Nvidia GTX 850M causing DPC Watchdog Violation when playing games - Windows 8.1 x64

[RockSide]

Hi guys,


After spending more than 3 days unsuccessfully trying to resolve this problem, I am completely frustrated and need some help.


I have a Laptop ASUS N550JK, with the following specs:


Intel Core i7 4700H
16 GB RAM
Graphic cards: Intel 4600 and Nvidia GTX 850M.
SSD Samsung EVO 250 GB
Windows 8.1 x64 Professional


Basically, if I try to play any game (League of Legends, Counter Strike GO, Just Cause 2, etc) using my NVIDIA card, after some seconds the Windows freezes completely and I get a BSOD with the message DPC_WATCHDOG_VIOLATION. If I remove the driver, and play these games using the Intel card, everything goes well. Sometimes, I get a "Nvidia driver stopped responding and has recovered".


I already tried the following solutions, but without success


* Did fresh install of Windows 7, 8, and 8.1.
* Installed the Intel/ NVIDIA drivers from the Asus website; install the video drivers from the Intel and NVIDIA's websites, install old drivers.


I also did a DDU of these drivers, no difference.


* Removed all antivirus software, unnecessary softwares, etc.
* Updated the BIOS.
* Replaced the SSD by other HDD and did fresh install of Windows, drivers, etc.
* Tried to keep only one RAM stick, both, etc. Also ran memtest86 and no errors were found.
* Tried to run the "driver verified" and it did not get any error until I run and game and break the system.




Curiously, I ran some gpu stress tests (OCCT, vmt, memtestCL) and I did not get any error.




Does anyone have any thought about why this problem is happening? What should I do?


Thank you so much for your help.


PS. I am also sending the last minidumps after the BSOD: https://www.dropbox.com/sh/c21mhbcv4bzly74/AADtQ5bppPViGhCTLs-lX8MTa?dl=0

Just some pictures about the freezing moments (before the DPC_WATCHDOG_VIOLATION BSOD):

1) Counter Strike GO



2) League of Legends



3) "Driver stopped resposing..."

Have you verified your fan and heatsink are clean and that the cool air intakes are clear?

I assume you are not overclocking or undervolting?

Thanks for your answer.

Well, I opened the laptop yesterday and all fans looked well and clean. I did not change anything related to overclock in the BIOS (I think I can't do this, anyway). Also, the Counter Strike GO game freezes at the main menu (without any load).

Today, I did a new stress test and it looks like the temperature is OK (look at the bottom):

Remove the video card and use either a secondary or onboard for testing.

I forgot to mention in my first post that if I remove the NVIDIA driver and play the games only with the Intel Graphic card, I don't have any problem.

Your video card is the problem, then.

Well, I will open a RMA and send it back to Asus. :frown6:
