System freeze/crash - Windows Kernel event ID 41 error

Windows Kernel event ID 41 error "The system has rebooted without cleanly shutting down first" in Windows 8.


This issue recently started on my game rig, and I cannot for the life of me figure out what could be causing it. I strictly monitor my temps. During gaming my CPU cores run 41-50 degrees Celsius. My GTX670s in SLI run 70 degrees Celsius or less, and I am running a Corsair HX1000W power supply, so power is not the issue.

So far this has happened two times, once on 8/27/2013, then again last night, 9/4/2013. On 8/27 my system totally shutdown and rebooted. Last night, my system just froze; everything was still on, just frozen in a still-screen, and I had to hold the power button down to reboot the machine.

Both times I was playing FFXIV: ARR. I built this rig almost a year ago, and game daily on it with no issues until recently.

The only things that are recently different are:
1. Instead of playing Rift, or other games, I am now playing FFXIV: ARR since it just released.
2. I am running several monitoring programs, such as MultiPing, Argus Monitor (paid version), HWMonitorPro (paid version), RealTemp 3.70, Moo0 System Monitor, and Rainmeter.
3. I installed BitDefender 2013 Total Security in lieu of the built in Windows Defender that comes with Windows 8.

My Windows System and Application event logs are totally clean. I have been constantly checking them, with the exception of the Event 41.

My main question is, is there any possibility that running several monitoring programs together could possibly make my machine crash? Again, my logs show no errors, but something has to be causing this, unless it is the FFXIV: ARR game itself.

Any insight or feedback would be much appreciated. Thank you.

I did just find this regarding FFXIV and crashes. I am still reviewing the thread to see if there is anything pertinent.


I am still curious though if running several monitoring programs together could be a problem and potentially freeze or crash my machine?
Looks like a bsod....

Check this folder C:\Windows\minidump

If you have any dmp files then upload it here for analysis.

Hello  EvilPeppard,
could be hard to determin the possible causes, FFXIV: ARR is online right?
so the servers can drop off "currently Full"
That could cause your lockup right there
This page allows you to see which FFXIV servers are online or offline
If I open it in IE 9
Currently fullWorks great in Chrome.
Which browser do you use?
Could relevent as I have seen your error related to flash

I'd like to keep an eye on this question as well see what if any they have to say..
Game lock up in any case would have to point to heat or a lag somewhere enough to cause the system to stop responding, too much activity at once? Reading and writing at the same time with online games.
Bad drivers?
Fan speeds fluctuate on those beautiful GPU's.
Is this windows 8 originally installed on this system to determin if it is hardware or drivers possibly.
Not an upgrade from something else? since you built it yourself.
You said>This issue recently started
Just started to happen could be your SSD.
No dust or anything insode on teh fans on the GPU?
Video card 1: EVGA GTX670 2GB
Video card 2: EVGA GTX670 2GB
SLI: Yes<< never heard of the EVGA brand from what I read they are very good nvidia
I have a Zotac Gigabyte nvidia
Does it come with a tool like my firestorm?
Have you over clocked anything?
What Is SLI & How Can It Improve Gaming Performance?
Kernal mode is interesting with a windows 8.
Architecture of the NT
The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode.

UEFI or legacy bios? <<This could point to drivers?

May I ask if you have taken note how long have you been playing the game when it happens?
Keeping the system running at high speed for 6 hours or more I wonder if the SSD HDD could have a small fit as well with too many background programs writing to it at once?
How much space do you have? Any big temp folders?
Turn of indexing on any SSD if it's enabled.
Check any antivirus you might have installed..Windows 8 doens't actually need a 3rd party AntiVirus software,  but if you do any scheduals to run a scan at a certain time?
 I installed BitDefender 2013 Total Security<<
Do you really need them?
SSD Optimization Tweaks to Increase SSD Performance
Why the backup battery?
Lets say you have a power fluctuation and starts up this
UPS: CyberPower Intelligent LCD Series GreenPower UPS CP1500AVRLCD 1500VA 900W
•The AVR maintains a safe voltage during minor power fluctuations without using the battery,
•Maximum capacity on the CP1500AVRLCD is a powerful 900 Watts / 1500 VA, << 900 watts would not be enough at max capacity to run your 2 video cards? full on game and anything else there?
Just a thought?
You have onboard>Power supply: Corsair HX1000W
No PSU should exceed 65% of max output
Anyway to check if there was a power drop off?

