Restarting the PC and shutting it down.
Restarting the PC and shutting it down.
Hello, I began noticing repeated and unexpected crashes a few weeks ago. Initially thought they happened only during games, but now they occur at random—during startup, when the PC sits idle, or even after resets. For a short period it seems to work, then problems return. Sometimes my USB devices stopped functioning too. After reading an online post, I tried Hwinfo32 and ran a prime95 test. This was based on a friend’s suggestion that it might be a CPU issue. The crash happened instantly. I shared the log hoping someone could interpret what’s going on, as I’m new to troubleshooting and struggling to make sense of the results. Two recurring errors appeared in Event Viewer: one about the system rebooting without a clean shutdown, possibly due to unresponsiveness or power loss; another about a fatal hardware error, with details pointing to a processor core issue. I’ve also tried a fresh Windows install with the latest drivers and BIOS, tested memtest86 on RAM without errors, checked all connections carefully. Any advice would be greatly appreciated!
Prime95 is outdated and doesn’t evaluate many features. It’s mainly useful for checking thermal issues and if you’re experiencing crashes during boot, the only likely cause is a faulty mount that would trigger every time. For ransomware scenarios, run a memory test—it usually passes cleanly but can be slow. Set it up, execute it, then move on to other tasks. You’ll need several full runs. M.2 drives might also be an issue since they sometimes disable USB ports; however, it’s possible the problem isn’t there despite what you think.
Hello, your question is clear. You're referring to memory tests such as memtest86, and you're curious if a PSU problem might be the cause. Also, you mentioned using three standard SSDs without M.2 cards and are checking for any RAM-related or power supply issues. Thank you for your patience!
You've already verified memory health. Some people run memtest but skip a full test due to its slowness. This leads to the explanation. PSU problems can stem from two main issues: insufficient power output, excessive voltage fluctuations, or spikes in current like with Ryzen 2, higher amperage, or more—causing OCP to trip even when power seems adequate. These situations often result in power loss, sometimes accompanied by an audible click, requiring the machine to restart. The fix for both scenarios involves updated or larger power supplies, with the newer ones supporting atx3.1 standards.
