The computer shuts down unpredictably, but it doesn’t fully stop functioning.
I've been facing this problem with my computer recently. I searched around, tried to figure it out as much as possible, but nothing worked. My PC now freezes unexpectedly at random moments—not a full shutdown. I can still move through windows and open some apps like Task Manager, but others such as browsers or games don’t work. Sometimes I notice no issue at all, other times it happens repeatedly whenever I restart the system. Last week it started with two freezes right after each other, then remained unresponsive for 5 to 6 hours before resuming. The pattern isn’t consistent; I can be offline, watching YouTube, or playing a game, and when I try to reboot, everything just closes as if it’s about to shut down, but it doesn’t actually do that. None of the fixes I’ve tried so far have resolved the problem (about two months ago): - Reinstalled NVIDIA driver using DDU because it felt GPU-related. - Formatted all drives and reinstalled Windows fresh. - Updated BIOS on the motherboard. - Checked GPU and motherboard for damage (still struggling). - Ran RAM tests with Windows tools—no errors found. - Performed a CPU stress test for 10–12 hours; the error triggered a freeze. I did another longer test for 16 hours without issues. I’m unsure what else to try or look for. If anyone has any insights, I’d really appreciate it! I’ve recorded the issue in a video here: https://youtu.be/Ocjr6Cbhh9g
System specs:
- MSI x470 Gaming Pro
- AMD 2700X
- 16GB (2x8) 3200MHz G.Skill Trident Z CL14
- GTX 1080TI
- Corsair RM850x
Could be related to RAM instability. Are you testing at 3200 MHz? The 2000-series Ryzen faces issues above 3000 MHz.
The tool performs poorly. For checking RAM compatibility, use memtest. When using XMP, disable it and observe system performance.
I agree, but I've experienced this since the 2700x launch. It seems the problem started after I updated my BIOS and the RAM was running at normal speeds. Not entirely certain about that part, but let's assume it's the cause. Why would something suddenly become an issue when it wasn't before?
Check if you should start with 3200 runs or use normal speeds first.
You could adjust the frequency to 2933 MHz and see if the problem resolves. Testing with MemTest might be useful to confirm stability. For setting speeds, using XMP is recommended rather than relying on presets. Let me know if that works for you. Thanks!
It occurred again while running at normal speeds. I ran the memtest it linked, and it reported 4 errors. It seems like the RAM might be faulty, so I plan to get some new ones soon. Thank you so much for your assistance! Your help means a lot!
