Question Been trying to fix for 7 days! Persistent different DPC Watchdog Crashes RTX 4090/MSI 321URX OLED

[Moonhawkmanton]

I recently got the new MSI OLED Monitor. Plugged in and ran Cyberpunk 2077 ran it in background while watching a video on setting up HDR, started using the Monitor settings on the actual monitor and got a blackscreen freeze and audio freeze crash. When it rebooted, it had to go into recovery. It repaired itself enough to start up but I noticed that it thought Cyberpunk, Icloud, and a few other programs were no longer on the c: drive. Since then I have been getting persistent DPC Watchdog crashes during gameplay only, internet and video playback is fine. Please help I am getting OCD'd out right now and have lost about a week of free time trying to correct this.

I have restore windows and updated fully from 10 to 11

System Configuration​

• Operating System: Windows 10 (first) now 11
• GPU: Zotac RTX 4090
• CPU: Intel i9-9900K
• PSU: Corsair RM1000x
• Cooling: Air cooling with case fans and GPU/CPU fans
• Monitor: Two monitors tested, including an AOC U34G2G4R3 and a new MSI 321URX QD-OLED

---

Issues Experienced​

• System Crashes: Occurred during gameplay across multiple games, including Cyberpunk 2077, Green Hell, and Hogwarts Legacy.
• Inconsistency: Crashes often happen before the 1-hour mark but not always, making it difficult to pinpoint the exact cause.

Steps Taken​

1. GPU Testing​

• FurMark Stress Test:
  • Ran FurMark (GL) and FurMark Knot (GL) for over an hour with no issues. GPU was stable, with temperatures peaking at 73.8°C.
  • GPU memory clock consistently at 2625 MHz during gameplay, and VRAM usage peaked at 7753 MB.

2. CPU & PSU Testing​

• OCCT Power Supply Test:
  • Ran the test for 1 hour with CPU max MHz at 4551.9 and 100% utilization. No errors detected.

3. Memory Testing​

• MemTest86:
  • Ran MemTest86 with no errors detected.

4. Driver Reinstallation​

• NVIDIA GPU Drivers:
  • Used DDU (Display Driver Uninstaller) to uninstall GPU drivers and performed a clean installation of the latest NVIDIA drivers.
• Windows Event Viewer Logs:
  • Analyzed Event Viewer logs, with critical errors such as Event ID 41 (Kernel-Power), Event ID 1001 (BugCheck), and others pointing to potential hardware or driver issues.

5. Crash Analysis​

• BlueScreenView & WhoCrashed:
  • Analyzed crash dumps, with results pointing to ntoskrnl.exe, which typically indicates underlying driver or hardware issues.
  • BugCheck code 0x00000133 identified as DPC_WATCHDOG_VIOLATION, often related to driver or hardware issues.

6. General Troubleshooting​

• HWiNFO Monitoring:
  • Monitored GPU, CPU, and other system metrics during gameplay and stress tests, looking for anomalies leading up to crashes.
• Tested on Different Monitors:
  • Tested with both the new HDR monitor and the older AOC monitor, with crashes occurring on both.
• Checked BIOS & Firmware:
  • Verified that BIOS and firmware were up to date.
• Checked Windows Updates:
  • Ensured that Windows 10 was fully updated.

i would try a different cable. then i would try different ports on the gpu and then monitor. are you using those monitors in a dual setup? maybe just try one at a time til you get sorted. also that new monitor had two firmware updates since june with a heap of fixes have you applied them? if the psu is from the original 9900k build it may be getting a bit old now - possibly on the way out - i'd try and test out another one after you exhaust your easier options.
