Why does my computer turn off after Windows boot?

Faulty RAM often causes windows shutdowns after boot. Use a tool like ‘MemTest86’ to check your memory modules. If errors are found, you may need to replace the defective RAM sticks. Properly functioning RAM is crucial for system stability and can prevent such issues.

A faulty power supply unit might be your issue. Over time, PSUs can degrade and become unstable, leading to shutdowns. If you have access to a working, compatible PSU, try swapping it to see if the problem resolves. Alternatively, you could take your computer to a professional for testing.

Bad drivers can cause shutdown issues like you’re describing. Try booting your computer into Safe Mode by pressing F8 during startup. If the shutdown does not occur in Safe Mode, you are likely dealing with a driver conflict. Update your drivers, particularly for critical hardware like the graphics card and motherboard. It should solve the issue if driver conflicts were the root cause.

Software conflicts could be causing your computer to turn off after booting. Perform a clean boot by disabling all startup items and non-Microsoft services. Restart your computer and monitor if the shutdown persists. If it doesn’t, then one of the disabled services or startup items is causing the problem. You can re-enable them one at a time to find the culprit.

Malware can sometimes cause unexpected shutdowns. Run a full scan using a reliable antivirus program to check for any infections. If malware is found and removed, it may resolve the issue. If no malware is detected or it doesn’t fix the problem, consider using System Restore to revert your computer to a time before the issue started.

Managing power settings in Windows can sometimes correct this issue. Navigate to ‘Control Panel,’ select ‘Power Options,’ and switch to a different plan like ‘High Performance.’ Adjust any individual settings that might be contributing to the shutdown. It could be a simple fix if the shutdown is connected to power management settings.

I’ve seen this issue resolved by resetting the BIOS settings. Enter your BIOS during startup (usually by pressing Del, F2, or Esc) and restart with default settings. Incorrect BIOS configuration, especially with power management settings like ACPI, can sometimes lead to shutdown issues.

In my experience, corrupted system files can cause the computer to shut down unexpectedly. Open the Command Prompt as an administrator and run ‘sfc /scannow’. This command initiates a system file check and repairs any corrupted files that could be causing your issue. Give your computer a reboot afterward to ensure any changes take effect.

I had a similar problem before, and the culprit was overheating. The computer might be shutting down to protect itself from thermal damage. Check inside your case for dust and clean it out. Make sure your fans and heat sinks are functioning properly and that there is no dust buildup blocking airflow. If the overheating problem persists, you might need to replace the thermal paste on your CPU.
