Are you having issues with your computer rebooting at random? If so, you are not by yourself. This problem has long been bothering many Windows 10 and 11 users.
Your computer may be rebooting at random for a number of reasons. Your power source might be the issue, or it might be a defective part or even a virus. It can be frustrating to cope with, whatever the cause.
If you’re tired of having to restart your computer at random, read our guide below. We’ll walk you through the process of resolving the problem.
Although Windows 11 boasts the best software architecture of any version of Windows, it is not faultless. Without any prior notice or Blue Screen of Death (BSOD) problems, Windows 11 may abruptly restart. Random restarts in Windows 11 are a somewhat uncommon occurrence, and they are more likely to happen on computers with older processors.
However, there are numerous ways you can resolve this problem. There are a few things you can attempt to remedy the issue if your Windows 10/11 machine keeps restarting at random:
- Update your drivers
- Check for hardware issues
- Run a virus scan
- Perform a clean boot
- Reset your PC
- Check your power supply
How to stop Windows from restarting itself randomly
Restarts can only be fixed by systematically ruling out each of the aforementioned problems. Adhere to this check list:
- Verify your connections and power source: There may be something as simple as a slack cord or too much dust obstructing the electricity, but there may also be an inadequate converter, wall socket, or PSU at fault. Make sure your power supply unit (PSU) is rated to handle the wattage of all the components in your computer; the NVIDIA RTX 4090 graphics card can consume up to 450W by itself, not including the CPU. It might be essential to upgrade.
- Watch for overheating, and improve cooling where possible: Use tools like Windows Task Manager to monitor temperatures, and ensure your computer is both clean (inside and out) and well-ventilated. If things seem unexpectedly hot for any reason, you might point an external fan at your PC to help. If you have a tower case, consider upgrades like liquid cooling or more internal fans.
- Install available software updates: By that, we mean wherever possible, not just those in Windows Update. If your machine has a card from AMD or NVIDIA, for instance, use its native Windows app to update graphics drivers.
- Run a malware scan: You can perform free malware scans via tools like Windows Security or Malwarebytes. While we’re at it, you should probably switch on Windows Security’s firewall and real-time protection options if they were previously off.
- Uninstall any new apps or hardware: if restarts began around the same time, you installed them. This doesn’t make sense with a completely fresh PC, naturally.
- Open up your PC and check for damage: if you’ve tried all of the steps above without any luck. You’ll probably have to buy a replacement part if you’re not skilled in PC repair, and in the worst-case scenario, it might be time for a new computer.
- Reset or reinstall Windows: A reset is preferable since it should keep some files and settings intact, but you might be forced to try the nuclear option if problems persist. Back up important files to the cloud or an external drive.
