Have you encountered difficulties with a hard reboot on your new PC setup?
Have you encountered difficulties with a hard reboot on your new PC setup?
Hi everyone,
I recently assembled a new PC and have encountered several crashes and stability problems. Here are the details:
- CPU: AMD Ryzen 9600X
- CPU Cooler: Thermalright phantom spirit
- GPU: PNY RTX 4070 TI Super
- PSU: Corsair RM1000x (2021)
- RAM: Corsair vengeance 6000mhz CL30 32 (2x16) GB
- SSD: Kingston KC3000 2TB
Summary of findings:
Initial stability checks were successful, but game crashes prompted a re-evaluation. It’s still unclear which part is responsible.
Testing steps I’ve tried:
- Double-checked all power connections
- Reinstalled drivers using the DDU method (latest versions)
- Ran tests with and without EXPO enabled
- Switched to an older, functioning GPU and tested with the integrated graphics
- Performed stress tests: OCCT suite, FurMark, MemTest86/86+, TestMem5 (Extreme1 @ anta777), Prime95, etc.
- Tested RAM sticks separately
- Monitored voltages and temperatures during crashes (all within normal limits)
Quick timeline:
- The PC passed initial stress tests (OCCT suite, FurMark) and remained stable for about 10 minutes of light gaming.
- Stable for a week without intensive use.
- Crashes started in games (RoR2 after 2–5 minutes; Hades after ~15 minutes), requiring hard restarts.
- Stability checks (OCCT CPU+RAM, Prime95) began failing after 2–5 minutes, even with the integrated GPU.
- Further tests showed mixed results, with occasional stability during longer sessions.
Challenges:
- Limited access to spare parts beyond the GPU for deeper diagnostics.
- Documentation of findings is available here: [link]
- Hard reboots were less frequent in recent tests but were the main cause of crashes.
Quick thoughts:
- PSU: Reliable and new; crashes occurred across GPUs and even on integrated graphics, sometimes handling high power, other times lower.
- RAM: Consistently passed all specific tests (Memtest86/86+, TestMem5 Extreme1) without errors.
- Survived 8 hours of Prime95 at some point.
- Prime95 showed inconsistent behavior—early crashes in some runs but survival in others.
CPU:
- Passed extended Prime95 and OCCT CPU Extreme in certain tests.
- Likely a secondary suspect for other Prime95 failures if RAM is the culprit.
- MOBO: Could play a role in instability with RAM or CPU.
General system:
- Passed extended OCCT Combined and Prime95 runs during some sessions.
- Stable when not gaming or performing tests.
Additional notes:
- Main crash pattern: Hard reboot (screen goes black, sound for 1–2 seconds, then system restarts).
- Event Viewer logs often point to other drivers (NVIDIA, Realtek) but frequently display volmgr and Kernel-Power errors.
- Occasionally the GPU wouldn’t load into Windows at all, only into BIOS, sometimes not showing up at all for a short time. Reseating the GPU, cables, and RAM helped resolve the issue.
Any assistance would be greatly appreciated. I’m happy to share more updates as they come in. Thanks!
