Weird Shut downs

Rasputini · Mar 27, 2014

Earlier this week my computer started shutting itself off. Not hard shut downs, but actually logging off, spinning wheel, "Windows is Shutting Down" shut downs. It would also happen randomly. Sometimes it was as soon as I reached my desktop, sometimes it was 12 hours later. First instinct was heat. I checked my temps and was between 25-48C depending on the load. I scanned for viruses, nothing. I did a system scan on the RAM, nothing. I watched the power light on the motherboard, it stays on. I checked all my fans, dusted, nothing but cool air. I re-installed Windows and disconnected from my network (in a university campus apartment) and it still would log off and shut down. In fact! I was doing some Windows updates after formatting and it logged out after doing half the installs and gave me the "Windows is configuring updates 30% Do not turn off the power" message before shutting itself down.

Since then it's gotten worse and I can't even get to desktop. It boots, goes to windows login screen, then says "logging off" and shuts down. I thought maybe the SSD was dead. I put it in my laptop and it ran fine for like 3 hours (I went to bed and shut it down properly, so as far as I know it was fine).

Prior to this I checked the Windows event log and found an error that corresponded to the shut downs. It read as a Ntfs error 137 (2) then said "The default transaction resource manager on volume F: (a recovery partition) encountered a non-retryable error and could not start. The data contains the error code." I've since formatted it again and removed that partition but still get the shut downs.

As for what I'm working with:
MOBO: P7P55D-E Pro
CPU; i5-750 (not OC'd)
GPU: MSI GTX760
SSD: Samsung 840 Pro 256GB
2x 1TB HDD (not used for boot)
PSU: Corsair TX 650W
RAM: 8GB Mushkin Silverline Stiletto

Any help or insight would be great!

My brother had this very same issue. How we solved it:

It was an arduous process that lead us to the power supply. More precisely the supply of power (at first). It isn't common for a power cord to go bad, but it happens. We replaced his power cord and the thing ran tiptop for about ten days. Then the problem recurred. The ultimate fix was replacing the power supply. His machine has been fine since. Seems that sometimes when a PSU is betraying its death throws it will require more power than ordinary to run a PC. I suppose that extra draw is what killed the cord, and the fresh cord gave the thing the power to kill itself.

I don't know how new your PSU is. But it couldn't hurt to borrow one from a classmate or coworker to test the theory.

Best of luck to you.

Ya, the PSU is about 4-5 years old. So it wouldn't surprise me. The only reason I didn't think the PSU was the culprit was because the light on the motherboard remains on and the shut down isn't a hard shut down. It actually goes through the power down process. I was thinking of trying to find a PSU to swap in. I hope that's all it is. PSU's are easy (and not TOO expensive) to replace.

Rasputini :

Yes, sir. Let's hope it's that simple. Still, I wish you luck.

I haven't had a chance to try out a new power supply yet as I'd have to buy one. I'm hoping to put that off until I know for sure that's what I need. However, I've checked the event logs and found a couple of things causing the shut downs (I think). Initially I found a USER32 event ID1074 saying "The process C:\Windows\system32\winlogon.exe has initiated the power off of computer (my user name) on behalf of user (me) for the following reason: No title for this reason could be found. Reason code: 0X500ff"

I did some google'ing and found it might be malware. I did some scans and repairs. Nothing really changed. However, each time I put the SSD into my laptop it runs fine. So I don't think it was a virus. I've since done two more spyware and malware scans that showed nothing.

Since the last post I've left my computer off with the panels off. The green power light on the mother board has been on the entire time. Having done the scans, I re-installed Windows again today. I formatted my SSD and deleted all partitions. It had 100mb missing when I formatted it. So I "deleted" the drive and it was full again. I re-installed Windows and just updated. I got a shut down mid-update. I checked the logs and found a "Kernel-power" source with an event ID 109. It says "The kernel power manager has initiated a shutdown transition."

It doesn't come up as an error. It just says "information." I'm assuming this means that it's a software problem and not a hardware problem? The computer knows it's shutting down and logs it as a regular event. Any ideas on what this means/is or how to fix it? Does this just confirm my needing a new PSU?

Sorry, more information:

I've also noticed in the logs that I'll get "DHCPv4 client service is stopped. Shutdown Flag value is 1" I've gotten the same message with DHCPv6 as well. The event code is 50037 for the DCHPv4 and 51047 for DCHPv6

Not sure if this helps. I'm not overly sure what it means. Hope it helps.

Did replacing psu fix it for you? Im having this exact same random shut down issue.

Seems like he solved it with the PSU. Good job!

Kernel power manager has initiated a shutdown - this might come because the motherboard detected incoherent wattages from the PSU. It decided to play safe and shutted the server down.
