BSOD CRITICAL_PROCESS_DIED and UNEXPECTED_STORE_EXCEPTION, ntoskrnl.exe

System Information/Dumps
I'm not entirely sure if this link work, so I've supplied some basic system information below for context.

- Samsung model 940Z5L
- x64-based PC
- Intel Core i7-6700HQ @ 2.6 Ghz, 4 cores
- Windows 10
- Nvidia 950m

I have been having these BSOD's for quite some time now. I have done:
- sfc /scannow, which comes up clean
- chkdsk, comes up clean
- Seatools, comes up clean
- dism /online /checkhealth, comes up clean
- Windows memory diagnostic and memtest, comes up clean
- updated drivers, I believe all of them but I may have missed some
- uninstalling and reinstalling my graphics drivers and sound drivers

The BSOD's seem to occur after a long period of my laptop in sleep, and usually in this case it is within minutes of waking, but it seems like every time I use it for an extended period of time, it will crash. I only added my two available dumps in the above folder, but many more than that have occurred. I think they were overwritten.

Also noted, Samsung does not offer the drivers or BIOS specifically for this device online, but only through the Samsung update app that comes pre-installed. I stay up to date on the updates, but I also try to manually update the drivers through device manager.

Any help would be much appreciated!

it would be very common for heat to cause this. Heat causes the card to use more power, more power used causes more heat. Bad cycle. blowing out dust from fans could help, extra case fans could help. setting the fans to max speed could help. overheated GPU memory can get glitches on screen. if windows detects the problem it might reset the card to get it to respond (minimum of a 2 second delay) The timing of electronic signals changes with heat also. The actual hardware can miss a electronic signal and mess up with overheating/overclocking.
the voltage drops when the card overheats and can cause improper voltage to the memory chips and cause graphic glitches

- I would make sure there was no GPU overclock driver installed, and the GPU fans are running at full speed.
(in case of heating problems, or GPU taking too much power)

- I would also take a look at the monitor's setting for sleep functions and turn them off (on the monitor side)

- I would look at the dates of all of the GPU drivers, Microsoft does updates and you can have mixed builds since Microsoft only updated one of the files. (or do a clean install via the GPU setup program)

- replace the HDMI cable with another good quality cable (shorter the better)

- check the BIOS some will have automatic overclocking of the PCI bus. it should be set to 100MHz
some try to set it to 103MHz to get extra performance but it can cause video problems.

-make sure your motherboard sound driver or any add on sound driver has been updated. If your CPU has a GPU built in then be sure to update the CPU sound driver. after everything is updated then you can go into control panel device manager and disable sound sources that do not have speakers connected to them.
sound devices do direct memory access thru a DMA controller that has 3 channels. if a driver gets data from the wrong device on a DMA channel it can overflow the drivers buffer and crash the driver. IE motherboard sound driver overflows the GPU sound drivers buffer and crashes the GPU driver or makes it stop responding.

you will also want to look at the monitor specs, high frequency monitors (144hz) require different cable specs (revision numbers)
Gsync and free sync monitors can also have bugs related to them. (not sure if there are updates to the monitor embedded software, but their might be special monitor drivers when windows knows what your monitor profile is)
google your monitor name + ICC monitor profile to see if there is a special version. laptops tend to have extra issues related to hardware design trade offs made so you might have to google for the issue + the laptop model name

In light of your response, this could be a heating issue rather than a HDMI or GPU issue. I use my TV as a monitor when playing video games on the laptop. Sometimes I play for a while and the fans work pretty hard. Could overheating be causing the black screens? I will check the BIOS and GPU fans as well.
