I had to RMA my CPU and replaced it with the exact same model. After the replacement, Windows no longer recognized it as genuine and lost its activation/license. I’m not sure if this is related to the problem, but it was another change compared to the period when everything was working fine.

I’ve already tried setting a higher priority for the audiodg.exe process and limiting it to CPU core 0 only. All my inputs and outputs are set to the same sample rate (48 kHz).

What else can I try to fix this? I have to use the “Restart Audio Engine” option every five minutes or so to temporarily stop the audio from crackling.

The Problem:

My PC randomly reboots (black screen, no BSOD) when dragging a video from the project panel to the timeline in Adobe Premiere Pro. This is 100% reproducible. Windows Event Viewer shows Cache Hierarchy Error (WHEA-Logger Event 18) on different CPU cores.

The History:

It started with my original Ryzen 5 3600. AMD RMA'd it and gave me a refund. I bought a Ryzen 7 5800X3D with the refund. The problem persisted.

At one point, replacing the PSU fixed it for a few months. Then it came back. Removing an undervolt stabilized it for about a month. Then it came back.

Updated BIOS to the latest version. No change. Disabled DOCP/XMP. No change.

Updated GPU drivers, removed GPU undervolt, disabled hardware acceleration in Premiere. No change.

What I've Already Replaced (yes, everything):

• CPU: Ryzen 5 3600 → Ryzen 7 5800X3D
• Motherboard: Multiple models tested (currently Asus TUF Gaming B550M-Plus)
• RAM: Multiple kits tested (currently Corsair Vengeance LPX 32GB 3600MHz)
• GPU: Multiple models tested (currently RX 5700 XT)
• PSU: Multiple units tested (currently XPG Core Reactor II 850W Gold)
• SSD/Storage: Multiple drives tested (currently Adata Legend 860)
• Monitor: Changed
• Keyboard/Mouse: Changed
• Router/Network: Changed
• Eletric: Changed (even moved to a different house during this process)

What I've Tried Recently:

• Disabled DOCP (RAM at stock 2133MHz)
• Removed all undervolts (CPU and GPU)
• Updated BIOS to latest
• Clean GPU driver install with DDU
• Disabled hardware acceleration in Premiere

System Specs:

• CPU: Ryzen 7 5800X3D
• GPU: RX 5700 XT
• Mobo: Asus TUF Gaming B550M-Plus
• RAM: Corsair Vengeance LPX 32GB (2x16) 3600MHz CL18
• PSU: XPG Core Reactor II 850W Gold
• Storage: Adata Legend 860 1TB NVMe

Additional Context:

• The error is 100% reproducible in Premiere Pro (drag video to timeline = instant reboot)
• Gaming (DayZ, SCUM) and other workloads (Photoshop, Illustrator) are usually stable
• Event Viewer shows Cache Hierarchy Error (Event 18) with different APIC IDs
• No BSOD, just instant black screen and reboot

Has anyone ever seen anything like this? I'm at my wit's end after 7 years. Any suggestion, no matter how crazy, is welcome. I'll try literally anything at this point.
