I'm currently building a system for a friend of mine, and came across something very strange.
The system won't post/boot most of the time, but sometimes, it will. I'll add that I'm not touching anything inside in-between booting and non-booting results. I'd say it posts/boots about once every 20-30 times or so. But when it does boot up, everything seems to be perfectly normal. Can get into BIOS, and I even managed to update it to the most recent version thinking it would make a difference, it didn't.
Here are the specs:
CPU: AMD Ryzen 5 1600X + Hyper Evo 212 cooler.
Mobo: MSI X370 Gaming Pro Carbon
RAM: G. Skill Aegis 2400, 2x8GB
SSD: WD Black NVME M.2 256GB
Power: EVGA 650W modular PSU.
GPU: I'm building this with a temporary GPU to set it all up, we will switch for my friend's GTX960, see notes below...
What it does, in details :
Also, I tested this with another Power Supply I had (650W and working as it powers my current PC), and tested this with two different GPUs (older ones, but one Nvidia - GTS450 and one AMD - Radeon 6850). I know they're old but they both work in other systems and since system sometimes boot with both (no difference), I guess those aren't the problem.
Also tested connections through both HDMI and VGA ports. Doesn't make a difference in system behavior. Sometimes boot. Most of time it doesn't.
Now, I highly suspect the RAM may be at fault here, as this kit isn't on MSI's qvl for this board, but the vendor told me there wouldn't be any problem. I was hesitant, but the RAM was on sale and quite cheaper than Kingston or Corsair RAM kits that were on the qvl. Booting with single or dual config for RAM don't change anything. Sometimes boot, but most of the time it doesn't.
Everytime (boot or not) the LEDs light up near the slots when powering on, showing RAM is detected (as per the mobo's manual).
So... anyone got any idea what piece of equipment is wrong here? Does RAM sounds like the culprit here? Or is the board probably at fault? I don't think CPU is bad, as it DOES boot up sometimes and I don't think it would if it was defective. Heck, I don't think anything would work like normal if it was defective... That's what's puzzling me.
Maybe I can get the RAM back to the store as the first step and exchange it for a kit on the qvl list... then if it does the same thing, it'll probably mean it's the board. Right?

GPU: I'm building this with a temporary GPU to set it all up, we will switch for my friend's GTX960, see notes below...
What it does, in details :
■ When powering up, all fans correctly spin. CPU fan, case fans, GPU fans. No problem there, whether it boots or not.
■ When it doesn't boot up, sometimes, CPU Error LED light up on the board. Sometimes RAM Error LED light up too. This isn't always constant. Some said that this could be due to memory, as Ryzen has memory controller on CPU. So plausible. It will stay there, idle, for as long as I don't shut it off. Nothing happens.
■ Like I said previously, it sometimes DOES boot up (approx. 1/30 times), and seems completely normal. CPU detected properly. RAM too, and also read XMP profiles correctly (with latest BIOS).
■ I'm not moving or touching anything between boot tries. Sometimes it work, sometimes it doesn't.
■ I re-seated CPU, RAM, NVME SSD, GPU, checked all power cables and connections... nothing seems physically wrong.

EDIT - yes it does, I remember now, I changed boot order in the BIOS and it kept those settings. Don't remember about other settings, but boot order is still respected (when it does boot).
