Twalknz72: Very strange, I just turned his computer on for the first time since lastnight and it went back to the bios. I put the settings back, as the YouTube video, and it's all good again. What's going on?

My stab in the dark, it might be due to the XMP profile.

I assume the BIOS is reverting to the original settings because there is a conflict somewhere.

Easy choices that come to mind are, if it happens again, see if there is another XMP profile i.e 'XMP2', if that doesn't work or there isn't.
Try saving the settings and keep XMP off.
You lose a little bit of performance but better than having to do it for each boot.

I hadn't changed that yet. I did look at it, this morning. It offers "disabled" or "profile 1". I figured just making sure the pc is stable and booting to windows normally was the 1st step then I'd look at the ram settings.

I've restarted it a couple of times since, just the "restart" not proper shut down and wait for an extended period, and it's going directly into windows. I will be keeping an eye on this today and going forward though.

OK so it seems when the computer is shut down by the button or power option it seems to be fine staring up in windows normally the next time. When it's shut down and switched off at the power board that seems to make it start up in the bios the next time. We are trying to be mindful of our power usage so after we turn things off we turn them off at the power board as well, TV, washing machine, microwave all that. So any ideas? If its shut down it shouldn't be drawing power so flicking the power board switch shouldn't be effecting it. I'm really confused.

How old is the computer?

Sounds like you need the CMOS battery replaced.

The computer does continually need a little bit of power to retain the bios settings.
When not plugged in, it uses the battery to power that.

If your battery is flat, and the power gets cut, then that would explain what you are seeing.

It is probably just a standard CR2032 'pill' battery you can get from the Supermarket.

The computer is about 4 years old. We were already doing the flicking off at the power board before we took it in for the windows reinstall and never had this issue. This has only started since we brought it home from the tech. Do you recon it still sounds like the battery?

yep, i would still be changing it as its not normally too hard unless its buried under a M.2 drive or something

I'd put the PC to sleep (S3) rather than turning it off.

If a computer is powered off completely, it then has to cold boot when powered on again, vs warm booting if woken from sleep state. Comparable with cold starting vs warm starting an engine.

Sleep state uses very little power.

Normally it would be the cmos battery, but this issue is on very old motherboards 7-10years or so. Heck my ivy bridge z77 still has its original cmos battery. You can try and replace it but I don’t think it’s the issue.

I reckon it’s either Gigabytes long standing bug with ERP/power load setting (google erp cold boot issue) or the system is not liking a cold boot with 4 dimms of ram. If after a cold boot (power off at wall) it takes a while to start, fans spin for a while, then goes straight to bios; does it bring up a message of any sort?

If you are not enabling XMP speeds for the RAM then try switching the ERP setting and/or power load setting. It should be somewhere under platform power settings.

Btw if the machine is fully off with ERP on then it should reduce draw to basically nothing (<1W). Ideally you shouldn’t keep flicking the back of the switch to the PC all the time, iirc the reason was inrush current to the PSU. Having it shutdown properly is the intended method.

Edit: I forgot, with gigabytes erp/power load bug you’d have to update to latest BIOS from their website to see if they bothered to fix it. If the tech did not already do this then I would suggest looking into updating it if you really want to be able to flip the switch at the wall. Otherwise just leave the mains power on to the PC.

I thought maybe BIOS update, but seems OP already has the latest version (F7).

@OP

Re: CSM

With CSM disabled, the BIOS can only boot from GPT formatted drives (UEFI). Enabling CSM allows MBR formatted drives to be selected as the boot drive (Legacy).

If your M.2 970 Plus disappears with CSM enabled and Legacy only selected, that means it is a GPT formatted drive.

Next to Storage Boot Option Control it appears Legacy only is selected, which could explain why the OS didn't load.....?

but they changed some setting and were able to get into windows, so the question is whats causing it to reset when powered off.

"it’s either Gigabytes long standing bug with ERP/power load setting (google erp cold boot issue) or the system is not liking a cold boot with 4 dimms of ram"

It still only has its original 2x 8gb ram as they said they couldn't use one of the slots as the cooler (cpu one?) was in the way. Not an issue I'm worried about right now though.

"If after a cold boot (power off at wall) it takes a while to start, fans spin for a while, then goes straight to bios; does it bring up a message of any sort?"

Yes it does this and it comes up with the message about setting have changed (sorry it didn't happen this morning as my son forgot to switch off the power board, not the back of the pc, lastnight)

What I do, as per the YouTube video, is enable cms support and choose legacy and legacy again,save and exit. Then Windows loads up no worries.

why do you switch off the power board? try leaving it on and see if you still have the issue, and it will likely confirm the CMOS battery is the issue

Can't say for sure, but my guess is it relates to Cold Boot...? If the CMOS battery was dead, the time/date should reset.

OK so something I didn't think was related before we had windows reinstalled the pc seemed to be loosing time. It's fine now though.

You're right it only seems to load in the bios with cold starts however the cold starts have been happening for the last 3 months. We started being very careful with our power, switching off everything we weren't using at the wall, as costs kept creeping up.

If it is a Cold Boot bug, the boot drive may not be detected in which case restarting the machine normally resolves the issue.

So try the restart button.

I've come across a similar problem with HP systems that occurs when CSM is set to Legacy only and the boot drive is MBR.

When both UEFI and Legacy are selected the problem goes away....worth a shot if restarting doesn't help?

No harm in replacing the CMOS battery though.