No BSOD, so no minidump files. Sorry, I should have clarified there was no BSOD.

This is what happened each time, as posted initially:

"So far this has happened two times, once on 8/27/2013, then again last night, 9/4/2013. On 8/27 my system totally shutdown and rebooted. Last night, my system just froze; everything was still on, just frozen in a still-screen, and I had to hold the power button down to reboot the machine. "
EvilPeppardAuthor Commented:

I will try to answer all your questions. There are quite a few.


This isn't related to the 'servers full'. Both times this has happened, it happened while I was already in game playing.

Yes, the link you supplied is to my question on another website, DSLReports.com, of which I have been a member for over 10 years.

I use Chrome primarily as a browser.

All my drivers are up to date, unless it ends up being determined there is a problem with the current NVidia 320.49 drivers.

Fan speeds on my GPUs are controlled by the latest version of EVGA PreceisionX, with a custom fan speed profile enabled. Remember, my cards are not exceeding 70 degrees Celsius, and the max operating temperature for GTX670s is 97 degrees Celsius, so I am way under.

Clean install of Windows 8 Pro.

SSD drive shows zero errors in my event logs. Event logs are totally clean; both in Application and System.

I keep our game rigs regularly blown out with an air compressor. No/minimal dust.

EGVA brand NVidia cards rock. They are a great company, with an excellent warranty program. I have used EVGA for close to, if not over, a decade.

Never heard of Firestorm, but I assume it is similar to EVGA's PrecisionX.

I can be in game for several hours before it happens. It has only happened twice, but both times I was in game for at least 3 hours.

The UPS is more than enough to run my system long enough to shut it down. I am not worried about anything else during a power failure. Current estimated run time is 20 minutes with the load I have on the UPS.

Yes, the Corsair HX1000W (1000 watt) power supply is the power supply in my system.
Hello  EvilPeppard
You quoted a Windows Kernel event ID 41 error
any other errors under applications stop errors we could look at
Application (program) events?
System events
event ID 41 error
I see you have response about disabling the monitors.
Let us know if you try that,
In the mean time I did source this
 Borrowed Comment>
hi for those in here check for speed step in bios,
 if enabled try turning off - as i turned off yesterday and to test for shutdown i was playing tf2 (the game that gave random shutdowns) for 3 hours rebooted played again no issues and even booted in to game with out playing overnight with no shutdown if you have intel and have speedstep turn it off

 Edit: so it appears most people on this site have intels if this is true then it would either be c-state or speedstep causing the issue if you guys turn these off and the issue stops happening let us know
If you check the Microsoft article it clearly states that this is a bsod(might show you a diff message in win8)..caused by some unknown driver.


The system has rebooted without cleanly shutting down first

Looks like your system is set for full memory dmp ...config it capture minidmp


Same steps for win8
After that enable verifier by following these steps.

Enable driver verifier
1) Open an elevated command prompt
2) Type "verifier /standard /all"  (no quotes)
3) Reboot your machine
4) Use machine again until it crashes (hopefully this will be fast :)

After the crash... reboot, go into safe mode with networking.  

Disable driver verifier
1) Open an elevated command prompt
2) Type "verifier /reset" (no quotes)
3) Reboot your machine

Upload the minidump C:\Windows\minidump

But my machine NEVER has BSOD'd. And, I have nothing in my minidump folder.

I am very familiar with reviewing the minidump files in the event of a BSOD. I use a program called BlueScreenView: http://www.nirsoft.net/utils/blue_screen_view.html

It is hard for me to consider this a BSOD when it never has happened. I know it has to be something, but based on what I have described so far, and the fact that it only has happened while playing FFXIV: ARR, leads me to believe it is either the game, or somehow temperature related. I am less inclined to believe it is temperature related though, since you can see what my load temps are.
EvilPeppardAuthor Commented:

No other errors to quote from my Event Logs. As I have said, the logs are totally clean. I clear my logs and keep a close eye on them throughout operation of my game rig. I have nothing else going on except normal 'white' log entries.

