Hello everyone, I’m facing ongoing system stutters across idle and app launches—not limited to gaming. LatencyMon indicates frequent DPC latency peaks, mainly linked to nvlddmkm.sys (NVIDIA driver) and dxgkrnl.sys. My specs: AMD Ryzen 7 7700, NVIDIA GeForce RTX 5060, 32GB RAM at 5600 MT/s, Gigabyte B850 motherboard, WIFI6E BIOS (latest), running Windows 11 Build 26100.

What I’ve tried: Enabled Ultimate Performance power plan, cleaned install of NVIDIA drivers (GPU, HDAudio, PhysX), disabled registry tweaks and telemetry. Some BIOS adjustments helped. LatencyMon shows the highest DPC execution around 2900 µs in nvlddmkm.sys, with spikes from dxgkrnl.sys and occasional page faults from msmpeng.exe.

I need advice—are there specific BIOS or Windows tweaks for Ryzen + NVIDIA setups that could lower this latency? Any step-by-step method to pinpoint the issue without a full reinstall would be great. Thanks for any guidance!

nvlddmkm.sys is a genuine Nvidia component and usually indicates a hardware failure. However, it could also stem from a software problem. First, check if you have a backup power supply to test your system. If the GPU isn’t getting enough power, that might cause the issue. The 5060 model isn’t very power-hungry, but a faulty PSU can still lead to problems. Nvidia drivers have had many issues since the 5000 series was released. You might try installing an older driver in case it was more reliable. What brand is your GPU? If it’s from Asus, visit their site and download the latest Nvidia driver—they’ve made updates for better stability. Finally, Windows 11 has caused some frustrations; trying Windows 10 could help resolve certain problems. Good luck!

Thanks for your response! Since I don’t have a backup PSU available, my unit is new and has handled load without issues—no crashes or shutdowns. I’ll keep power delivery in mind. My GPU is a Gigabyte RTX 5060, so I’ll check their support site for drivers and look for a customized or stable version versus NVIDIA’s latest. I’ve already reinstalled several drivers using DDU, but not the ones made by Gigabyte specifically. On Windows, I’m using version 11 (Build 26100). Some users suggest reverting to Windows 10 for improved stability with NVIDIA drivers, which could be worth trying if needed. Thanks!
