MSI B350 Mortar and R7 1700 not posting - CPU debug LED on

My B350's always taken a while to start up, however after my PC went into sleep mode after being alone I was unable to wake it. I restarted the PC and it wouldn't post. It turns on and all fans spin, but the troubleshooting LED remains on and the PC never posts.

 

 

I have since :

  • Flushed the power
  • Disconnected and reconnected the PSU
  • Unplugged everything from the PC
  • Plugged a keyboard back in, and a monitor.
  • Re-seated the CPU
  • Re-seated the RAM
  • Re-seated my GPU
  • Re-seated CMOS battery
  • Shorted the CMOS pins
  • Disconnected all of my fans and rebooted

 

 

I have absolutely no money and work to do so I'm a little panicked here. Does anybody have any suggestions or extra troubleshooting steps to take?

 

Thanks.

Tadgh.

I had the same problem, disconnect all the fans and try to boot if it boots change the fan port to another one. For me is was the cpu fan slot that had a problem

No luck. Interestingly my fanless heatsink isn't getting hot. I wonder if any power is going to the CPU?

I was on default before this I think, and stable. Either way, I've reset CMOS :/
