BSOD when playing games, VIDEO_SCHEDULER_INTERNAL_ERROR 0x119

I think it's about the Nvidia graphic card driver. BSODs started a couple weeks ago whenever I tried to start a game, most of the issues were dpc_watchdog_violation and system_thread_exception_not_handled. Then I uninstalled the previous video card driver (which was the newest) and installed the older version 361.75. It worked but not perfectly, sometimes it just turned into blackscreen and froze (uninstalling the driver by using DDU then reinstall it could solve this issue, but it just reappeared after rebooting).

Today another BSOD just appeared again when I was playing a game, and this time it showed video_scheduler_internal_error 0x119 in orange screen.

I wish I could upload my previous minidumps, but I just got my Window 10 anniversary update done so all of them were gone.

Update: BSODs happened twice today. The first one was dpc_watchdog_violation (according to WhoCrashed) had it happened when I did nothing. The second one was triggered when I was running DM Log collector. Attachment 151651_54 was the updated version.
Attachment 94220

Update (Aug 27 2016): Just updated the newest Nvidia driver version 372.54 after Windows 10 anniversary update. Problem seems to be solved.

Look in C:\Windows.old\Windows\minidump, see if they are there.

Only 1 dump. It does show that your PC is slightly under clocked:

Code:

0: kd> !sysinfp cpuspeed
No export sysinfp found
0: kd> !sysinfo cpuspeed
CPUID:        "Intel(R) Core(TM) i7-4712HQ CPU @ 2.30GHz"
MaxSpeed:     2300
CurrentSpeed: 2295

I suggest entering BIOS Setup and setting values to default then run for awhile. If you get any more BSODs please re-run DM_Log_collector and upload the zip file.

Dump, as you stated, points at watchdog.sys which is a Microsoft file and part of the OS. Highly unlikely to be the actual cause. More likely a driver or memory problem of some kind. Lets see if we can find out more.

===================================================
Driver Verifier is a diagnostic tool built into Windows 10, it is designed to verify both native Microsoft drivers and third party drivers. Driver Verifier's verification process involves putting heavy stress on drivers with the intention of making bad, outdated, incompatible or misbehaving drivers fail. The required result is a BSOD (Blue Screen of Death) which will generate a crash dump for debugging purposes.
Machines exposed to Driver Verifier will run very sluggishly due to the stress being applied to the drivers.

Pay close attention to
PART TWO
and make sure the correct boxes are checked.

Warning:
It is not advised to run Driver Verifier for more than 48 hours at a time. Disable Driver Verifier after 48 hours or after receiving a BSOD, whichever happens soonest.

Always create a Restore Point prior to enabling Driver Verifier.

What we're looking for is a BSOD with a mini dump that will tell us what driver caused it.

Also, I can't find anything on the internet about the HP ENVY 15 9004TX laptop. Do you have a link to the page where it's manuals and device drivers can be found?

The dxdiag report indicates you have a onboard Intel(R) HD Graphics 4600 and a discreet NVIDIA GeForce GTX 850M.

The dump shows a problem with the Nvidia driver:

Code:

fffff801`50078220  fffff809`25ca95ecUnable to load image nvlddmkm.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for nvlddmkm.sys
*** ERROR: Module load completed but symbols could not be loaded for nvlddmkm.sys
 nvlddmkm+0x9695ec

Did you try the Nvidia 368.81 version driver? Is that what you had before? If not, uninstall using DDU then try the 368.81 version, or try the one on the HP web site, the 353.24 version. There are a lot of driver versions between 353,24 and 368.81. Try some of them, see if better?

What about running with the onboard Intel video? I don't know how that performs for gaming, probably not well though.
How long have you had the laptop? If it's still in warranty contact HP and get them to fix it or replace it.

Still the Nvidia card.

Code:

BugCheck D1, {0, 2, 8, 0}
*** WARNING: Unable to verify timestamp for nvlddmkm.sys
*** ERROR: Module load completed but symbols could not be loaded for nvlddmkm.sys
Probably caused by : nvlddmkm.sys ( nvlddmkm+10b534 )

All I can suggest is to try other driver versions until you find one that works. Also make sure nothing is overclocked (if that is even possible with the Envy 15 laptop).

Other than that I don't know what else you can do. I don't believe the Nvidia card is replaceable. If it was I'd suggest doing so.

Could try running memory diagnostics on the chance that it is the actual root cause. Noting points to it but what if? It's something that can be replaced.

RAM:

Follow this tutorial: MemTest86+ - Test RAM - Windows 10 Forums

Information


MemTest86+ is a diagnostic tool designed to test Random Access Memory (RAM) for faults. MemTest86+ will verify that:

• RAM will accept and keep random patterns of data sent to it
• There are no errors when different parts of memory try to interact
• There are no conflicts between memory addresses

Memtest86+ runs from bootable media to isolate the RAM from the system, no other components are taken into account during the test.

Warning
MemTest86+ needs to run for at least 8 passes to be anywhere near conclusive, anything less will not give a complete analysis of the RAM.

If you are asked to run MemTest86+ by a Ten Forums member make sure you run the full 8 passes for conclusive results. If you run less than 8 passes you will be asked to run it again.

Note
MemTest86+ has been known to discover errors in RAM in later passes than the eighth pass. This is for information only; if you feel there is a definite problem with the RAM and 8 passes have shown no errors feel free to continue for longer.

Running 8 passes of MemTest86+ is a long and drawn out exercise and the more RAM you have the longer it will take. It's recommended to run MemTest86+ just before you go to bed and leave it overnight.
