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.
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?
