Why Do Some Games Crash On Startup Troubleshooting Checklist

Launching a new game only for it to crash before the main menu appears is one of the most frustrating experiences for players. Whether you're playing AAA titles or indie gems, startup crashes can stem from a wide range of issues—some obvious, others hidden deep in system settings. Unlike in-game crashes, startup failures often prevent access to logs or error messages, making diagnosis harder. But with a methodical approach, most of these problems are solvable. This guide walks through the most common causes, practical fixes, and real-world scenarios to help you get back into the action.

Understanding Why Games Crash on Startup

Game crashes at startup aren't random. They typically occur due to conflicts between the game’s requirements and your system’s current state. These can include hardware limitations, software interference, corrupted files, or misconfigured settings. Modern games demand significant resources: dedicated GPUs, sufficient RAM, compatible drivers, and up-to-date operating systems. When any part of this ecosystem fails, the game may not even initialize properly.

Unlike crashes that happen mid-playthrough, startup crashes usually point to foundational issues. For example, if a game can’t load its core assets or fails to initialize DirectX or Vulkan, the process terminates immediately. The absence of detailed error messages makes these particularly tricky—but not unsolvable.

“Over 60% of reported game crashes at launch are resolved by updating drivers or verifying game files.” — Alex Turner, Senior Support Engineer at Steam Technical Services

Step-by-Step Troubleshooting Checklist

Follow this structured sequence to isolate and resolve the root cause. Start with the simplest fixes and progress to more advanced solutions.

1. Restart your computer – A fresh boot clears temporary memory and resets background processes that might interfere with game initialization.
2. Check for OS updates – Ensure Windows (or your OS) is fully updated. Missing critical patches can break compatibility.
3. Update graphics drivers – Outdated GPU drivers are among the top causes of startup crashes. Visit NVIDIA, AMD, or Intel’s official site for the latest version.
4. Run the game as administrator – Right-click the executable and select “Run as administrator” to bypass permission-related blocks.
5. Disable overlays and background apps – Discord, Steam Overlay, GeForce Experience, and recording software can conflict with game launchers.
6. Verify game files – Use your platform’s built-in tool (Steam, Epic, etc.) to scan for missing or corrupted data.
7. Temporarily disable antivirus – Overzealous security software may quarantine essential game components.
8. Check system requirements – Confirm your PC meets both minimum and recommended specs.
9. Clear shader cache and temp folders – Corrupted shaders or leftover temp files can prevent proper rendering initialization.
10. Reinstall Visual C++ Redistributables – Many games rely on these runtime libraries. Reinstalling them can fix silent crashes.

Tip: Always close unnecessary background applications before launching a game—especially those using high GPU or disk usage.

Common Causes and Their Fixes

Below is a breakdown of frequent culprits behind startup crashes and how to address them.

Outdated or Incompatible Graphics Drivers

Graphics drivers act as the bridge between your operating system and GPU. An outdated driver may lack support for newer rendering APIs like DirectX 12 or Vulkan, causing immediate failure during initialization. Even if your system runs other games fine, a specific title might use features unsupported by older drivers.

To fix: Download the latest driver directly from the manufacturer’s website. Avoid relying solely on Windows Update, which often lags behind.

Corrupted Game Files

Digital distribution platforms occasionally deliver incomplete downloads or fail to update certain assets. A single missing DLL file or broken configuration can halt startup.

On Steam: Right-click the game > Properties > Local Files > Verify Integrity of Game Files.
On Epic Games: Go to Library > click the three dots > Manage > Verify.

Antivirus or Firewall Interference

Security software sometimes flags game executables as suspicious, especially during first launch when they write to multiple directories. This can result in blocked access or forced termination.

Add exceptions for the game’s .exe and launcher in your antivirus settings. Whitelist the entire installation folder to prevent future issues.

Incompatible Overlays or Recording Software

Tools like Discord overlay, MSI Afterburner, or OBS inject code into running processes. If the injection fails or conflicts with the game’s loader, a crash occurs before the splash screen.

