Solved Computer shuts off randomly- not a heating issue

April 16, 2015 at 11:34:57
Specs: Windows 7
My computer has been shutting off (no warning, errors, BSOD etc.) after use for anywhere between instantly after start to a couple hours. My CPU was running hot so I installed a liquid cooling system which now had it down to a steady 40* idle and 45* running some simple processes. My GPU temp is around 28*C which doesn't seem like a problem to me, and I've checked all the voltages which all seem to be within an acceptable range. The connections between the PSU and the motherboard all seem fine as well. I'm stumped. I've checked the event viewer but haven't seen any errors relating to the shutdown. Just a couple DNS errors here and there (I'm on a university wifi and its a stupid set up that has always given me a DNS error). I'm currently using my sporadic time when the computer is working to back up everything on my HD.

Here are my specs:

ASRock 970 Pro3 R2.0
AMD FX-8350
ST500DM002
AMD Radeon HD 7700 Series
G Skill Intl F3-8500CL7-4GBRL 4GB (Single Channel)

Once I've backed everything up I'm going to try to update the BIOS using the update tool right in the BIOS. I know this is risky but I should note that it has never shut down while I was in BIOS or in Safe mode. Its very strange. That being said, I was never in either for long so it may just be that whatever the problem is, it doesn't have enough time to manifest in those modes.

Any and all advice would be SO appreciated. If I can figure out how, I'll post a screenshot of the CPUID HWMonitor that I get.

Gotta feeling that all options are still open. It could be a hardware fault and although software might find it, there is possibility that it will only do so if it happens to fail when the software is testing it.

If it is an intermittent hardware fault then often trial and error is the only way forward. As you are clearly at home within the box then it would be worth cleaning the RAM edge connectors with a soft pencil eraser. You then pop the sticks in and out a few times to clear any oxide off the sockets. Same applies to the edge connectors for any add-on cards. Edge connectors can often cause issues, even though they look good.

Trying one RAM stick at a time in first position might prove something although it will limit use a bit. There is a RAM tester here with a free version:

Have you looked in Event Viewer to see if there is anything showing at the exact time of one of these shut-downs. If so the verbiage might give a clue.

The normal process for updating BIOS is to see if the update was prescribed for the particular issue you are having - in your case shut-downs.

I've tried checking Event Viewer the past couple of days but the only consistent error I see is the DNS one ("There was an error while attempting to read the local hosts files").

I've received a whole bunch more today though, but I'm not sure if they're related since the problem has been around for a few days and these errors only started today. I'll list them anyway though:

DCOM got error "1084" attempting to start the service EventSystem with arguments "" in order to run the server:
{1BE1F766-5536-11D1-B726-00C04FB926AF}

The Computer Browser service depends on the Server service which failed to start because of the following error:
The dependency service or group failed to start.

DCOM got error "1084" attempting to start the service LMIGuardianSvc with arguments "" in order to run the server:
{D4258A22-CF85-489D-83AE-49FCD0DFAD29}

While this one wasn't an "error", just "information", it looks like it might have happened right before it last shut down:

The IPsec Policy Agent service entered the running state.

Right now I'm backing everything up in Safemode (can't believe I didn't think of that earlier). I also figure this will test whether its software or hardware. I've been assuming its hardware but so far it hasn't crashed while in safe-mode which would suggest software. I'll post as soon as it crashes in safe-mode.

I've also run Malewarebites a few times and found a few minor viruses but even isolating those hasn't soled the problem. Must be something else.

If you haven't already done so, disable the auto-restart feature. The next time there's a problem, a BSOD will be displayed instead of the shutdown...then you can research the STOP code & error message.

"My CPU was running hot so I installed a liquid cooling system which now had it down to a steady 40* idle and 45* running some simple processes"

Still seems warm. Definitely not a problem, but my overclocked Phenom idles at about 30C with air cooling. Did you goop on too much thermal paste?

"I'm going to try to update the BIOS"

Do you know which version you currently have? The 1st version was 1.00, the latest is 1.80. Most of the updates address memory & CPU support. It certainly won't hurt, provided you do it correctly. Here's what v1.80 "fixes":

1.Improve CPU compatibility.
2.Improve DRAM compatibility.
3.Support secure boot for AM3 CPU
** Plus it has all the updates contained in v1.10 thru v1.70.

How do I disable the auto-restart feature? That would actually be very helpful.

As for the cooling, I'm really not that worried about it. I'm in a house without air conditioning, and its pretty warm already. My CPU before I updated the cooling was running at about 65* and that scared me so 38-45* seems great.

Also- update- I'm still backing up my files in safe-mode and haven't had a shut-down. It definitely seems like a virus or corrupted software issue.

