Inspiron 7559 Blue-Screens when nVIDIA GTX 960M is enabled.

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 …

Wondering if anyone has had any luck resolving this problem, either through contacting Dell or otherwise.

I have recently started haviing this problem after nearly a year of the laptop working fine.  Windows 10 will simply not boot no matter what I try unless I boot into safe mode.  In safe mode, I can go to the device manager and disable the 960M, at which point I can boot normally and the operating system will function properly.  If I enable the device  the laptop will quickly lock up and then I will have to reboot and it will not boot again until I go to safe mode and disable the device again.

I have tried updating the driver but when installing the driver it automatically enables the card which causes the freeze/cannot boot cycle again.

Hello! I have the same problem, the blue screen appears when loading os. I boot into the safe mode, turn off nvida 960m and only so you can use your laptop. We need help in solving this problem. How to rightly contact support to help me?

Did they charged you anything?

My PC is still on warranty so Dell took in charge of all expenses. Actually, I have had the same problem twice, and both of them they finish replacing the motherboard. The second time, they changed RAM and HDD to see if those parts could be part of the problem, but in the report said that none of these helped to fix the problem, so they had to change the motherboard (for me was obvious but they insisted that wasn't the dedicated GPU).

I recommend you to use the warranty in case it still been valid.

The best thing would be that they detect what it's making the GPU  to get damaged, so we can make something to prevent it.

If anyone wants to know more about this, just ask and I will answer as soon as I can.

Good luck!

Glad for you to still have the warranty.

I used to use Ubuntu, which means the Nvidia card never worked at all and after switching to Windows, I never had a chance to use it due to the bug in this post. So basically, my Nvidia card have never been used, I don't think there was a chance to damage it.

I think it's still a driver or os problem.

Actually, NVIDIA provides a driver for Linux . I haven't tried it now, but the first time this problem occurred, I installed Linux and downloaded the driver and when I tried to install it, the OS crashed too.

I disagree with you in that point. How is possible that it works with the same Driver and OS after they changed the motherboard? In my opinion, it can be related to refrigeration, but in both occasions, the dedicated GPU wasn't even been used, I was using office and had some IDE's opened (nothing heavy). Now, if we talk about firmware instead of drivers, I support your opinion. Dell's firmware might not be well, but all this are just opinions and not facts.

The drivers won't work, I have tried every possible way.

I think I haven't got your point. I never changed the motherboard but I still have this problem. If it's a hardware damage problem, it should be fixed as soon as they replaced the motherboard.

I agree with you that it's probably a firmware problem. Actually I have no idea where does this problem come from, I just think the chance of a hardware problem is small instinctively.

Yeah, sorry. What I wanted to write was:

"How is possible that it works with the same Driver and OS after they changed the motherboard?"

I think that you'll get my point now.

I tried every solution on Linux, it won't work. It's well known that Linux support for hybrid graphic cards ***, even the support from Nvidia said so.

I am not sure if I get your point. I never changed the motherboard but I still have the problem. I think if it's due to hardware damage, the problem should be fixed after a hardware substitution.

I agree with you that probably it's a firmware problem, actually I have no idea what is the problem, I just think the chance of a hardware bug is small instinctively.

Thanks, I can understand now.

I think it means it's hopeless to solve the problem now since my warranty has been depleted.

I don't usually play games, so I think it's not a big deal for me  to have a dysfunctional nvidia card. But I am still disappointed by Dell, they should not ship a product which has such kind of problem and the quality control is worrisome.
