Common Causes of Call of Duty Restart Loop

Before jumping into the fixes, let’s first look at the most likely culprits behind Call of Duty repeatedly restarting your computer:

  • Outdated BIOS – An outdated motherboard BIOS version is a very common reason for instability and crashes with new hardware and games. Many users fixed constant Call of Duty restarts by updating to the latest BIOS.
  • CPU/GPU Overheating – High temperatures can cause automatic shutdowns as a safety precaution. Use monitoring software like HWMonitor to check if your CPU or GPU is overheating when launching Call of Duty.
  • Power Supply Issues – An inadequate or failing PSU can cause restart loops under heavy gaming loads. Make sure your PSU has enough wattage and test it with tools like Furmark.
  • Game File Corruption – Damaged or missing game files can lead to crashes on launch. Validate and repair the game files through Battle.net or Steam.
  • Windows System File Corruption – Key Windows system files may have become corrupted, triggering the restart. Use DISM and SFC commands to scan and repair system files.
  • Windows Update Problems – Buggy Windows updates are a common source of instability. Try rolling back recent updates or do a clean install of the latest version.
  • Driver Conflicts – Outdated or incompatible drivers can cause conflicts and crashes. Update GPU drivers and chipset drivers to the latest available versions.

Now let’s go through each of these potential causes and solutions in more detail…

Follow these steps to troubleshoot and resolve Call of Duty repeatedly restarting your computer:

1. Update Your Motherboard BIOS

An outdated BIOS is one of the most common culprits behind game crashes and instability with new PC builds.

Here’s how to update your motherboard BIOS to the latest version:

  • Go to your motherboard manufacturer’s website and find the support page for your specific model.
  • Download the latest BIOS version – make sure you get one marked as stable/non-beta.
  • Follow the instructions to flash the BIOS update from within your UEFI BIOS setup.
  • After updating, load optimized default settings and re-enable XMP if you use high speed RAM.

Updating to the newest stable BIOS can significantly improve stability and compatibility with new CPUs and games like Call of Duty. Give it a try!

2. Monitor Your CPU and GPU Temperatures

Excessive heat can force PC shutdowns to prevent damage. Use hardware monitoring software like HWMonitor or HWInfo64 to check your component temperatures.

Launch Call of Duty and monitor the temps as it starts up and restarts your system. Look for any spikes or values above 80-90°C, which indicate overheating.

If thermals are high, improve cooling – clean dust from your PC, ensure fans are running properly, re-apply thermal paste between the CPU and cooler, or upgrade your CPU cooler.

Keeping your hardware cool will help eliminate temperature-related crashes while gaming.

3. Test Your Power Supply with Stress Tools

If your power supply lacks enough wattage or has issues delivering stable power under heavy gaming loads, it can cause random restarts.

Test your PSU using tools like Furmark to stress the GPU and Prime95 for the CPU. If your system restarts or becomes unstable, the PSU likely needs replacing.

Also make sure to use a high-quality PSU from reputable brands like Corsair, EVGA, or Seasonic. A cheap generic PSU is more prone to failure.

4. Validate and Repair Call of Duty Game Files

Corrupted or missing game files can result in crashes on launch. Validate and repair Call of Duty through the Battle.net app or Steam:


  1. Open the Battle.net app and select Call of Duty
  2. Click Options and select “Scan and Repair”
  3. Wait for the scan to complete and restart your PC
Validate and Repair Call of Duty Game Files


  1. Right click on Call of Duty in your Library and go to Properties
  2. Go to Local Files tab and click “Verify Integrity of Game Files”
  3. Let Steam scan and download any missing files, then restart

Repairing the files can fix crashes caused by file corruption.

5. Use DISM and SFC to Repair System Files

Key Windows system files may have become corrupted and lead to instability or crashes. DISM and SFC are built-in utilities to scan and restore damaged system files.

To run DISM and SFC:

  1. Search for Command Prompt, right-click it, and Run as Administrator
  2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter
  3. Type SFC /SCANNOW and press Enter to start the system file scan
  4. Restart your PC once both utilities complete to apply the fixes

Run DISM first, followed by SFC, to fix any corrupted system files causing problems.

6. Roll Back or Clean Install Windows

Recently installed Windows Updates can sometimes contain buggy drivers or code that destabilizes systems.

If the issues started after a Windows Update, try rolling back to a previous restore point before the updates.

Alternatively, do a clean reinstall of Windows 10 to start fresh. Back up your data first, then go through the clean install process. Make sure to reinstall chipset drivers after.

A clean Windows 10 installation can eliminate any accumulated OS issues causing crashes.

7. Update Your GPU and Chipset Drivers

Outdated or incompatible drivers are a common source of game crashes and BSODs.

Go to your GPU (Nvidia or AMD) and motherboard manufacturer websites and download the latest drivers available for your hardware.

Use a utility like Display Driver Uninstaller (DDU) to completely remove existing GPU drivers before installing new ones.

Keep your drivers updated to prevent any driver-related conflicts and instability.

After trying all these troubleshooting steps, Call of Duty: Modern Warfare 2, Warzone 2, or any future Call of Duty should launch without restarting your PC constantly.

No more restart loops or crashes. Just smooth, uninterrupted gaming. Let us know if any of these solutions fixed the issue for you!
