The computer suddenly restarts during normal use: Causes and solutions

Problem
The computer suddenly restarts during normal use. What's going on?

Solution

There may be many reasons why the computer suddenly restarts. The most common reasons and solutions are listed below:

1 . Overheating

• Overheating your computer can cause system instability, resulting in a reboot.
• Check whether the cooling fan in the chassis is running normally and ensure smooth air circulation in the chassis.
• Clean the dust inside the case, especially on the fans and heat sinks.

2. Power supply problem

• Insufficient or unstable power supply will cause the computer to restart.
• Check whether the power socket is securely connected and make sure the power cord is not damaged.
• Try replacing the power cord or power supply.

3. Hardware failure

• Hardware failure, such as memory module failure, graphics card failure or motherboard failure, may cause a restart.
• Unplug and unplug hardware components one by one, such as memory modules, graphics cards, etc., and restart the computer to identify faulty components.
• Replace faulty hardware components.

4. Driver issues

• Outdated or incompatible drivers can cause system instability, resulting in reboots.
• Update drivers for graphics cards, motherboards and other hardware.

5. System file damage

• System file damage will also cause a restart.
• Run System File Checker (SFC): Enter "sfc /scannow" in the command prompt (run as administrator).

6. Malware

• Malware can corrupt system files and cause a reboot.
• Run an anti-malware scan, such as Windows Defender or third-party antivirus software.

7. BIOS settings

• Incorrect BIOS settings can cause system instability, resulting in a reboot.
• Reset BIOS settings to default values.
