no post Ryzen/B350 - CPU FAIL LED - No Post

[MATRIKZ]

I have just completed a new build with the following hardware:

 

Ryzen 7 1700x

MSI b350M Gaming Pro

G. Skill Flare X 2x8 3200Mhz

Corsair H100i

EVGA 650w BQ Gold+

 

BIOS IS CURRENT

Win 10 Pro 64Bit

 

I'm currently using an old ATI Radeon 4650 GPU while I save money for my 1070.

 

THE ISSUE

 

Upon completing the build, the PC worked perfectly. Bios was updated, MSI drivers (chipset, HD audio, etc.) installed, Windows was installed, played a few games of LoL.

 

The following day I powered down and removed the cables and MOBO to install standoffs on the case. Replaced all cables and powered on.

 

THE MACHINE WONT POST

 

I get a CPU fail light on the MOBO EZ Debug LED

If you suspect it's the CPU, I think the best course of action is just to RMA it under warranty unless you have another way of testing the CPU.

reseat the CPU.

if that doesn't work , RMA the CPU i guess.

How did you have the motherboard set up before installing the standoffs?  I would basically try whatever worked before, otherwise RMA the cpu.

Agreed: it's possible one of the mobo standoffs are not properly screwed or that you have an extra one. It's unlikely that there might be other kind of damage done but I wouldn't discard it either.

Honestly when you try using a Ryzen 7 on one of the worse motherboards of the entire ryzen line up there is my bets are actually on a bad mobo... the socket could be malfunctioning.

I had a similar issue while building custom cables for my rig (see signature). Plugged everything in and got memory issues. Reseated CPU and Waterblock + bacckplate and everything worked fine.

 

Also, the b350 boards are not the greatest, my brothers Asus B350 plus has random boot issues with a ryzen 3 above 3.9GHz. (When it works its stable at 4GHz)
