Build:
Mainboard: MSI B350 PC MATE
CPU: Ryzen 5 1600
PSU: Corsair TX550M 550W
RAM: 16GB G.Skill RipJaws V DDR4-3200 DIMM CL16 Dual Kit (2x, clocked at 3200 with the A-XMP 2 profile)
GPU: 8GB Palit GeForce GTX 1080 JetStream
SSD: Crucial MX300 525GB
This build was running fine for a month, but now it won't boot. There was no sudden shutdown or freeze before this happened.
The coolers turn on (high RPM), but there is no output to the display, no USB output and no POST (no beeping, no sign of hard drive activity etc.).
Things I've tried:
- Removing the GPU
- Removing the CMOS battery, including pressing down the power switch while it was out (I've tried this a couple times and a couple different ways)
- Trying a single RAM stick at a time, and in different slots
- Connecting a different PSU
- Disconnecting all system fans etc.
- Disconnecting the SSD
This mainboard does have an "EZ Debug LED", which is supposed to signal problems. It always turns on for 1-2 seconds when turning the PC on and then turns off (I believe this is the normal behavior).
The only way I could make a difference is by removing all RAM, in which case the top two lights of the debug LED stay lit (signaling a problem with CPU and RAM, respectively). I'm not sure whether this says anything about the functionality of the mainboard, it at least seems to recognize when there's no RAM, but I don't know how this LED works.
As far as I understand, it's down to the mainboard or the CPU. I don't have any replacement parts for these to switch them out.
- Is there any way I can figure out which one it is?
- Does the debug LED help at all (does it tell me whether the mainboard is still working)?
- Did I miss any other possibilities?
I'd love if someone could help me with this.

but if I had to bet, I would on motherboard.
