Windows 7: Kernel power 41 reboots while playing, freeze while switching sessions

Kernel power 41 reboots while playing, freeze while switching sessions

Hi Everybody,

It's been a while since I had a pc which perfectly works. In order to resolve the problem myself, I did some stress tests about the components of my PC with AIDA64. All seems pretty ok except when it comes to graphics. When I test my GPU (1920x1080 + Antialiasing 2x MSAA), my pc end up crashing. It doesn't crash when I test it without the antialiasing.

This is an exemple of the Kernel issue :
- <Event xmlns="">
- <System>
<Provider Name="Microsoft-Windows-Kernel-Power" Guid="{331C3B3A-2005-44C2-AC5E-77220C37D6B4}" />
<TimeCreated SystemTime="2015-06-28T20:00:41.339205000Z" />
<Correlation />
<Execution ProcessID="4" ThreadID="8" />
<Security UserID="S-1-5-18" />
- <EventData>
<Data Name="BugcheckCode">0</Data>
<Data Name="BugcheckParameter1">0x0</Data>
<Data Name="BugcheckParameter2">0x0</Data>
<Data Name="BugcheckParameter3">0x0</Data>
<Data Name="BugcheckParameter4">0x0</Data>
<Data Name="SleepInProgress">false</Data>
<Data Name="PowerButtonTimestamp">0</Data>

On the other hand, when I want to switch sessions, my mouse and my Keyboard freeze.

Thanks in Advance,

PS : The logs are in french, I'm here for the translations

Hello, Gktman and welcome to the forums. You do not have any dump files. Please make sure your computer is configured for Small Mini Dumps Dump Files - Configure Windows to Create on BSOD. Are you having actual Blue Screens or is your computer just restarting? An Event ID 41 simply means your computer restarted unexpectedly.

Please reinstall your video drivers using this tutorial and install nothing except the Graphics driver and the PhysX driver NVIDIA Drivers - Avoid Problems

Also, please add to your system specs at the bottom left of your last post, your PSU and CPU cooler. Please also add the Mqnufacturer and Model of the components. It helps us to help you. Having them in your system specs also keeps us from having to go hunt for them.

I noticed a couple of errors from your MSI GamingApp.

Also, please open an elevated command prompt ( click start, type cmd in the search box, right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.

Let us know if any of those helps any at all.

First, thanks for the quick reply.

I did everything you wanted but it's still crashing. By crashing, I mean the computer is rebooting without showing any blue screen. Nevertheless, windows creates a new critical error on the event, which is the same as the one I copied on my previous post; except for the date.

The scannow could not repair the damaged files. I joined the CBS.log

I made the system crash by stressing the GPU but, with the dumps enabled, I can't manage to obtain a dump.
I hope these new information can help.

Thanks again in advance,

Go to Windows Update and in the left column select installed updates and search for KB3022345 and KB3068708. If they are there, uninstall them Windows Update - Uninstall an Update. Watch for them to come back to be installed. Before they install, uncheck them then right click them and select hide.

After you uninstall those updates, run the sfc scan again.

Open an elevated command prompt like you did to run the scan, copy paste this into the command prompt and press enter

findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"
It will put a sfcdetails.txt on your desktop. Right click it and select send to > compressed zip folder. Upload the zip folder here if it is under 8 MB. If it is over 8 MB upload it to One Drive or Dropbox and make it public and I will try to get someone to look at it.

I don't understand but I can stress my GPU gently without making it resulting in a Kernel error... If someone could explain me why, It would be great :P
I'll mark it as solved if It's not crashing for the next days.
Thanks Guys !

Edit: Now windows displays errors by telling me the nvidia driver can't respond
Edit 2 : When I want to stress intensly my GPU, the pc reboots with the Kernal error
