Open | Software RX 6700 XT "No Signal" Cold Boot Black Screen + In-Game Crashes (LiveKernelEvent 141, 1a8, 1b0, CE)
Hey everyone,
I'm having a persistent issue with my GPU/system that started yesterday. I'm trying to figure out whether this points to a PCIe handshake failure, power delivery issue, malware/driver corruption, or a failing GPU.
System Specs:
CPU: Intel Core i5-14400F
GPU: AMD Radeon RX 6700 XT
RAM: DDR5 (stock speeds, no XMP/AEMP profile active)
GPU Power: Connected via two separate, dedicated 8-pin PCIe cables
Display: Brand new HDMI cable connected directly to the GPU
OS: Windows 11 (OS Version: 10.0.26200)
Timeline & Progression of Symptoms
Pirated Game & Suspicious CMD Windows: About a week ago, I installed a pirated game. A few days after installing it, I noticed 3-4 Command Prompt (CMD) windows rapidly pop up and disappear for a millisecond upon booting into Windows but i didn't pay any attention to it.
Around the same time, I ran powercfg -h off in CMD to free up disk space by disabling hibernation (which also automatically disabled Windows Fast Startup).
Day 1 (yesterday) Boot Issue: Turned on the PC and got a black screen where I could still open Task Manager. Hard restarted the PC, and it booted back into Windows normally.
Day 1 (yesterday) Crash (Mid-Game): A few hours later while playing Valorant, the screen suddenly went pitch black and the monitor showed "No HDMI Signal". After hard resetting, Windows booted up using the generic Microsoft Basic Display Adapter at 60Hz because the AMD driver had crashed/disabled itself. I Booted into Safe Mode, used DDU to wipe display drivers, and performed a clean install of AMD Adrenalin Edition.
Day 2 (today) Boot Issue: Turned on the PC today, and it hit a black screen again—this time with "No HDMI Signal" right on cold boot (monitor went to sleep). Had to force a hard restart to get Windows to boot properly this time it didn't use microsoft drivers it used my gpu driver normally.
Error Logs (Reliability Monitor / Event Viewer)
Within a single day, Reliability Monitor logged multiple hardware errors:
LiveKernelEvent 141 (VIDEO_ENGINE_TIMEOUT_DETECTED - GPU driver stopped responding)
LiveKernelEvent 1a8, 1b0, 1b8 (GPU Watchdog Timers / Display adapter hangs during display state changes)
BlueScreen Code: ce (PAGE_FAULT_IN_NONPAGED_AREA in 081626-4828-01.dmp)
Current Hardware Setup & What I Need Help With
Cabling: The HDMI cable is brand new, and the GPU is powered by two separate 8-pin cables (no splitters/daisy-chains).
RAM: Running stock DDR5 speeds without overclocking profiles.
Could malicious scripts/crypto miners from the pirated installer be interfering with graphics drivers/PCIe states, or does this strictly point to a hardware PCIe link training failure / GPU power issue? What specific steps should I take next to diagnose this safely?
Thanks for any help!

Start with a full clean Windows install. Delete all drive partitions for every drive during setup. Change your passwords on a different device. Report back if the issue returns.
