Question nvlddmkm.sys Win 10 Blue Screen of Death - 2070 Super

[PC Gaming 013]

Hey all,

I’ve a Nvidia 2070 Super, and a couple of weeks ago I started regularly getting the Video TDR Failure nvlddmkm.sys blue screen. When it first occurred, nothing out of the ordinary was going on, just gaming like normal, when it just crashed and the BSOD came up. Since then, it’s been happening regularly when gaming, but it’s fine when just at idle – I can leave my PC on all night and nothing happens. Below are more details, let me know if there's anything else I can try to resolve the issue, or if it's looking like a hardware failure.

I built my PC in fall of 2019, so it’s three years old – one month past the 2070’s warranty. :/
---PC Specs – nothing is overclocked---
MOBO: Gigabyte Z390 Designate LGA 1151 (300 series)
CPU: Intel i7-9700K
Graphics: Nvidia 2070 Super ("founders" edition)
RAM: Corsair Vengeance Pro DDR4 3200 – 64 GB
SSD: Samsung 970 EVO Plus – 500 GB
OS: Win 10 Pro
PSU: Corsair AX850 PSU
Monitor: Dell S2417DG
UPS: CyberPower CP1500PFCLCD

I googled the issue, and tried many of the proposed solutions, such as the following:
-Updated motherboard BIOS
-Removed old Nvidia drivers using DDU
-Tried both old and up-to-date drivers
-Updated Windows
-Removed 2070 super from the PC and blew all the dust out with pressurized air
-Ran CKHDSK & SFC
-Ran Window’s Memory Diagnostic a few times – no errors
-And several other minor things I can’t remember

I’ve run OCCT with mixed results. Sometimes I’ve let it run for 30 min with no issues. Other times it’ll freeze after just a few minutes with artifacts on the image (see pics below).

I'm happy to post event logs, though I don't know my way around them very well, so please be specific in what you're looking for.

Video TDR Failure

TDR stands for Time-out, Detection and Recovery. It's a module in Windows that monitors Video drivers. In this case, your video driver (nvlddmkm.sys) stopped responding to the system's requests for long enough or was irregular enough that the TDR module detected the driver was malfunctioning. nvlddmkm.sys is the core file of the Nvidia Display Driver that interfaces with your system's core parts (kernel, hardware, etcetera).

Could you install Nvidia Inspector (Guru3D), run a small benchmark on your computer, and post the results from that window? This would be handy for checking the default statistics of the card and how it's behaving regarding boost clocks.

Additionally, did you change anything about the rig like other hardware?

Sure, see link below. I ran OCCT for 5 min then grabbed a screenshot of Inspector.

I hadn’t made any changes to the rig before this started happening.

Let me know if there’s anything else.
