Hi everyone. Been having a strange issue with my first built PC (I am somewhat of a noob at building PC's :D). I built this computer about 6 months ago and up until a few days ago, it worked like a dream.

The specs are:
CPU: Ryzen 5 1600 (never OC'd)
GPU: Zotac GTX 1060 6gb GGDR5 Amp Edition
RAM: 1x 8gb Crucial Ballistix DDR4
Motherboard: MSI B350 PC MATE (Why do I read this in my head in an angry Australian accent? :lol:)

Anyway, the issue is that recently the PC will often refuse to post when booting. It'll also refuse to give a display to the monitor, or power the USB's, so my RGB keyboard for instance would stay unlit. All the fans spin, the hard drive clicks etc. Everything seems to work fine. However, upon opening my case to investigate further, now that I actually have time to, I see that the EZ Debug LED for the CPU stays red the entire time that this happens, and doesn't go off. What I've noticed is sometimes this light won't come on when I press the power button, and the PC will boot and work as per normal, but this is very occasional.

I've researched the problem and tried reseating the RAM, CPU and GPU. None of that worked. I also tried checking if the power supply cables to the motherboard were in properly. This also didn't help fix the issue. I've been told to look for bent pins on the CPU or the motherboard itself, but I'm not sure this would an issue since I haven't removed the CPU since building the PC, and was very careful in installing it in the first place. I genuinely am a bit lost with what to do here. I suspect the motherboard is fried, but am not sure.

Any help would be appreciated. :)