The BIOS update will be my very last resort. Once I'm done backing up I'll try a system restore to last week and then RogueKiller. Then I'll probably leave it on overnight to see if it shuts off. If it does, I'll be back on here for advice!

In answer to your #2 (as I raised it) is that nothing there stood out as a reason for the computer to suddenly shut down. The one that "entered the running state" would have been on boot up, not shut-down. You could always temporarily disable the LogMeIn service (LMIGuardianSvc) just to see if it helps, as it is non-essential to the basic running of Windows.

Otherwise I would run with Johnw and eliminate malicious activity from the equation.

Was able to back-up my files and during that entire time in safe-mode (about 4-5 hours) it never shut down. I think its definitely safe to say its not hardware.

Attempted a system restore from safe-mode (to 8 days ago, before this problem started) and it became stuck at the Initializing stage (blue circle was turning, but nothing else was happening). Restarted with the power button. Instead used F8 to enter a clean boot and System Restore from there. It shut off at the initializing stage. I let it restart and again used F8 to enter clean boot and started a system restore. This time it got to the restoring files stage before the computer froze (completely). On the fourth attempt it shut down at the restoring files stage.

At this point I'm letting it sit as I've found that it sometimes lasts longer after its been sitting for an hour or so. I'm finding it very weird though that the symptom (shutting off) persists after a clean boot into system repair.

I'm going to try restore one more time and if that doesn't work I'll skip the restore and go straight to RogueKiller.

Any ideas?

Finally was able to get the computer to go through the full restore, however I received this error:

"System Restore did not complete successfully. Your computer's system files and settings were not changed.

Details:
System Restore failed to extract the file (D:\Program Files (x86)\Hi-Rez Studios\HiRezGames\smite\Binaries\Win32\cudart32_41_22.dll) fromthe restore point.
The restore point was damaged or was deleted during the restore.

You can try System Restore again and choose a different restore point. If you continue to see this error, you can try an advanced method. For more information, see What is Recovery?"

I honestly was surprised it gave me that restore point in the first place as I don't ever remember turning on the system restore function. Guess I was right.

On to the next step I ran RogueKiller. Followed the instructions and this is the log:

I will also point out that these are the only processes running on the machine on start-up:

dwm.exe
taskhost.exe
explorer.exe
winlogon.exe
atieclxx.exe
taskmgr.exe
csrss.exe

I left it with only that running and it still shut off after less than an hour.
On the other hand, the processes running in safe-mode (which doesn't shut off) are:

explorer.exe
taskmgr.exe
winlogon.exe
csrss.exe
ctfmon.exe

I also checked the Event Viewer and there's nothing within 5 minutes of the shut-down, but there is the following error at least acknowledging it:

"The previous system shutdown at 11:31:53 PM on 4/16/2015 was unexpected."

I've also started receiving a whole host of errors on start up. Here they are for you, although I'm not sure if they're relevant:

How do you measure CPU temps? Socket/package temp?
If you have 8 cores there should be 8 temps visible.
I can't find max CPU temps from AMD website. Very strange to me.

Look for AMD CPU stress test app. I don't use AMD, perhaps other members know.

I had problems of restarts and it was because of heat problems. Idle temps were around 50 C. (living in the tropics with environment temps ranging from 25 to 36 C & high humidity).
If a ran a program with moderate load CORE temps spike up to 80 C. I'm sure the protection kicked in and lowered clock or inserts NOP states but sometimes shutdown/restart happened.

After cleaning out the box, including removing the CPU cooler and "washing" the black dust (from the pollution) clogging the cooler-fins, apply new paste etc. , all runs fine again. This has become a yearly tasjk.
Using an INTEL CPU stress test program, it checks out the CPU including a 4 (or longer) minute stress test loading all cores 100%. Measured CORE temp are reported 25C below maximum at this moment. ( I see the CORES hovering around 83C.)

Another possible contributor was the internal Sony DVD-writer (SATA) that after 1 year started to make trouble; not reading/writing DVD even problems working with CD's. It slowed down EXPLORER trying to read discs up to a no response state for long times.
Disconnected the device and now use an USB external DVD writer. (easy to share with other PC's & laptops).

I'm really not sure its a temperature issue. My CPU sits at a solid 8C (47F) just using Chrome. I don't see that as too hot unless I'm totally confused about temperatures.

As for the stress test, I'm not sure how those work, how safe they etc. so having some input from someone with an AMD would be great.

In any case I treat this computer like a temple. I clean all the fans and entire case out once a month. It sits out from the wall etc.

