Possible Power Issue

[OolongGoat]

I have updated my specs in my profile......

Since installing Windows 10 I have had a weird issue with my PC. When I power on my PC after it being off for a few hours it will turn on.... then 5-10 seconds later power off and stay that way. When I press the power button again it will turn on and then boot into Windows normally. I have looked in my BIOS for maybe a setting that is causing it but I haven't touched the BIOS since I updated it back last year with the latest version... F10.

Since I have been having issues with the graphics/monitor I am thinking maybe the graphics card might have something to do with this....

I have a 1200W PC Power and Cooling Platinum PSU.... I have had it for about.... 4-5 years now I suppose since I had the Water Cooling and SLI 570's.....

Since I don't have all the fans, pump, and two graphics cards, I would suspect the load should have eased up on it....

I did enable the Dummy Load in the BIOS in the event on power up there wasn't sufficient load as to cause the PSU to turn off.... I don't have any power saving running as my CPU is OC'd to 4.0ghz and everything else is left on AUTO. All I touched was the multiplier.... it has been running like this for almost 3 years now.....

Could Windows 10 have changed something? I would not think that given the system powers off before POST but who knows... I know Gigabyte boards have that POST test they do before turning on.... this board used to do that but hasn't recently as I recall.

looks like psu symptoms or motherboard

btw what happen to your vga card?

I have a prior post about the signal between my vga card and monitor getting corrupted. One of my DisplayPorts is bad.

I have a similar problem. After upgrading to Win10, when my PC has been off for a day, I can turn PC on and it boots and starts to load Windows, then freezes while windows loading screen circle is running. After pressing restart button, it boots and loads windows normally. I have not figured it out yet, just sharing my experience.

Did either/both of you upgrade from windows 7?

This was a clean install for me. Maybe it is related to new windows voltage management?

@Swamp Monster that is very interesting...... I did an upgrade from Windows 8.1 to Windows 10......

So I have been messing with this awhile now.... I updated the BIOS of my motherboard..... no change. I turned off all the C-States, EIST, C1E, and it is still having this behavior. I bumped my Vcore to 1.165V. It was at 0.7-0.8V on idle which I assume is due to the dynamic voltage.... under load it was around 1.145V-1.150V. So after all of the above it is still doing this behavior.... I even enabled the dummy power supply load in the BIOS thinking that maybe there wasn't enough load at startup to keep the PSU on... but then it wouldn't make sense that it turns off immediately on the first try and then POSTs on the 2nd attempt.

I would like to think Windows 10 is the cause but after this... it is not even getting to Windows so I am more inclined to go with PSU or Motherboard.... the PSU is about 4 years old at this point but has a 7-year warranty..... The motherboard I have about 6 months left on that....

try disabling fast boot ....
the behavior you are describing sounds like standard cold boot behavior after a ac power loss
could be the stand by power on the psu is flakey
there are various things that will cause a double post
1. loss of ac power
2. the board needs to post twice to apply some settings
3. failing cmos battery

I upgraded my main machine (4970k machine listed in specs) from 8.1 to 10 a few weeks back on a Saturday morning. The following day I powered up my machine in the morning and a few minutes in the machine just powered down and restarted itself after a few seconds.

Upon restarting it would always go the the screen asking to reset my bios to default settings. After going into the bios and checking my settings I exited and the machine would start up fine and stay on all day long. This would occur everyday when I'd get home from work and after a couple of days it seemed like it would always happen at the exact same time after startup.

So I decided to start running a timer to see if my suspicions were correct, which it turned out they were! Every time it would shutdown > restart at 10 mins and xx seconds. I checked the even viewer for any critical errors and found the same one for each day (can't recall the exact name as it's no longer on the log) but was something to do with event 41 power-kernel.

Researching this lead to a few posts about dirty shutdowns in windows 10 as well as a couple dealing with 8.1. The one suggestion I found from one of the 8.1 posts said that to turn off "Turn on fast startup" under power options. After I did this I haven't had a single shutdown since.

I'm not sure if this is at all related to your issues, but it's a simple thing to try just in case it is similar to the issues I was having since upgrading to 10.

Good luck!

I believe that fixed the issues I have been having. That is very good find and informative. Might be worth making a sticky
