Bit of a strange one...

Hi all,

Just looking into a bit of assistance with the following - I've got a Ryzen 5 2600 Mini ITX rig which consists of the following:

Gigabyte AB350N WIFI
2 x 4GB Corsair DDR4 3000mhz
Zotac 1060 6GB Mini
Corsair SF450 SFX

Today I was installing a new 120mm AIO (experiencing awful temps with stock cooler but no surprise with Mini ITX) & all appeared well up until after powering down after 30 mins of testing in Windows. I decided to change around the pump cable so it goes into another motherboard header in order for it to get full RPM power etc. However, upon boot again - nothing, no post, RGB lights only coming on for a split second before turning off again, and nothing displaying on the monitor. All it was doing was powering up with all of the fans spinning & then the PSU/GPU fans turn off like they normally do after the first few seconds.

I then decided to do the usual things such as clear the CMOS, remove battery, remove both RAM stick & reseat, remove GPU and power via onboard GFX and wait a few minutes again before hooking everything back up... But still nothing

Really racking my brains now, is it possible something on the motherboard could have shorted out? Coming to think of it now, I did feel a slight static sensation on my hand when I first removed the relevant header from the board - and this was 2 minutes after wall plug off & disconnecting the main lead from the PSU.

Any ideas before I attempt to test out another motherboard?

Many thanks - Liam.

Did you try it in original header?

And any kind static disharge when touching PC's internals certainly isn't good thing.
Because of that you should always touch something preferably grounded before touching PC's insides to discharge any static built up from walking, friction of clothing etc.

Very fair points there - and yep I did indeed try the original header, as well as the other one again.

My rig is always situated on my wooden desk when in use or on my wooden living room table when undergoing maintenance / upgrades etc. I'm always very cautious with things such as static and also double check to make sure that everything is switched off / unplugged before disconnecting internals. I suppose it could simply be one of those one in a thousand chances that something like this has happened if this is the case & also a first for me... it also probably doesn't help that my hair can also be somewhat static when I'm about due a hair cut which is about now as well!

I've got a replacement board arriving promptly tomorrow and also a donor Ryzen 5 1600 which I will be testing together first to definitely iron out the motherboard / CPU or both if it's a combined issue... I'm really hoping that worst case scenario it's just the Gigabyte board that has had it & hasn't taken anything else with it like the GPU / SSD!

I also forgot to mention in my original post that the last ditched attempt I did earlier was to completely remove the AIO & re-install the original Ryzen cooler... still no good, fans still spin as normal but I also noticed that the cooler is only pumping out cold air and not warm like it usually should do after the first few seconds. Therefore it looks like the CPU isn't even getting utilised either.

Just a tip: leave the pc plugged in at the wall but switched off when working on it. It leaves the chassis grounded and you can ground yourself on it as often as you like.

Thanks - will remember this for future reference.

All back up & running now with the replacement motherboard (ASRock AB350 Gaming-ITXac) / donor Ryzen 5 1600. Swapped out all the components in minutes and booted straight away upon first power up with the new components. I never attempted to test either the old motherboard together with the donor CPU first / old CPU with the new board first just in case it could be a combination of both or in the event it's a bad board, it could then in turn affect the donor CPU if possible. However my guess in this instance is that the old board is the culprit but both original components are going back to be refunded.

The donor CPU I'm able to keep as well for a bargain as it's an open box but unused that my mate ended up not using for another build, and despite me being on ITX - the stock Wraith Spire cooler is doing a much better job at cooling than what the Wraith Stealth was doing, also despite the Spire being taller & less space to drag in air.

Thanks all - Liam.
