GeForce NOW desktop app causes crash and reboot (BugCheck 0x13A) after mouse/keyboard input

Hi everyone,
I’m experiencing a critical issue with the GeForce NOW desktop app on my main PC. Every time I launch a game and use the mouse or keyboard, the monitor shows “No Signal” and the entire PC reboots shortly after.
Oddly, controller input works fine, and the crash does not happen when using the browser version (Chrome) or when gaming locally.
The same GeForce NOW desktop app also works perfectly on my second PC (Minisforum UM760mini), using the same account and network connection.

Main system specs:​

• Windows 11 Pro (fully updated)
• AMD Ryzen 5 3600
• NVIDIA GeForce RTX 2060 Super
• LG 24GN650 (1080p, 144Hz, G-Sync Compatible)

What I’ve tried so far (no success):​

• Fully clean NVIDIA driver reinstalls via DDU
• Tested multiple older NVIDIA drivers (537.58, 531.79, etc.)
• Adjusted TDR registry values (TdrDelay, TdrDdiDelay)
• Reinstalled Media Feature Pack / reset Media Foundation
• Disabled G-Sync, HDR, fullscreen optimizations, hardware acceleration, and 144Hz
• Switched between DisplayPort and HDMI
• Tried older GFN app versions (2.0.36, 2.0.37 – no longer supported)
• Contacted NVIDIA support (no solution)

Additional recent steps:​

• Ran a full analysis of the crash Minidump →
  Result: BugCheck 0x13A (KERNEL_MODE_HEAP_CORRUPTION) caused by win32kbase.sys, triggered by mouse input event
  (specifically in HMAllocObjectEx inside the kernel input stack)
• Completely uninstalled Razer Synapse and all related drivers
• Switched to basic mouse and keyboard (no special drivers or software)
• Disabled Hyper-V via bcdedit /set hypervisorlaunchtype off
• Confirmed that Memory Integrity (VBS) was already off
• Performed a Clean Boot (only Microsoft services running)

I’m open to any ideas at this point.
Has anyone seen anything like this before — especially with an RTX 2060 Super or on Windows 11?

Thanks in advance for any help or suggestions.

Welcome to the forum. Sorry no one has responded sooner. For anyone to help you, you need to provide the necessary log files for analysis as instructed here. Then @zbook or one of the others experienced in analyzing logfiles can look at them.

I wanted to add that I’m having this issue too - to a T. Mouse/keyboard input causes a system reboot, but gamepad seems fine… really frustrating
