Enter Safe Mode, Cancel Automatically Restartīoot PC to Safe Mode, open sysdm.cpl, uncheck "Automatically restart". Type troubleshoot in search > Select "Troubleshoot". Run Command Prompt as administrator > Enter: shutdown /s /f /t 0. It takes time and patience and you will be there a while isolating the cause.Open Power & sleep settings > Additional power settings > Choose what the power buttons do. I find the causes are heat, power, hardware and software in that order, which is why I troubleshoot them in that order. Perform a system restore if all else fails.Īs you can see, there are a lot of factors in troubleshooting a computer that shuts off randomly.Uninstall any recently installed software or apps.Check Event Viewer to any major warnings or shutdown messages and take appropriate action.Temporarily remove any monitoring software or fan management software you may be using.Check your BIOS version and update if necessary.Upgrade Windows and perform manual updates on all major drivers.If the computer remains stable it could be something else. If the computer shuts down, the issue is in Windows core. Play a movie or run a simple browser game to get it working and monitor. If it seems to be none of those and you use Windows, reboot into safe mode. Perform all the steps above for heat, power and hardware. However, if you use Windows, all bets are off. Usually, a software glitch would trigger a reboot rather than a shut down. It is rare that software or your OS would cause your computer to shut down randomly. If the computer remains stable, whatever you moved or removed is what is causing the instability. Perform that last swap again to make sure it wasn’t a one-off. It is likely that your computer will shut off again. Make a note of what hardware was where and undo that final change. If your computer stops shutting off randomly, look at the last change you made. Switch RAM slots and sticks and monitor.Remove the graphics or audio card before switching on again. If you use external audio and/or graphics and you have onboard, temporarily switch to onboard audio or graphics and retest.Replace and try another if the computer shuts off. Remove one PCI card or RAM stick at a time and monitor.Return your BIOS to defaults and return to stock clocks if you overclock.Unless something is obviously smoking, has melted or burned or is otherwise damaged, it is a process of elimination to find the culprit. Usually a computer power supply can cope, but refining that voltage using a power strip lower the stress on that power supply.įaulty hardware is notoriously difficult to troubleshoot but is rarely the cause of random shutdowns. Even in the newest cities, mains voltage fluctuates quite a lot. It not only protects it against those surges but also cleans up voltage from the mains. I always suggest using a surge protecting power strip for a computer.
