A newly assembled PC unexpectedly shuts down during gaming and streaming sessions.
A newly assembled PC unexpectedly shuts down during gaming and streaming sessions.
I recently assembled my first PC roughly seven months ago. It performs well across various tasks, but it occasionally shuts down unexpectedly during gaming or streaming. Despite trying to fix it, I can’t pinpoint the cause or force a restart. No alerts appear, no BSODs, and no memory logs are present. The problem remains stubborn, even after stress tests and adjustments.
I’ve checked several things: updated drivers, ensured all software is current, verified BIOS versions, monitored temperatures with HWinfo, ran diagnostics on RAM, and even performed a full system reset. I also disabled auto-restart features and enabled memory dumping, but nothing resolved the issue.
Some notes on hardware: I use a Cooler Master H500M ATX motherboard with GIGABYTE Z590 AORUS, paired with an Intel i9 11900k CPU and 64GB of DDR4 RAM. My GPU is an EVGA GeForce 3080 Ti. The PSU is an EVGA Supernova 80+ Gold model, and I’ve had issues with BIOS updates in the past.
I’m trying different configurations—reducing RAM to 32GB or using fewer sticks—but performance isn’t improving. I’m also considering lowering the CPU voltage or clock speed, though my system seems to draw a lot of power.
Event logs show a kernel power event and an ACPI 2 popup, but I can’t confirm what triggered them. I’m still trying to understand why this keeps happening. I’ll keep testing and updating as soon as the new PSU arrives. Thanks for your help!
I've experienced frequent random crashes, especially under stress tests. Mostly it seems like a RAM problem, though it can vary. There were times when the system would freeze and lock up, requiring a forced shutdown. After a few instances, lowering my memory resolved the issue. It appears I adjusted it from 3000 to 2666 relative to the XMP profile, not the base speed. My conclusion is that your RAM isn't fully stable, leading to these crashes.
This remark highlights a significant aspect and Brooksie raises a strong observation regarding RAM crashes. You're on the correct path with the approach of testing two sticks. Once you remove both and check the BIOS settings, see if XMP can be enabled. Regardless of its success or not, it's worth swapping the remaining sticks to confirm that the issue lies with the RAM itself.
I’m unsure if your PSU model matches both ends of modular cables, but I’ve heard stories about people swapping the connections accidentally—like labeling one end PSU and the other VGA. It wasn’t what actually happened, just my initial thought.
Sure, I can help with that. The issue you're facing is the same as before.
