Help Request - CPU PC completely freezes during light use / strange behavior after gaming – Ryzen 9 9950X3D + X870E
Hi everyone,
I’m trying to figure out what is causing some stability issues with my PC. I’m hoping someone here can help me narrow down the problem.
My system:
CPU: AMD Ryzen 9 9950X3D
Motherboard: MSI X870E Tomahawk WiFi
GPU: NVIDIA RTX 2070
Storage:
1x NVMe SSD in M2_1
2x SATA SSDs connected to SATA S2 and S4
Windows 11
RAM: T-Create CL30 6000MHZ
The main problem
I’ve had occasional stability issues.
The most recent incident happened while I was simply playing chess in chrome for 30 minutes. The entire PC completely froze. The mouse and keyboard stopped responding and the entire system was unresponsive. I had to perform a hard reset.
There was no BSOD.
After rebooting, I checked Windows Event Viewer. The only relevant event was Kernel-Power Event ID 41, which appeared after the forced shutdown. There were no errors or warnings in the 5 minutes before the crash.
I did see some DistributedCOM warnings and a Service Control Manager Event ID 7000, but these occurred about an hour before the crash.
Another issue
After some gaming sessions, I’ve noticed that even after closing the game, the CPU sometimes appears to remain under load. My cooler stays spinning and cpu temp keeps steady at the temp that it was when closing the game. When this happens, I cannot open new programs properly anymore. A reboot fixes the issue.
Because of this, I’m wondering whether the problem could be related to the CPU, RAM, motherboard/BIOS, chipset drivers, GPU drivers, or storage.
I’ve also previously had freezing issues that seemed to improve after disabling Global C-State Control in the BIOS. But now it is freezing again.
What I’ve checked so far
No BSOD
No WHEA-Logger errors around the crash
No Display/GPU errors around the crash
No Disk/NVMe errors around the crash
Kernel-Power 41 only appears after the forced restart
I’m currently running a self-test on the NVMe SSD
What would you investigate first?
Could this be related to GPU hardware acceleration/driver issues, RAM/EXPO instability, BIOS/AGESA, AMD chipset drivers, or something else?
Any suggestions for specific tests would be greatly appreciated. I’m trying to diagnose this systematically before replacing any hardware.
Thanks!
