Question

How to fix Post-login black screen and UI hang, Desktop Window Manager (dwmcore.dll) crashes with 0xc00001ad after nvlddmkm TDR reset?

Summary of Issue

After I log into Windows, the system frequently gets stuck on a black screen. The PC remains powered on, but the desktop does not render, and the UI is unresponsive.

The only workaround is to keep moving the mouse cursor continuously for several seconds (sometimes a few minutes) until the desktop finally appears and Windows becomes usable.

Frequency: Always

Steps to Reproduce

Boot the PC.
Log into Windows.
The desktop loads for a second, then hangs, and the screen goes black.
Move the mouse continuously for several seconds/minutes.
Eventually the desktop appears, and the system works normally.
Sometimes it happen twice

Troubleshooting Already Performed

Clean NVIDIA driver installation using DDU or install manager with perform clean install check (currently: 610.62)
Install older NVIDIA driver 596.49
Ran DISM and sfc /scannow
Disabled hardware acceleration in applications
Connected GPU directly to the PSU (no adapter)
Set Windows power mode to High Performance also in NVIDIA settings
Reset MSI Afterburner (no overclock or undervolt)
Configured page file:
- Initial: 49,152 MB
- Maximum: 98,304 MB
Reinstalling Windows and logging in to a Microsoft account works for a while; I do not know what app is really causing it.

System Specifications

OS: Windows 11 Pro 25H2 Build 26200.8655

CPU: AMD Ryzen 5 8500G

GPU: NVIDIA GeForce RTX 5070 Ti 16 GB

Memory: 32 GB RAM

Dear Wadiska,

Thank you for reaching out.

From my initial review, current evidence suggests the black screen is most likely associated with graphics stack initialization during user logon. The strongest indicators are the AMD Radeon Software crash, followed immediately by multiple NVIDIA recovery events and DWM initialization errors.

At this point, the leading hypothesis is a conflict or instability involving the AMD integrated graphics environment and the NVIDIA RTX 5070 Ti display stack rather than a Windows shell or operating system corruption issue.

The recommended next step is to isolate the AMD graphics layer and validate the behavior under an NVIDIA-only configuration before pursuing deeper escalation.

Here below I attach the Technical Analysis Summary, kindly let me know if further clarification is needed. Thank you.

Issue Description

Users experience a recurring black screen immediately after signing into Windows 11. The system remains powered on and responsive to mouse movement; however, the desktop does not render properly and the user interface becomes unavailable. Continuously moving the mouse for an extended period eventually allows the desktop to appear and the system to function normally.

The issue reproduces consistently and may occur multiple times in the same session.

A clean Windows installation temporarily mitigates the issue before it eventually reoccurs.

Event Log Findings

1. AMD Radeon Software Component Crash - Event ID 1000 (Application Error)

This indicates a crash involving AMD Radeon Software components during user logon.

Notably, the affected system uses a Ryzen 5 8500G processor, which contains an integrated Radeon GPU in addition to the installed NVIDIA RTX 5070 Ti.

Observation: The timing suggests AMD display-related components are actively involved during system initialization and may be interacting with the graphics stack during the failure period.

2. NVIDIA Driver Recovery Events

Multiple NVIDIA driver events were recorded immediately after the black screen occurrence:

Event ID 153 – nvlddmkm

Several instances were observed within seconds of one another.

Event ID 14 – nvlddmkm

This indicates the NVIDIA driver detected an error condition and initiated a GPU recovery procedure.

Observation:These events occur during the exact timeframe when the customer experiences the black screen.

3. Desktop Window Manager (DWM) Involvement

A DwmInit event was also recorded referencing:

The Desktop Window Manager (DWM) is responsible for graphical desktop composition and rendering.

Observation:The coexistence of DWM events and NVIDIA recovery events suggests the graphical desktop rendering pipeline was interrupted or delayed during logon.