I do get an occasional yellow, but they are not related to anything serious that I can see.

I did uninstall Rainmeter, and am seeing how that is running. On another forum I subscribe to, someone stated they have had issues like mine with Rainmeter installed and running: http://www.overclockers.com/forums/showpost.php?p=7545185&postcount=2

I also have turned off the majority of my other monitoring software. I now am only running MultiPing, RealTemp 3.7, and Windows Task Manager while I try and troubleshoot this.

Does anyone know if running multiple monitoring programs like Argus Monitor, CPUID Hardward Monitor Pro, Moo0 System Monitor, and others all at the same time would cause any problems since they are all analyzing the system at the same time?

I will look into the Intel Speed Step setting. If that does contribute to the problem, this will definitely be something Square Enix needs to patch for FFXIV: ARR. Remember, I have been gaming 20+ hours per week on this rig since December 2012 in Rift with zero issues.

Thanks again to everyone for all the feedback and ideas so far. Please let me know your thoughts on running multiple monitors together.
Disable overclocking option in bios and then check.

EvilPeppardAuthor Commented:

Are you referring to the Intel Speed Step option in the BIOS when you say to 'disable the overclocking option'?
Not sure  about intel speed step...Check bios for overclocking option....if you see it then disable it.

Just an update. My rig has not crashed for me, but I have only been able to play FFXIV for about an hour or two over the last several days.

FWIW, the thread on FFXIV's official forums has grown to over 16 pages with people experiencing what I am experiencing.

Very good, sounds like it was just too many monitoring tools,
Yes I see with your link,
 they don't know EvilPeppard, I believe they really don't know or won't take a look at it  since it could cost them down time.
This is not an answer just my thoughts..
They are dealing with millions of computers.
It's the same with the question you posted here, their comments don't offer up much at all. But does show they probably have a glitch in the game.
These online Games like Mount and Blade Warband which I play, same thing.
Imagine millions of people using the same game, who knows what is running in the background, who knows what is on their server side where they have the game installed
It may have nothing to do with your awesome system specs but rather glitches in their end.
They can't just shutdown the server to check it either without sending a notice to all users.
So they have beta testers playing these games trying to find the bad scripts / faults to rewrite , then throw out patches with the fixed scripts.
The Background terrains really affect the playback experience from game to game of these types.
 with Mount and Blade/  Warband and Fire and Ice
 I used to rewrite some of the scripts , had to , I'd go into a tavern and I'm standing in the ceiling
 weapons were missing, you'd be on horseback sword in hand fighting the enemy and suddenly the sword disappears and it's down to punching and kicking, quite stressful and funny.
Adding new mods to the games is like adding a new mini game
The worst of this type of issue I found was one new game they released Brytenwalda
It played terribly lockups jaggers lags awful, way too slow so what differs with this game and the others, I believe it is the background.
I'll wait till they patch it

When you know your system more than meets the requirements I'd wait till they patch your game, what you have and what you have done if this show progress no more lockups I understand.
I'd even go as far as disconnecting from the internet disabling security software anti virus. But as it's online you can't.

If your system didn't  meet the requirements then take a little deeper look understanding how a computer functions, it's 100% dependent on electricity if there is the slightest fluctuation, lag anywhere this can cause a momentary pause while the processor determines what it is.
That puts a ? on the Kernel's job.
This can damage everything if the PSU fluctuates.
The  kernel connects the application software to the hardware of a computer
The kernel's primary function is to manage the computer's hardware and resources and allow other programs to run and use these resources,
if your running background monitors as they access the different core part of windows that may deflect the software's attention if you like.
The Kernel says to itself hey what's going on, that momentary interference may have caused the  crash!!!
kernal layouthttp://en.wikipedia.org/wiki/Kernel_(computing)
These days with extra load of high def action games 3D effects
unbelieveable shadings / CGI
 the work our onboard hardware has perform to at lightening speeds as fast as our brains think and fingers can move anticipating and correcting everything is quite incredible.

My issue is not fully resolved at this point, but my system has not crashed since 9/7, although I have only been able to game for 2-3 hours at a time. We'll see how it goes tomorrow, 9/14, since I will be gaming all day; 8-10 hours.
Thank you EvilPeppard
All the Best
