Hard crashes and lock-ups on Linux and possibly Windows 10 could indicate hardware issues, such as a failing component.
Hello, over the last year I've experienced these unexplained shutdowns at random times. Sometimes it happens 5 to 8 times daily, other times it can span a week between incidents. Until now, I haven't managed to identify the root cause. I'm running dual-boot between Pop_OS and Windows 10 on my Lenovo Legion, using identical software on both systems. The crashes occur even after a fresh installation of the drive, yet my laptop remains fully operational. It doesn't depend on what I'm doing—whether I'm working on a document, watching a YouTube video, or playing RuneScape. The issues vary slightly each time but are consistently similar. For example: the PC would restart on its own, then freeze for 0.5 to 1 seconds before rebooting again. After about 30 seconds, it would lock up completely, either rebooting itself or requiring a manual restart. My Windows 10 usage is minimal and I haven't encountered many BSODs, though two notable ones stand out: KMODE_EXCEPTION_NOT_HANDLED and HYPERVISOR_ERROR. In both cases, my other screens became corrupted (like a deep fry), and there was a persistent low-frequency buzzing or sound from the speakers. I'm seeking a solution or guidance. I suspect it might be hardware-related, but I don't want to make random changes. I'd prefer certainty before replacing parts. I can't reproduce the problem with stress tests—using MemTest64 didn't yield results. After several tests, I cleaned up and ran SSD swaps, but nothing changed. Current components include: Ryzen 3700X with cooler, EVGA GeForce 2060S, MSI x570 graphics card, Intel 665p 1000GB drive, Windows 10, Linux drive, Crucial P2 M.2, Hyperx 16GB 3200MHz, Corsair HX750 750W PSU, Akasa USB 3.0 PCIe card. Past contents: Corsair 32GB 3200MHz (failed), faulty memory detected by Memtest64, AVM Live Gamer HD not in use, EVGA 750BQ 750W PSU, power issues suspected but ruled out with other fixes like unplugging devices. I also removed the RGB strip from Aliexpress, had a DVD drive disconnected during troubleshooting, swapped parts, and replaced several peripherals (keyboard, mouse, fans, speakers). Additional items included USB thumb drives, a YubiKey, SD card reader, and various software like Modecom, Logitech, Samsung soundboards, and more. Journal files are present but not directly relevant to the issue. What should I do next?
Looking for guidance? I'm here to help you find the right path.
I recently purchased the Ryzen 5 4600G for testing purposes. I have thirty days to return it, and I plan to clean my original cooler thoroughly since I used it before. I’ll keep the new CPU just in case it works out for my girlfriend’s PC. I’ll let you know after the trial period or if the issues persist. Long-term observation shows the problem was likely the CPU itself. After about a month, I haven’t encountered any crashes or unusual behavior—only minor, expected issues like Gnome problems. I’m curious to understand exactly what caused it. It seemed to worsen over time, but it wasn’t present at the time of purchase. All benchmarks, tests, and stress tests I ran didn’t reproduce the issue. Perhaps one day I’ll figure it out.
