3. Temporarily Stop your Anti-Virus

There could be a software conflict caused by your device’s activated anti-virus service, so it is recommended to deactivate it temporarily while testing Helldivers 2. Your Windows PC uses the “Windows Defender” by default, but the issue is often caused by third-party antivirus software.

4. Free Up Some PC System Memory

The next effective resolution to underlying issues with Helldivers 2 on your computer is to free up some of your system’s RAM. Overloading the RAM’s capacity with different processes may not leave enough for Helldivers to function properly, causing it to persistently crash or lag on your computer.

If your Helldivers 2 not launching on PC, you need to free up some system memory.

Here’s how to free occupied RAM on your computer system:


  • Open the task manager on your PC (shortcut: Ctrl + Shift + Esc.)
  • Tap on the “Memory” button between the “CPU and “Disk” header.
  • The processes listed at the top consume the most RAM on your PC.
  • Right-click a process and choose “End Task” to free up the RAM. 
  • Repeat for the processes that consume the most memory of the PC.
Browsers and other games in particular consume the largest amount of your system’s RAM resources. You can reduce the RAM utilized by a browser process by reducing the opened tabs or lowering the resource usage of the tabs that are already open. When you’re ready, you might notice a great increase in your Helldivers 2 FPS.

Note: The task manager will display how many tabs of a particular browser are opened right next to the icon.

5. Power Cycle your Gaming Computer

If your Helldivers 2 not launching on PC, consider performing a power cycle of the system. You can address underlying issues with the voltage, system resources, and utilization of the RAM and CPU by temporarily unplugging your computer from the power source.

Power cycling a computer refreshes the system and prevents system bugs that prevent Helldivers 2 launching problems.

Here’s how to conduct a full power cycle procedure on your PC:


  1. Click on the Windows icon on your screen’s taskbar.
  2. Next, select the power icon and choose “Shut Down.”
  3. Once your PC has powered off, unplug it from power.
  4. Wait for 2-3 minutes while the computer is unplugged.
  5. Reconnect your PC’s power cable back into an outlet.
Bonus Tip: Inspect the PC for Overheating!

There’s a strong possibility that your computer’s internal temperatures have reached the overheating margin multiple times if Helldivers 2 isn’t launching.


Efficient methods to reduce your PC’s temperatures are:


  • Power off the PC and wait until it fully cools off.
  • Increase the RPM setting of your case’s fans (drivers)
  • Reduce the voltage setting of your CPU (BiOS)
  • Remove third-party power equipment from the setup.

Computers are particularly susceptible to malfunctioning third-party components that do not administer the power properly, such as strips, power dividers, or outlet connectors. Ensure your computer’s power cable is directly connected to an electrical outlet.


6. Verify Helldivers 2 Files Integrity

There’s a possibility that Helldivers 2’s system files got corrupted as a result of a failed firmware upgrade or improper management of the installation directory. You can rebuild the database of the game by activating a game file verification through the Steam launcher on your PC.


Here’s how to verify the file integrity of Helldivers 2 on your computer:


  • Restart your computer device and launch Steam.
  • Click on “Library” at the navigational panel on top.
  • Locate Helldivers 2 in the side menu by searching.
  • Next, right-click the game and press on “Properties.”
When Helldivers 2 not launching on PC, you need to verify the game files integrity from Steam.
  • Select “Installed Files” → “Verify the Game’s Files.”
  • Wait for 30-40 seconds until the verification is done.
Based on the performance of your disk, the check may last for up to 3-4 minutes. Steam will go through all files of the game, with all 100GBs of the game included, so do not cancel the procedure until the game is ready to be launched.

7. Update your Windows 10/11 System

Helldivers 2’s problem might also be Windows-related and be caused by an outdated version of your operating system. You must maintain the version of your Windows to the latest for all installed games and applications to function properly, without running into issues or errors. You can find more information on rebuilding game data, especially if you have never done this before.

Here’s how to check for a newer version available for your device’s Windows:


  • Go to “Start” → “Settings” on your Windows device.
  • Click “Update & Security” from the side menu listings.

Windows update is an excellent way to fix system bugs and glitches that can prevent Helldivers 2 from launching.
  • Wait until Windows scans for newer available versions.
  • Tap on “Update” to upload the latest Windows version.

Checking for newer Windows updates and downloading the package requires a stable connection with the internet. Ensure your device is securely connected to a network via Wi-Fi or hard-wired Ethernet connection. Updating Windows requires a stable internet connection so we recommend measuring your internet speed and testing if your network is good for gaming.

Alert: Do not power off or reboot your PC while the Windows is updating!
