The workstation frequently stops unexpectedly, with no clear cause identified.
Hello everyone, I’m experiencing some issues with my computer. The screen goes dark suddenly, and the fans begin spinning at their normal speed. The machine doesn’t completely stop, but it’s unresponsive—no signals, no output, except the fans. Even the power button on the front case won’t work. This happens intermittently, usually every other day, sometimes a couple times a day, and occasionally for a short time. There’s no clear cause yet. It can occur while I’m working, during games, or even when just opening a web browser or browsing after logging in. It seems more frequent when I’m using software like 3dsMax or CAD, but it also happens when nothing is open and I’m just watching the desktop right after turning on. It appears to be more common during work sessions, though it might be influenced by how I use the system. I’ve tried various troubleshooting steps: ran antivirus scans, checked disk health, performed a system file check, updated drivers, cleaned the registry, used memtest, and verified CPU temperatures. All tests came back normal. I also updated UEFI drivers recently. No logs in Event Viewer, except one after a reboot indicating an incorrect shutdown. The GPU temperature readings stayed within normal ranges, and I haven’t logged any GPU data during these incidents. I’ve cleaned the system, reinstalled Windows, and switched OS versions, but nothing has changed. I’m unsure about power supply issues now, as I don’t have specific details. I’m seeking advice from more experienced users to figure out what might be causing this problem before I start testing each component one by one. This process is quite stressful, especially since the PC was a used model and I can’t easily get professional help nearby. Thank you for your support.
I’ve reviewed the troubleshooting steps you’ve already taken. Here are some recommendations:
Use HWMonitor or similar tools to monitor temperatures for all parts.
Check drives with CrystalDiskInfo.
Run the following commands in an admin terminal:
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth sfc /SCANNOW
If you have extra expansion cards, remove them and test again.
You noted multiple monitors. Windows has a known issue where mismatched scale settings can cause random crashes—especially Explorer or the whole system.
Another trial is attempting to launch the problematic file on a Linux system. This helps determine if the issue comes from hardware or software. You can locate numerous free Linux LiveCDs or DVDs that fit onto a USB stick. This process won’t interfere with your existing Windows installation since it won’t modify it; you simply boot from the USB drive.
I believe it only counts if the initial test didn’t work (pinpointing the problematic stick or slot), though someone might point out an error.
