Dealing with driver crashes on ASRock Z370M Pro4 with RTX
Every time I stepped into a complex RTX shader area, the game would just vanish to the desktop without warning. The anxiety of not knowing when the next crash would hit was real. The PCIe link on the ASRock Z370M Pro4 was struggling with the high-bandwidth ray tracing data, causing a 0.5-0.8ms delay during power state transitions, which made the GPU driver stop responding. I wasted so much time clearing shader caches, but the crash frequency didn't budge—it was a total nightmare. I finally went into Device Manager and killed the 'PCI Express Link State Power Management' and flashed the latest BIOS. The disk timeout errors in Event Viewer completely stopped, and I managed five hours of gameplay without a single crash. One annoying side effect: the BIOS update slowed my boot time by about 10 seconds until I disabled Fast Boot. Motherboard temps are 55-61℃ and CPU is 68-74℃. 3DMark storage tests confirm the I/O link is finally stable, and the input lag is gone.
