Overnight boot issues

[Gonio]

Running a 3930K on a MSI x79a-gd65(8d) with 16GB RAM, cooled by a NZXT Kraken x61, GPU is a MSI 680 Twinfrozer III, and a Corsair RM750i as PSU.

 

Allright since a couple of days I have a odd curveball in my system. Overnight I shutdown the PC as allways. I made no system changes for hardware and software. But since a few days when I boot my system it gets in a loop. First a few times the post is just stuck at the first step already giving the 01 code. Then after a few times it posts further and gets stuck on 67 and then again after a few times. It finally startsup with a screen saying its going to default settings completly clearing all bios settings.

 

Iam still in the process of eliminating causes. And sadly I can only replicate this problem once a day. Turning down my PC now doesn't make a difference, all is fine and boots up normally. So it has to be turned of for a long period of time.

First i thought it might be certain bios settings like the OC so last days I ahve been going certain settings default, and for tommorow I will find out if going all the way stock settings besides XMP profile make a difference (but I start to doubt it).

 

However since the whole boot cycle is just taking a few steps to get over it, could it be related to the CMOS battery? Havn't had much experience with that part of troubleshooting, but maybe you all have some ideas about this. Let's say the battery is getting less: normally when a battery gets less you also get less out of a full charge. So that combined with how the boot cycle goes I was thinking that maybe the battery is drained empty overnight, causing this odd boot cycle untill the battery has enough juice to boot up properly. Is this an possible scenario or is this not how it works? If yes, I could try replacing the battery might be a fix then?

 

Other stuff I plan to trouble shoot if tommorow is same story: switching pump connection to other fan header, check cables connections (quick glance didn't reveal anything), take of AIO and test with aircooler. Havn't thought past that yet.

 

Share ideas and thoughts. And thx for the input in advance.

I thought of the battery too. It shouldn't be rechargeable though, so either it acts weird or it's something else. If you can replace it do that and check it again...

[Gonio]

Well I need to get a battery first then. Hope I can find one in store.

It could be the battery is not allowing the Bios keep its current settings.

Do you remove the plug from the wall each night, or does the board still receive power? Reason I ask is because while the board receives power from the wall then the bios will get it's power from the wall as well. The battery is taken out of the mix. So if it is a dead battery, simply keeping your PC plugged in at night will easily tell you if it's the battery of not.

 

It can't harm you to change the battery though, and they are very cheap. Not sure where you live, but In the UK (London) you can get around 10-20 for £1. ($1.30 USD)

Aye. It is powered by the wall still. At first I thought it could not be the battery, because to what I know it's only for time and date etc, so should not be related. But after a bit of googling found certain people that had issues with boot loops and faillure's that despite it not being directly related, was solved by changing the battery. Gonna try it atleast, because going stock settings is also not the solution I found out today.

 

So going to check cabels and connections and reseat everything to be sure, but it still makes no sense. Doubt it's a hardware faillure from the PSU and so far have not gotten the impression to look at something else besides mobo on the hardware part. I  also plan to dissconnect my Kraken, to rule out the cooler itself from being related. In my idea that would be the biggest power drain besides my mouse recharging from USB (assuming there is a powerdrain).

[Gonio]

Bumping this if anyone else has ideas on this matter?

[Gonio]

Battery was indeed issue, got a new one yesterday. So it seems that for this mobo the battery does more then only time and date.

 

Anyway thx for the input from all of you.
