I've been getting frequent KERNEL_SECURITY_CHECK_FAILURE (0x139) blue screens over the past few weeks, usually while working in FL Studio with a Focusrite audio interface. I previously had several audio-related drivers installed, including Waves SoundGrid, Sonarworks Reference, VB-Cable, and Voicemeeter, but I have since removed them after hearing they can cause instability. The minidump files are available for analysis. I also experienced one complete system freeze while gaming, requiring a forced shutdown; the mouse still moved, but Windows otherwise stopped responding. The affected games include Wuthering Waves, Palworld, Cyberpunk 2077, and Diablo 4. My system has a Ryzen 9 5900X, Corsair Vengeance Pro SL CL16 memory, an RTX 4080 Super, an ASUS B550-F Gaming motherboard, a 1200W Thermaltake PSU, and an NZXT Kraken Elite 360 RGB cooler. What should I check to identify whether the problem is faulty memory, an unstable memory profile, or a driver issue?

A likely first test is to disable the memory overclock. With two DIMMs, the Ryzen 9 5900X officially supports DDR4-3200, while your DDR4-3600 kit is running above that specification. Even if the system usually works, that extra speed can cause intermittent 0x139 crashes and gaming freezes. In the BIOS, choose Auto rather than the D.O.C.P. profile, or manually set the memory to 3200 MT/s, then test the system for a while. If the crashes stop, the memory profile was probably unstable.
The minidumps are the right place to investigate a blue screen because they record the crash context and possibly the driver involved. However, a 0x139 does not automatically prove that an audio driver is responsible; corrupted memory or unstable RAM settings can also damage kernel data and trigger it. Since the memory was recently replaced, test it at stock settings with a memory diagnostic tool and run Windows system-file checks. If crashes continue, enable small memory dumps and review several of them together rather than relying on a single crash. Avoid reinstalling Windows as the first step, and back up important work before doing hardware or driver troubleshooting.
I didn’t realize 3600 was technically over the CPU’s official rating. My BIOS offers Auto, Manual, and D.O.C.P.; I’ll try Auto first to return the memory to its default speed.
