Problem with PC Suddenly Shutting Down
Problem with PC Suddenly Shutting Down
Hello. I recently reassembled my PC using identical components, including a new case, upgraded fans, an AIO cooler, and PSU cable extensions from Asiahorse. During this process, I encountered frequent freezing and crashes. Initially, I thought the issue stemmed from the BIOS failing to recognize the AIO cooler, causing automatic shutdown. However, the problem persisted. I verified that temperatures were normal and the cooler was operating correctly. It appears there’s no power draw exceeding the PSU’s capacity, as CPU and GPU usage stayed well below the 850-watt limit. I replaced the CMOS battery and connected an additional CPU power cable to the top left of the motherboard, resolving the issue for about a week. During this time, I could run demanding applications without problems. Recently, the PC automatically shut down again, though fans continued to spin and lights remained active. I suspect the SATA data cable angle might have caused intermittent issues, but disconnecting it didn’t fix the problem. It’s possible the Asiahorse extensions were faulty. I’m running out of ideas and am seeking advice via Discord. My username is prisque. Please share a video of the crashed state if helpful. My current specs are available here: https://pcpartpicker.com/list/4NyBh7. I’m still trying to understand what’s happening.
You have the same parts you used before, except for the case. It might be an intermittent connection issue. Also, many suggestions mentioned problems with the standoffs on the motherboard. You could rule that out by testing outside the case and checking if the problem continues.
Sorry for the confusion, but an intermittent connection refers to a fluctuating or unstable link. Breadboarding involves building circuits without soldering. Your motherboard standoffs might interfere with proper cooling, leading to freezing issues. If your peripherals and AIO cooler go dark during crashes, it makes sense that something is affecting the system's stability. The only lights that dim are your peripherals and the cooler, while the RAM, fans, GPU, and other components remain active. Your monitor freezes completely when it crashes, which could be related to the same cooling or power issues.
No justification needed. When adjustments are made to your computer or any other device and an issue emerges afterward, it makes sense to link the problem to that modification. Altering the case’s configuration introduces new electrical contacts, which are questionable. An unstable connection is one that fluctuates. This instability may stem from the motherboard’s electrical links. Corrosion on connector pins can contribute to such issues. Ensure all connections are firmly in place. The motherboard is secured within the case using metal supports, which might lead to movement or a short circuit only when the system is warm. It would be wise to begin by assuming your issue began after changes and that linking it to those adjustments is reasonable. If you’re unsure about performing these checks, consider bringing the PC to a professional repair service.
Fixing issues can be enjoyable, but many people lack the necessary parts, testing tools, or time. Repair shops typically provide everything.
