Issue: PC powering off/reboot during post and boot.

Way back in 2011 I ordered this bundle from Overclockers:

Radon P67 600i Intel 2500K 3.30GHz @ 4.60GHz DDR3 Overclocked Bundle

Which was a Asus P8P67 mobo + RAM, 2500K CPU, and what I think was a Corsair A50 air cooler + fan.

Alongside the above at the moment is a 650W Corsair power supply and two ATI Radeon 7950 cards, 2 SSDs of differing sizes, one 3TB HDD and an old Soundblaster X-Fi of one kind or another.

It's served me incredibly well but over time has acquired a quirk. It used to power off then immediately back on at some point pre or just during POST. This to me was harmless, it booted fine after that and was rock solid.

Since I got it I've replaced the graphics card a few times, and am now running the above mentioned 7950's in crossfire. Since installing the second graphics card there's a bigger problem. The rough sequence of events on power on is now consistently:

1) Power on, during post power off, may or may not immediately power back on.
2) During windows logo powers off, does not power back on.
3) I switch it back on, normal boot (possibly involving chkdsk) and then up and running.

The system is still incredibly stable and doesn't crash once windows is up and running.

Although I'm fairly good with PCs such hardware issues are a bit outside my field of expertise. My first thought was wear and tear on capacitors or power draw during boot. I've monitored how many Watts it draws during power on, post and windows boot and it's quite within my PSU spec even accounting for its age, it doesn't appear to spike significantly as windows loads (maybe another 20watts or so) and it peaks at 160-230watts during boot off the top of my head. Once logged in and running windows for non gaming tasks it's in the mid 200-300watt range. Running a game like The Witcher 3 draws around 400-500watts but never into the 500's.

Does anyone here have any advice for diagnosing this. It'd be nice to fix it so I can keep the PC running as a had me down; however I am looking to upgrade anyway so if the advice is that the motherboard is shot or whatever I'll just upgrade sooner rather than later.

This situation only concerns me now because of power loss during OS load which I'm pretty sure is not good for my SSDs life span!

Thanks,

I've just spotted a similar post about the power off in POST, saying it's normal for Asus boards. Which is reassuring. My problem then remains what to do about the power off situation when the windows logo appears. This is 100% repeatable for me, the first time it reaches the windows logo it powers off.
 
Oops, should've included that in the original post. Still using the ram that I chose with the bundle:

Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (KHX1600C9D3X2K2/8GX)

A bit more google fu has indicated this *may* be a windows issue, so I will hopefully have time tonight to check that out and will update here.
 
The other post about Asus "Reboots" is before the bios fully loads (It checks settings, powers off the psu/mainboard to change power settings and restarts)
It does NOT do mainboard tests while loading the operating system.

Just so you know :)

Yes, but it does explain the one half of what I reported. So it turns out I was right not to be concerned about the initial power on reboot. Now it's just the power off at Windows logo that need concern me. It's re-assuring. :D
 
I may have found something I previously missed in event viewer...

Windows failed fast startup with error status 0xC0000001.

So this appears to be an option you can turn off. For now I will turn it off now and find out tomorrow if everything is better. I think after that I could poke/prod it a bit more and maybe track down what cached system status is causing the crash. I bet it's the graphics personally. :P

This is how I'm doing it, I should probably have mentioned, if I didn't that this is Windows 10 upgraded from Windows 8.1:

1) Control Panel\All Control Panel Items\Power Options
2) "Choose what the power button does"
3) "Change settings that are currently unavailable"
4) Unticked "Turn on fast start-up (recommended)

Well I'll be ....
I had massive issues with fast start when it fast came out on windows 8.1 on a lot Fujitsu machines at work, had forgot about the "Double boot" issue, should have remembered sorry.

Personally I always turn fast start off (Its basically a form of hibernation and I hate anything that sizes big files to my SSD)

When I boot up, I want a nice clean boot up, not yesterdays boot up :P

You are also correct about your original post, I missed the bit about two reboots, my bad!

Glad you sorted it!

Well I won't know until tonight whether it's fixed it. I decided to shutdown the PC and go to sleep. Cold boot this evening will be the real test.

I didn't even know those options existed, it does explain how Windows has been booting so quickly since 7. This type of cached boot process has caused me problems with OSX in the past, but only when integrated with Active Directory logins.
