Question PC restarts alongside Cinebench, Premiere Pro and Spider-Man Remastered?
with the same length and structure:
Hi everyone,
I previously shared a similar situation but didn’t want to bring up an already closed post, thinking I had fixed it. Please let me know if anything needs more explanation.
The issue
I’ve been using my build (details below) without any problems for some time now. Recently, while editing in Premiere Pro, my PC would reboot during rendering or playback of video. This reminded me of an earlier problem where I couldn’t run Cinebench multi-core tests—once I started, the system would shut down immediately. No BSOD or error messages appeared. I fixed the Cinebench issue by updating my chipset drivers. When I faced the Premiere Pro problem, I tried running Cinebench again and the same problems returned. I also noticed this in Spider-Man Remastered; I can’t play the game without it. After the first cut-scene, the PC would restart without any BSOD.
I’ve examined Event Viewer each time, but found only a critical Kernel-Power event (ID 41, category 63).
All other games and high/low load activities, except this one, never triggered the issue. I was using a curve optimizer with negative 5 on all cores, +100MHz CPU boost override, and PBO limits on Auto. So I suspected these settings might be the cause, so I reset the BIOS to defaults first. I also monitored temperatures, which generally stayed between 50°C and 80°C under maximum load, depending on whether I had custom BIOS settings. Based on my specs, what I’ve tried so far and some observations below:
Specs
Mobo: MSI B450M Mortar
CPU: Ryzen 9 5900x
CPU Cooler: NZXT Kraken X62 AIO Water Cooling Unit - 280mm rad (behind the rad in pull config)
GPU: MSI RTX 3090 Ventus 3X 24GB GDDR6X
RAM: Kingston Fury Renegade DDR4 3600MHz CL16 32GB Kit (2x16GB) - XMP Profile 1
PSU: Corsair RM 850 W 80+ Gold Fully Modular ATX PSU initially
Note
- I upgraded to Corsair RM1000x, but that didn’t fix the problem.
Storage: WD S3750 1TB NVMe SSD with Heatsink
Case: NZXT H400i mATX
What I’ve attempted so far
I’ll describe the scenarios where I managed to run Cinebench fully or for short periods, but first here’s a list of all attempts.
Checking Event Viewer for clues (critical Kernel-Power event ID 41, TC 63)
Removing undervolt/OCs, resetting BIOS settings to defaults
Downloading the Cinebench app from the Microsoft Store instead of Maxon
Closing other applications during Cinebench or Premiere Pro runs
Disabling antivirus and other software
Monitoring system signals via HWInfo just before reboots
Adjusting fan curves in NZXT CAM
Updating BIOS to the latest version
Removing old chipset drivers and installing new ones
Testing RAM errors with memtest86 – no issues found on both passes
Turning off memory fast boot
Disabling fast startup in Windows
Switching PSU from RM850 to RM1000x (most tests used the new one)
Testing with PBO on Auto, PBO disabled, etc.
Applying custom PBO limits such as 142 PPT, 90 TDC, 140 EDC / 185 PPT, 125 TDC, 170 EDC
Disabling Global C-State Control
Setting PSU Idle Control to auto, low and normal current
Lowering SoC voltage from 1100 (default) to 1000
Reducing VDDG to 0.950v and VDDP to 0.9v
Testing load-line calibration across various settings (auto, mode 1, 2, 3, etc.)
Using RAM in XMP profile 1, 2, or default (2400MHz)
Applying different Ryzen Master settings (auto overclock, PBO enabled + curve optimizer for -29 on all cores, etc.)
I’ve tried numerous configurations, possibly missing some, and didn’t document every result. Still, in certain cases I managed to run Cinebench fully, render video, or even play Spider-Man Remastered—though crashes followed later. It appears the problem might stem from BIOS settings or drivers. It’s becoming frustrating, so any advice would be greatly appreciated.
What worked (but didn’t fix)
Using default BIOS settings, PBO disabled, and no XMP profile on RAM (2400MHz default) completed a full 10-minute multi-core test. I ran another for 2 minutes and got a crash again—better than being completely stuck.
Enabling PBO in BIOS with custom limits (PPT 160, TDC 115, EDC 140, curve optimizer at -28, +50 MHz boost) still produced a full test but Premiere Pro crashed afterward.
I’m sorry for the confusing post and hope this adds clarity rather than confusion. Thanks!
Do you have any idea of a fix for this problem, or did you discover it by accident?
