You can be confused and frustrated when you start a game and Windows suddenly restarts. Don’t worry, you’re not alone. There may be reasons for this problem. There may be a virus on your computer. Make sure you have updated your antivirus software.

Another reason is if your power supply does not provide enough juice. Make sure that your power supply is adequate for the power task of your graphics card. Assuming you have a newer GPU, you’ll probably have just under 500 watts of power to worry about. The energy consumption is indicated with the specifications of your graphics card. Depending on your other equipment, you may even need a more powerful power supply than the specified requirements. The third reason why your PC may restart by itself is overheating. If the CPU gets too hot, your PC will shut down to save money. In this case, the first thing to do is to clean up. Make sure all your fans are running and clean the dust in your PC with a fan or compressed air.

Methods to follow when your computer restarts while you are playing:

Check If Sleep Mode is Enabled

1. Open Power Options, locate your current plan and click the Edit Plan Settings button.
2. Once you have done this, you will find the Put the computer to sleep option and select any value except Never.
3. Click Save Changes and your problem should be solved.

Change Your Power Settings

• Type “Control Panel” in the search field and press Enter.
• Set the Control Panel display to Large Icons and click Power Options.
• Click on Change plan settings.
• Click Change Advanced Power Settings.
• Locate and click on Processor Power Management > Minimum Processor Status.
• Set the number to low, for example 5% or 0%, then click OK.
• Save the changes and restart your PC.

Updating Graphics Drivers

1. Download and install DDU (Display driver uninstaller) from the official website.
2. After installing Display Driver Uninstaller (DDU), start your computer in safe mode. You can read our article on how to start your computer in safe mode.
3. After starting the DDU, select the first option “Clean and restart”. This will completely uninstall the current drivers from your computer.
4. After uninstalling, start your computer normally without failure mode. Press Windows + R, enter “msc” in the dialog box and press Enter. Right-click on any free space and select “Search for hardware changes”. The default drivers will be installed.
5. Try to start the game and see if it solves the problem.
6. In most cases, the default drivers will not work for you, so you can either install the latest drivers via Windows Update or browse your manufacturer’s website and download the latest drivers.
7. After installing the drivers, restart your computer and check that the problem is solved.

Perform System Restore

• Right-click (or hold down the Start key) and select Control Panel.
• Search Control Panel for Recovery.
• Select Recovery > Open System Restore > Next.
• Select the restore point related to the application, driver or problematic update, then choose Next > Finish.
