RAM.

After receiving it, I set it up with my MSI Gaming X RX 480 8G and my OCZ ZX Gold 850watt. It powered up, all of the LED debug lights came on and then went off. Then the VGA light came on and the screen went from "no signal" to just black. I had this for multiple days, to the point I RMA'd my items with the supplier. They tested it all together, updated my motherboard BIOS to the latest version and sent it back. I set it all up again and same issue, I tested two other graphics cards I had about, one being an old HD 5770 and an R7 260x. I had the same VGA debug light on and no POST beeps. Bear in mind that my previous system is an FX9590, ASUS Sabertooth 990fx and 16GB of Corsair Vengeance RAM. I use the same RX 480, which I bought in January​, and the same PSU and it works fine.

Annoyed, I sent it back to Scan again and said there must be an issue. They tested it, said it worked, took a photo of it at the BIOS setup screen and then sent it back. I have it now and the same issue again. It just gives a black screen with the VGA debug on. I bought a new PSU as the one I was using is severely dated. I bought a Corsair RM650x and it powers up but the same issue. I've even tried some RAM from the QVL being Corsair Vengeance LPX 2400Mhz and still the same. Scan won't replace or refund as it's been opened and they've tested it as fine. I've built around 17 PC's both AMD and Intel and I've never encountered this issue. I'm literally stumped.

As a note, I've been setting it up on a test bench with nothing else plugged in except the RAM, GPU and CPU. I removed the GPU to test the MoBo speaker and I got the one long beep and two short which is a GPU error. So I literally have no idea guys, any help will be greatly appreciated!

  1. try one ram stick in each ram slot see if the cpu or mb ram slots are bad. make sure the mb not shorting out to the test bed. make sure the cpu heat sink not crushing the cpu lid into the chip inside.
  2. in the only video slot lok for bent pins and or dirt. make sure the gpu locked in and check that the slot not broken or weak. see if the gpu moves left or right. sign of broken video slot.
  3. So I've moved it from the test bed to a wooden table to stop any chance of shorting. I've tried one stick from each set in the different slots and I've tried the GPUs in both PCI-E slots. Still nothing. I also removed the AIO and reseated the CPU just to make sure. I didn't tighten it much.
  4. one thing to check is the 8 pin cpu power. make sure your using the cpu power plug and not a video cable power connector. there not the same power plugs both will fit if your not care full. you can see if a local shop can help to see if you made an error. if not see if your credit card can help with charge back. if i was the parts seller i would have asked for all your partd to be sent and built the pc to see if it worked if it did i would sent it back working to you.
  5. Well I only bought the MoBo, RAM and CPU from them. However, I'm gonna slowly rebuild it tomorrow and go through everything. If not I'll take it to my local pc shop and see what they say
