BSOD, Bug Check Code c5, ntoskrnl.exe

[DoctorFalken]

Hello Seven Forum,

First I´ve read the " Blue Screen of Death (BSOD) Posting Instructions" and the zip file is attached

Now to the nasty BSOD - Error:

The PC is running stable except on Program , I only get the c5 error when using one specific function from a Program called Unity(ver 4.6.9f1) this is a function for baking lightmaps, when called, this function will start Beast(a programm from Autodesk to bake lightmaps) and then while baking the BSOD appears. The Program it self seems to be stable too except that function.


What I´ve done so far:

• Checked CPU heat with HW Monitor - Not to Hot
• Checked System pressure with PCMark 8 & HeavyLoad x64 - No Crash
• Installed latest MS Updates
• Installed lates Nvidia Driver
• AV Scanner is MSE
• No tools like CCleaner installed
• Run MemX86 test for several Hours - No Errors

Sys Info:
W7 Pro 64-bit (6.1, Build 7601) Service Pack 1
i7 4771
NV GTX 760
8GB Ram
Gigabyte GA-Z87-D3H

So I hope the infos are what is needed to narrow the issue down,
Thanks in advance Dr. Falken

Run Display Driver Uninstaller(DDU)
Make sure you tick the Uninstall C:/AMD and C:/NIVIDA folders while you are in DDU when you are done running DDU install your graphics driver again.! This is the guide for DDU: http://www.sevenforums.com/tutorials/367109-display-driver-uninstaller-how-use.html

Open your startmenu and search for verifier.exe. Now click on the create custom settings(for code developers) option and click next. Now click on select individual settings from a full list and click enter. Now make sure you check the "Special Pool" option and the "Pool tracking" option. After that click next and next again. When you are at the last page click on the "Automatically select all drivers installed on this computer" option and click next. Now restart your computer and let Driver Verifier run for 24 hours.

Run Furmark, if the temps goes too high stop the test. http://www.sevenforums.com/tutorials/100356-video-card-stress-test-furmark.html

FurMark was running three times for at least an entire hour every instance. It was not to hot(not beyond 80°C) nor it produced visible artifacts.

Any idea what to do now?
