Occasional system restart during gameplay or 3D applications
Occasional system restart during gameplay or 3D applications
Hello everyone, my computer has been acting strangely lately—it powers off unexpectedly, sometimes right after launching a game and other times after hours or even minutes. I’m trying to identify the cause of these sudden restarts. Recently, this issue has persisted for about a week. One important detail is that once the PC shuts down automatically, it can take several minutes to restart, sometimes up to ten minutes. When I try to boot it, there’s no response at all.
My system specs are: Processor – Ryzen 9 5950X, Motherboard – MPG B550 GAMING PLUS, Graphics Card – AMD RX 570 8GB DDR5, RAM – 2 x Corsair Vengeance LPX 16GB (1x16GB), 3600MHz, CPU Cooler – Cooler Master MWE 550 80plus 230v, Hard drives – one SSD (Samsung) and two SATA drives, 3.5-inch 5400rpm.
I’m hoping you can help by adding more information or logs. I plan to share the Openhardware monitor logs and will update here once I have a solution. For now, I’ve uploaded them via a Google Drive link: https://drive.google.com/drive/folders/1...sp=sharing.
I’m also experimenting with low graphics settings in games like World of Warcraft to see if it prevents shutdowns, but that doesn’t seem to work. I suspect either the GPU or the power supply unit might be faulty. I’ve tried replacing the power cables, but the issue continues. It’s frustrating because I haven’t changed any hardware since building the PC.
Could anyone shed some light on this? Thanks for your help!
It might be due to trying to find a new SMPS with higher wattage for testing. What confuses me is why the computer doesn’t restart after a shutdown, even when it’s idle for a while or when I unplug and plug it back in. Thanks for your feedback.
It seems your PSU is currently in a recovery mode, which may cause a brief delay before it stabilizes.
This cooler is a compact single tower unit featuring four heat pipes and a 120mm fan. It’s insufficient for heavy workloads like the 5950X under stress. Use tools such as HWMonitor, OpenHardwareMonitor, HWInfo64, or RyzenMaster to check temperatures; you’ll notice spikes until throttling begins. A possible shutdown could result from VRM overheating or PSU issues, both of which delay powering on until temperatures stabilize.
This option fits your budget and is suitable for your CPU. The product page you shared lists the PF240-ARGB as a multi-chamber, addressable RGB cooler that works with Intel and AMD processors, including SST-PF240-ARGB. After six months of gaming—Witcher3, Battlefield 1, 5, and now 2042—I haven’t experienced shutdowns until recently. It shuts down when World of Warcraft is running at high graphics settings.
Using an AIO only exacerbates the VRM situation. You should consider a top down cooler such as the one from Bequiet at https://www.bequiet.com/en/cpucooler/3351. However, I don’t think it’s the VRM problem. Your motherboard has a solid VRM setup, and I’m not sure the CPU is overheating either—especially with an RX 570. My main concern is the PSU, BIOS settings, or RAM configuration. What is your PSU model? Is it MPE-5501-ACABW-EU? What BIOS version is installed? Which RAM model and part numbers are you using?