I still find it really weird that it crashes in the clean boot menu and on regular boot but not in safe-mode. There's something there I'm not getting.

Possibly found a solution for the errors listed in #18.

I deleted the file "C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst" and from what I've researched the service will create another uncorrupted file on start-up which should solve the issue.

I'll check next time it shuts down to make sure that error is gone.

I'm scraping the barrel personally but:

Better double check that the auto-restart setting is still set to disabled.

Did you try temporarily disabling LogMeIn (LMIGuardianSvc) service (#8)?

There were some questions & comments raised by sluc at #12 which might be worth reviewing.

Did you try the suggestions in the last paragraph of #15?

Not sure about Lazesoft "other options" (#16) - Johnw will no doubt comment in due course.

Type msconfig in the Run box and disable non-Microsoft items in Startup to see if doing so cures the symptoms. If so it would then be easy to find the culprit.

Not so sure about the loss of power idea but when this happens intermittently it is mostly down to poor connections. Wiggling connections or even tapping around inside with an insulated prod can often unearth them (known as vibration testing). Also make sure that moving the power cord plug doesn't cause it to shut down.

"Better double check that the auto-restart setting is still set to disabled."

It definitely is.

"Did you try temporarily disabling LogMeIn (LMIGuardianSvc) service (#8)?"

I've disabled it from start-up but to be honest I can still see it running under all users in when i boot up task manager. Would you be able to tell me how to disable it for all users? (I'm the only user but it still runs processes not under my user for somereason)

"There were some questions & comments raised by sluc at #12 which might be worth reviewing."

My CPU temp is at 9C and my GPU is around 27C. Neither of those raise a red flag, and the computer has all been clean. I'm not sure about stress tests as I'm worried about damaging the CPU so I'd to hear from someone with experience with AMD.

"Type msconfig in the Run box and disable non-Microsoft items in Startup to see if doing so cures the symptoms. If so it would then be easy to find the culprit."

I've disabled all non-Microsoft services. I did this once before and it didn't solves the issue but I'll let you know if it does this time.

I'm going to try moving it around to different outlets. Maybe it the outlet that's causing a loss of power? I dunno.. I'm feeling pretty defeated. I'm gonna fix it thought. If I have to wipe my entire HD I will get it working again.

To disable a service just type services in search - best not use msconfig for this. It should show before you finish typing. Click on it and you will see a list of services, so you need to look for LogMeIn or LMIGuardianSvc - not certain because it is not a standard Windows item. When you find it double click it and a Window will appear. Hit the Stop button first then from the drop down choose Disable. Note what it was set at before you start (probably Automatic) so that you can restore it later if you require it.

If all else fails I will take it into a shop. I really can't afford it, but I also can't afford not having a functioning computer. If you guys come up with any ideas over the weekend PLEASE let me know.

Cheers.

Hey guys. So here's the final result.

I have not found a solution to the problem. I ran memtest through 4 passes with no errors. I have installed all of the Windows updates. I've moved the computer to different outlets and raised it from the floor via cardboard (at one point I wondered if static from the carpet was short-circuiting the MB). I've run all the windows repair software I could find and disabled all services I could upon start-up. Within two hours it still does one of three things: shuts off, BSOD or freezes entirely (have to force re-start).

So I've given up. I'm going to do what I probably should have done ages ago and back-up everything I have, wipe the HD and re-install Windows 7 fresh. Before I do that I'm going to try once to use the 'Upgrade' options given when you boot from a Windows installation disk and see if that helps, but ultimately I'm just going to use DBAN and start over. It sucks.

Thanks for your help- I'll post one final update once all the re-installs are done, provided that there are no problems with that.

Cheers guys.

No need to use DBAN, just use your W7 install disk & make sure you Delete all partitions & then Format.

Make sure when you reinstall, you delete ALL partitions & format.
W7 - Click on > Drive options (advanced) Then highlight each partition & hit > Delete.

Here are some examples of why you delete all partitions.

Sometimes it just too hard to track problems down.

Make sure you if a reinstall is the way forward, you do your testing in small steps.
In other words, trial just a basic install for a period of time.

This solution has been long in coming.

I left the country for work and in the meantime left my computer at a local service place for the three weeks I was away. They replaced each part of the computer one by one and finally decided that it was an issue with the USB 3.0 on the motherboard. Do I believe it? Not sure. I've had it running without issue since yesterday so I'm really hoping that my new motherboard has solved all the issues I was having.

Thanks for all your help.

Cheers.

Glad to hear you got it fixed - pity you had to pay. With hardware faults it's easier if you have spares to hand, so if it gets desperate you can do swaps to find the culprit.

Always pop back and let us know the outcome - thanks