4. Secondary Application Hang

Event ID 1002 (Application Hang) was captured for:

This appears to be a downstream symptom occurring after the display stack instability rather than the primary root cause.

Technical Assessment

Based on currently available evidence, the issue appears more related to display stack initialization and GPU recovery than to typical shell startup or Explorer.exe failures.

The following sequence is observed:

User completes Windows logon.
AMD display-related component crashes.
NVIDIA driver records multiple recovery/error events.
DWM experiences initialization issues.
Desktop rendering is delayed or unavailable.
Eventually, the graphics stack recovers and the desktop appears.

The event correlation significantly strengthens the hypothesis of a graphics subsystem issue rather than:

User profile corruption
Explorer.exe crashes
Page file configuration
Windows file corruption
Startup application delays

At this stage, the most probable causes are:

Primary Suspect

Interaction between AMD integrated graphics components and NVIDIA RTX 5070 Ti display stack

Evidence:

AMD Radeon Software crash
Ryzen 8500G contains integrated Radeon graphics
NVIDIA recovery events immediately follow
DWM instability observed

Secondary Suspect

NVIDIA display driver / desktop composition instability

Evidence:

Multiple nvlddmkm Event 153 errors
Event 14 GPU recovery action
DWM involvement

Less Likely

Hardware GPU defect
PSU insufficiency
Windows corruption
Explorer shell failures

Current evidence does not strongly support these scenarios.

Recommended Next Actions (please ensure a backup is available once needed)

1. Eliminate AMD Graphics Stack from Testing

Uninstall AMD Radeon Software (retain chipset drivers only)
Disable AMD integrated graphics in BIOS if not required
Configure system for NVIDIA-only operation

2. Verify Display Adapter Configuration

Confirm whether Device Manager currently shows:

1-AMD Radeon Graphics

2-NVIDIA GeForce RTX 5070 Ti

If both are present, test with AMD adapter disabled.

3. Test Multiple Reboots

Perform repeated logon cycles after AMD component removal to determine whether the issue reproduces.

4. Collect Additional Data if Repro Persists

Reliability Monitor logs
GPUView / ETW traces
NVIDIA driver diagnostic logs
ProcDump capture during black screen event

Hi Xuan Nhu,

Thank you for taking the time to help me troubleshoot this issue.

I went through your suggestions one by one and tested each change individually. After several rounds of testing and multiple restarts, I was finally able to narrow down the root cause.

From what I've observed, the main issue appears to be related to the NVIDIA App, not the NVIDIA graphics driver itself. I'm still not sure which component of the NVIDIA App is causing the conflict, but based on some reports I found, it may be related to the in-game overlay or one of its background services.

For comparison, I also tested with the AMD software installed, along with MSI Afterburner, and I haven't experienced the same problem. Everything has been stable so far, although I plan to continue testing for a few more days to make sure the issue is completely resolved.

At the moment, I have uninstalled the NVIDIA App and am using only the NVIDIA Control Panel. Since doing that, the post-login black screen and UI hang have not reappeared.

Below are the restart results I've collected so far:

At this point, the only remaining issue I can see is related to the Host Network Service. It doesn't appear to be critical and isn't affecting normal system usage, so I'm treating it as a separate issue for now.

However, if you have any ideas or would also like to help me investigate the Host Network Service issue, I would really appreciate it.

Hopefully this information is useful for your investigation, and it may also help others who encounter the same issue.

Thank you again for your support!

Hi Wadiska,

Thanks so much for sharing your test results.

Based on your confirmation, it looks like the NVIDIA App is causing the black screen - UI hang issue. At this point, it would be a good idea to check with the NVIDIA support community to see if this is a known issue and get their recommendations.

As for the Host Network Service error reported by the VSS component, it doesn’t seem related to what we’re experiencing right now, so you can safely ignore it for the current flow.

Let me know if you need any further help! Thanks for your effort in troubleshooting and documenting.
