The computer has stopped unexpectedly, and I've done all possible things to fix it.
The computer has stopped unexpectedly, and I've done all possible things to fix it.
The system will power down suddenly—no lights, no blue screen—and this seems to occur more often when I’m not actively using it (like browsing the web). Over the past year I’ve tried fixing it by swapping the motherboard, CPU, and power supply. None of those changes resolved the problem. After replacing the PSU five times, the issue stopped for a while, but then it returned every 10 to 30 minutes. I switched to a different brand’s PSU (Corsair) without success. I also changed the GPU, case, RAM, and SSD today, yet the issue persists, sometimes even with the GPU. I connected the PSU directly or through a UPS, tried various power outlets, and even used another wall socket. I’m running out of ideas and feel stuck. If anyone has suggestions or insights, it would be really helpful. I’m almost considering selling my parts on the marketplace and buying a prebuilt unit for the 4090 CPU (AMD Ryzen 7 7800X3D).
I recommend checking your operating system might be contributing to the problem since you haven't explored that. Consider using a Linux live USB to verify whether the issue stems from hardware or software. If the computer continues to power off or shut down, proceed with the RMA or part replacement process. Reset the motherboard to its original settings and turn off any overclocking features. Ensure the RAM is properly seated, all cables are securely connected, and consult the user manuals thoroughly. Verify there are no ground connections that could activate your home safety switch. If your home is outdated without a safety switch, place a voltmeter at metal surfaces near the case and power supply; it should read zero volts. Boot the system with only essential components—motherboard, CPU, and one RAM stick. Use the live USB if you have integrated graphics, or find an alternative graphics card if needed. Begin troubleshooting by testing the RAM first, then the CPU.
I didn't mention in my initial message that I attempted to run with XMP disabled and PBO turned off. I also tried using just one stick of RAM. I'm considering reverting the BIOS to an earlier release, though I'm concerned about a possible hard restart during the update. I plan to run memtest86 to gather more details, but after failing to replace the RAM successfully, I suspect another issue exists. Regarding alternative operating systems, I tried a fresh Windows installation on a separate SSD, but it experienced a hard shutdown during setup. Thank you for the advice and solutions you shared.
Event 41 is here for you, but it doesn’t clarify much beyond power loss.
