PC Freeze -> Reboot, BSOD dxkrnl.sys

I did jump immediately to a driver reinstall, which you mentioned that you did. Just to check, did you take the full (somewhat tedious) steps of "uninstall, restart, install from freshly downloaded drivers", or did you install over your existing ones? If the latter, then try the first step. I had a similar issue some time back and had to go full nuke to get my crappy corrupted drivers off the machine. 

If that proves fruitless, i'd run the dxsetup in the BF4 folder again and check that .NET is up to date. Perhaps run a SFC scan, just to be sure.

Sadly i have to say that i did run a clean install of the driver. My friend already made me update my NET framework and the SFC scan i just did gives me the message that there is nothing wrong.

It all kinda started after downloading the last new driver from Nvidia. Right now i installed a newer version again (Still in BETA but wanted to check) and still not solved it.

Thank you for your answer.

I'm starting to fear that it may be hardware/heat related. For that the testing steps are to A: swap in a similar card and see if the same thing happens.

B:The less impractical step of monitoring temperatures. 

Off the top of my head, a step that you have probably tried, and probably won't work, but it's worth checking anyway, is to run either game with a clean boot, just in case. 

I do not own any simililar card here with me so that is gonna be hard to check.

I did already monitor the temperatures while gaming. None of them tend to get in the danger zone. (It is able to check while playing BF4 because that game doesn't reboot my pc everytime.)

Clean boot is something i didnt try yet. I gonna try it right now.

Also, i did buy a new Asus Xonar Phoebus Sound card like 2-3 weeks ago. This caused me to move my Graphic card into another PCI slot. Maybe those 2 things could be it.

Still, why does this only happend with these 2 EA fames running on Frostbite 3? if it would be the sound card or anything i think i should have the problem with a lot more games than those 2.

Thanks again.

I did the clean start. This time i hold it for 20 minutes of gameplay (on NFS Rivals > Crashes quicker and is same error)

After 20 minute, same thing, Screen goes black, about to freeze up but this time it just got me on my background screen (sorry bad english dont know how to call it). And it also said an error > (badly translated from dutch) "Monitor driver program doesnt respond anymore and has been repaired" "NVIDIA windows Kernel mode driver Version 331.93"

BSOD says: Driver caused: dxgkrnl.sys  > krnl = Kernel?

This is getting interesting...

Also a quick question, could this also be caused by the PSU? I own a 860W Corsair one. should be enough, but maybe the graphic card needs some POWER PEAKS. Any way to get more voltage to the Graphic card?

Chuckle, tyvm for following me! i really appreciate it, i hope you will keep following. For now i call it a day. I'll proceed looking to it tomorow.

i found some things that may fix it.

EVGA says to disable the NVIDIA Audio thingy when you have a sound card, it can cause pc freezing and crashing.

Also found a way to change the power the GPU gets from option "Adaptive" to "Maximum"

Gonna try these and leave feedback later.

Excellent, please post if you make any progress. 

Sadly no succes, problem still occurs...
