I received my Dell Inspiron i7559-7512GRY on December 16th. The laptop operated perfectly until January 5th, when it simply stopped booting into windows. If I allowed it to sit long enough, I would eventually get a Blue Screen indicating a DPC_WATCHDOG_VIOLATION. Windows did load on Safe Mode.
I started trying to correct the issue with a system with a factory reset – first keeping files, then I tried again without preserving my files. I then tried a fresh install of Win 10. All of these had the exact same issue when windows tried to load. Since Safe Mode worked, I started disabling devices one at a time until I narrowed it down to the nVIDIA GTX 960M video card.
When the nVIDIA Video Card is disabled in Device Manager, Windows can load. The second I enable the video card, the computer becomes rapidly less responsive and soon crashes with the Blue Screen mentioned above.
I tried a fresh install of the nVIDIA device driver to what came from the factory – this did nothing.
I tried updating the driver from Nvidia’s website to get the latest version – again no results.
I have updated the BIOS, and all other drivers on the system – the same problem persists.
When the nVIDIA card is enabled, the system just can’t run.
I'm running an extended hardware diagnostic on the system now (should be complete in ~3 hours).
If anyone else has had this issue, I’d appreciate help. But I’m starting to think this is going to be a warranty case …
Solved! Go to Solution.
I made my warranty valid and the technician told me he had to replace the motherboard. He said that it is the only solution to this problem because the Nvidia GPU can't be replaced because it is integrated in the motherboard(I think it's possible but some special tools and skills might be needed).
Fortunately, Dell was very fast applying the warranty. I opened a case sending a mail(it can be done trough chat) and they asked me to give them some screenshots of the problem and of the ePSA (BIOS test). After that, they created a depatch order, I took the laptop to the workshop they told me and after a week the computer was ready.
The info they asked me can be found here: https://drive.google.com/drive/folders/0BwhFAJy2mRJwZnNzVy0yQTZRR28?usp=sharing
It sounds sad, but that's the point. The only way to fix it it's changing the motherboard and I think it's better to buy another laptop because a refurbished motherboard costs around $400, so it's worthless.
Same thing is happening to me. I think it must be Nvidia. I thought it was my RAM at first, it wasn't working so well, I replaced it, still had the issue. I even re-installed the OS.
I don't think it's the OS fault or Dell's, must be the driver. I guess

Reinstall the Dell driver for the video. That one is customized for your model's motherboard. Since this is a 3 week old computer, contact Support asap if you can't correct the problem.
I'll check this out right when the diagnostic completes. And yes, I'll definitely be contacting support (partially why I'm on here). Appreciate the link Mary G!
Tried the suggestion with the SATA AHCI driver, but sadly no change. The moment I installed the nVIDIA driver, my laptop crashed.
I've tried all the current drivers Dell has on the website (as of January 9th ... today), and even tried the most current driver from nVIDIA after the SATA AHCI change. No Luck.
Note I also ran the complete hardware diagnostic, but I noticed that it only checks the integrated Intel video chipset. It doesn't mention checking the nVIDIA card at all. Seems kinda useless...
If there's a Dell representative that sees this, I'm gonna need additional help please.
I have got the exact same problem! Have done everything you mentioned, and had Dell Technician remote access my laptop and do all the diagnostics and update Aug 2016 NVIDIA driver on Dell Website. Nothing helped. The Technician asked me to send it for a repair. Maybe a motherboard replacement is needed. How is yours by the way? Hope you reply!
Same issue here. My plan is to enter geforce website download every driver i can find for the gtx 960m start installing and uninstalling one by one to i find what works
I've been having exactly the same issues as yourself with my 7559 and have tried everything you have done yourself, as well a few other things all to no avail. Have you made anyway headway with yours? For reference, mine crashes anywhere from once every few weeks to as many times as I am willing to reboot it in a day.
Unfortunately, I am facing exactly the same problem and I have tried all those procedures you tried too.
Could you solve it? Did you made use of the warranty? If you used the warranty, did they change any part or what did they do?
Any update on this thread? I got the exact problem.
Any dell support who can help?
Already tried all the possible solution i found online. But still the same
And this thread seems to be unresolved.
