Problem with PC freezing – assistance required for diagnosis
Problem with PC freezing – assistance required for diagnosis
My setup includes an AMD Ryzen 9 5950X processor, a GIGABYTE B550 AORUS PRO V2 motherboard, 128GB RAM, a GIGABYTE GeForce RTX 3070 with GV-N3070EAGLE OC-8GD graphics card, and a Seasonic Focus GX-850 power supply. The problem began roughly two to three weeks ago. Initially, the PC would become unresponsive after a few minutes of booting, even though monitors stayed on with backlighting. After a long break, it returned but froze shortly after startup. A restart sometimes restored normal operation for part of the day.
At first, I thought the RAM might be faulty and ran Memtest86+ overnight. The test finished cleanly with three passes. However, after rebooting, the system would lock up at the Windows login screen. Another restart only got it to the loading circle. I also tried booting into Fedora Linux on a different NVMe drive, which froze at the login prompt, likely before switching to the graphical interface. Booting from a USB stick caused freezing right after entering credentials. Interestingly, leaving the PC off for about ten minutes allowed Windows to restart successfully afterward.
Troubleshooting steps so far: Memtest86+ completed three error-free passes; FurMark stress test ran smoothly; GPU and Prime95 performed well; CPU, NVMe drives, and RAM were re-seated without visible damage. The OS is stable on Fedora Linux as well.
What I’ve noticed is that the PC freezes more when idle or under light load. Running benchmarks or stress tests usually stabilizes it afterward, allowing hours of normal use. When idle, it tends to freeze. It seems testing helps the system warm up and regain functionality.
Anyone have ideas? Could thermal issues, power supply problems, or something else be responsible? Your insights would be really helpful!
It occurs mainly when the system is inactive or under light usage. Disabling Core parking would likely affect performance or data handling.
Yeah, but this "while" is undefined. It can be a few minutes to about 1-2 hours. But when I have any kind of load, everything is fine. You know, I run in OCCT every Test, no error, no freezes, nothing. But 15 Minutes after I finished the last test, the PC rebooted. Currently it's 50/50, if the PC just freezes or if it reboots without BSOD. I tried disabling Core Parking, it had no results.
