PC Freeze nvidia graphic card


My spec:
i7 6700hq
8gb ddr4
Intel HD 530 - GTX 950M 4GB
256GB M2 SSD

Windows 10 version 1803

I have problem with my grpahic card driver Nvidia GTX 950M 4gb after updating my windows.
After install or during the installation last verison (or previous) of driver, my computer go to freeze or blue screen.
I try all way to install older version windows, older version driver, but there is the same situation.

Troubleshooting: I've installed a new OS several times and EVERYTIME I install my nVIDIA drivers, my laptop either blue screens with the error code "DPC_WATCHDOG_VIOLATION" or "NVIDIA VIDEO SCHELUDER INTERNAL" just simply freezes till i have to hard reset it. I've also ran diagnostic tests to make sure it is not a hardware problem. Lastly, I've ran DDU and uninstalled my GPU and tried installing the drivers both from nVIDIA and from my laptops manufacture site and the issue just arises again.

Can you help me?

Thank you!

You won't guess what it was for me.

This happened to my Lenovo with dual 750 GPUs. It took a while to figure it out but today I can find it much faster. Let's see a Web Speccy report (link on how to follow) and we'll be check the HDD health. If you find the drive with out of this world numbers in 01 and 07 you may have found a cause.

There are others you can google about but here, I'd look for that. And yes, your new tech doesn't get the interaction or why the HDD health matters.

Good to see.

In reply to: replay

There is another issue there. Single channel RAM but let me look over the Speccy and while I do that get your test up here too.

Remember I take it you already googled DPC_WATCHDOG_VIOLATION" or "NVIDIA VIDEO SCHELUDER INTERNAL" so I won't try to note what has been covered and tackle this the other way.

Be right back with a longer Speccy reading.

A Speccy reading.

1. Single channel RAM. I'd fix that.
2. The 950M did not show up in the Speccy so my new bet is the OS is installed but the usual post OS work hasn't been done. REMEMBER that Windows and driver updaters rarely get this right. So back to Lenovo and update the BIOS, then install the motherboard chipset drivers, then AUDIO and see where you stand. Windows might install the 950M driver, it might not. I'd avoid that and just install the Nvidia GeForce Experience at this step to see how it does on the drivers.

3. BIOS update is noted as CRITICAL at
I'd get that done BEFORE any more driver work. It may also help the RAM UNKNOWN item. We'll see.

4. Disable this for speed, etc.

Thank you for the previous answer that helped me install the Nvidia driver after updating the BIOS. The laptop is now OK unless I hit the task manager to stop and wait for 30 seconds when the screen blinks sometimes knock out NVIDIA VIDEO SCHELUDER INTERNAL

I have installed all Lenovo drivers and so on.
Ram still has an unknown unknown about what?

Here are speccy new so if you could look.

Thanks in advance

I'll be back.

In reply to: thanks

In a few with a new Speccy reading.

That error has plenty of priors so in short it's either a driver or hardware issue. SMALL COINKIDINK is:

There's another Lenovo there so try their ideas on a VESA version or other version driver.

What is and how to use canned air is on YouTube so I just note it and move on.

At least it sounds like some progress.

A Speccy reading for Jan 29 2019. More BADWARE!

In reply to: PC Freeze nvidia graphic card

1. I don't like the (Unknown) for RAM and SSD. This is sometimes cosmetic and sometimes not.
For the SSD, use the Samsung page for your SSD and see if Samsung has new firmware.
If not try since it will scan for such for you.

2. More badware.
It's those scheduled "online application" items.
Try Grif's scans again at

If they don't clear it up, head to , sign up and follow their rules about posting to get going.

Wow that sounds nasty. It's either a TDDS or which steals information. I defer to Bleepingcomputer on this one like:

3. Be sure this is disabled:

Prior notes about dual channel RAM still apply.

I followed from your previous answer and I deleted viruses. However, the task manager is sometimes frozen, so the windows sometimes blink the black screen and unfreeze, but I can not run the game on gtx 950m because it releases erorr.

Re: errors

In reply to: Erorr

Although in your first post you say that you are sure it's not a hardware problem, I'd try another videocard (use DDU to delete all drivers for the old one) to be sure it's not the hardware of the videocard.

In reply to: Re: errors

I tried all the other drivers but still have a problem.

10 days ago I played a hitman 2016 game and everything worked fine, but Windows update has done so since then I came across this erorr, I tried all the drivers and I came back to the previous versions but failed.

Re: drivers

In reply to: drivers

You can undo a Windows 10 update from the settings app. Or by going back to your latest image. Or by restoring from the recovery drive you made (this is not optional if you don't make image backups). Or by going back to factory conditions. Or by reinstalling Windows 10 yourself from the original .iso-file you downloaded.

And you can install old and new versions of drivers.

But you can't undo hardware failures. For those, you need new hardware.

While hardware is still suspect.

In reply to: Erorr

Try the following:

This is also known to be the video driver as well as failing hardware. Since there are multiple causes you try the drivers and when you hit the end it's hardware.

In some cases we can extend the lifespan of the gear by disabling something. For example if this only happens on YouTube in a browser we google with this to disable...: Chrome Disable Hardware Acceleration.

The mess here is we found badware which muddies the picture.

This is done, but still the problem freezes the opportunity to enter a task manager or launch a nvidia graphics card. Sad

The water is muddy. (The badware)

In reply to: :(

Since there is some doubt about the OS and the infections try since they have other scans and tools.

Frankly if this laptop works with the Intel and a factory load doesn't clear it up then it's just another 950M failure. Nod to

It's just something you see from time to time and repair costs as much as a laptop. Just use it as a laptop with the Intel graphics and it usually works for a few more years.
