Hi @Adam,
Welcome to Microsoft Q&A forum.
Thank you for providing the details regarding the persistent black screen crashes and the LiveKernelEvent 141 and 117 errors you have been encountering. These errors indicate a Timeout Detection and Recovery (TDR) failure, where the Windows operating system loses communication with the GPU driver.
Given that you have already performed multiple clean Windows installations and driver wipes (DDU), we should focus on power delivery and system configuration. Kindly follow these steps to isolate the cause:
1. Power delivery method
Please ensure the GPU is not powered by a single "daisy-chained" PCIe cable. For a high-draw card like the 7800XT, you need to use two separate PCIe power cables directly from the PSU. This prevents voltage drops during transient power spikes that frequently trigger driver timeouts.
2. Disable Multi-Plane Overlay (MPO)
MPO is a Windows feature that can cause conflict with AMD drivers, leading to black screens. I recommend disabling MPO via the Windows Registry or using a reputable MPO Disable tool.
3. BIOS and Software configuration
- PCIe Link Speed: enter your Motherboard BIOS and manually set the PCIe slot speed to Gen 4 (or Gen 3 for testing) instead of "Auto."
- Software Conflicts: Completely uninstall MSI Afterburner and reset AMD Adrenalin to factory default settings. Overlapping overclocking utilities can cause low-level instability.
If the issues persist after these adjustments, we may need to consider a hardware-level assessment of the GPU or PSU. Please let me know the results after testing these changes.
I appreciate your cooperation and look forward to your update.