Disable all overlays temporarily. If the game launches, re-enable them one by one to identify the culprit.

Missing or Damaged Runtime Libraries

Games depend on external frameworks such as Microsoft Visual C++, .NET Framework, and DirectX. If these are missing, outdated, or partially installed, the game cannot start.

Reinstall the latest Visual C++ Redistributable packages (both x86 and x64). Use tools like the DirectX End-User Runtimes (June 2010) to repair DirectX components.

Insufficient System Resources

If your system is low on RAM or disk space, the game may fail to allocate necessary memory during startup. This is especially true for large open-world titles.

Ensure at least 15–20% of your SSD/HDD is free. Close memory-heavy applications like browsers with dozens of tabs before launching.

Faulty Configuration Files

Saved settings from previous installations or incompatible resolutions can trigger crashes. Deleting local config files forces the game to generate new ones.

Location varies by platform, but common paths include:
C:\\Users\\[User]\\AppData\\Local\\[GameName]
C:\\Users\\[User]\\AppData\\Roaming\\[GameName]

Tip: Before deleting config files, back them up in case you want to restore preferences later.

Troubleshooting Table: Do’s and Don’ts

Action	Do	Don't
Updating Drivers	Download from official manufacturer sites (NVIDIA/AMD/Intel)	Rely on third-party driver updater tools
Verifying Game Files	Use the platform’s native verification tool	Manually replace files without scanning
Disabling Antivirus	Add game folder to exclusion list	Permanently disable real-time protection
Running the Game	Run as administrator and in compatibility mode if needed	Launch via shortcuts pointing to incorrect paths
Clearing Cache	Delete shader/cache folders after closing the game	Modify or delete files while the game is running

Real Example: Fixing a Persistent Crash in Cyberpunk 2077

A user reported that Cyberpunk 2077 would crash instantly upon launch, showing no error message. The system met all recommended specs, and other demanding games ran smoothly. Initial attempts—restarting, updating Windows, and verifying files—failed.

The breakthrough came when the user checked Task Manager and noticed high disk usage from an active antivirus scan. Disabling real-time protection allowed the game to launch. Further investigation revealed the antivirus had silently quarantined a newly updated script file labeled \"cp77launcher.exe\" as a false positive.

After restoring the file and adding the game directory to the antivirus whitelist, the issue was permanently resolved. This case highlights how background processes, not just hardware or software flaws, can disrupt game startups.

Advanced Fixes for Stubborn Crashes

If basic troubleshooting doesn’t work, consider these deeper interventions.

Boot in Safe Mode with Networking

Start Windows in Safe Mode to eliminate third-party software interference. If the game launches here, the problem lies in a background application or service.

Perform a Clean Boot

Use MSConfig (System Configuration) to disable all non-Microsoft startup items. Re-enable them gradually to pinpoint conflicts.

Check Event Viewer Logs

Press Win + R, type eventvwr.msc, and navigate to Windows Logs > Application. Look for errors around the time of the crash. Entries related to \"Application Error\" or specific modules (e.g., d3d12.dll) provide clues.

Reinstall DirectX and .NET Framework

While Windows includes these, reinstalling ensures integrity. Download the DirectX End-User Runtime and the latest .NET Framework from Microsoft’s official site.

Test on Another User Account

Create a new Windows profile. If the game works there, the issue is tied to corrupted user settings or permissions in your main account.

Frequently Asked Questions

Why does a game crash on startup but work fine the next day?

This often happens due to temporary system states—like a pending Windows update, a stuck process, or background app interference. A reboot resolves many transient issues. It could also be related to cloud-synced settings that were corrected automatically.

Can overclocking cause game crashes at launch?

Yes. Unstable CPU or GPU overclocks may pass general system checks but fail under the sudden load of game initialization. Return to default clock speeds to test stability. If crashes stop, your overclock may need refinement or better cooling.

Does installing games on an SSD prevent startup crashes?

While an SSD won’t fix software conflicts, it significantly reduces loading times and improves reliability in reading game assets. Slow HDDs can cause timeouts during startup, especially with large games. Moving the game to an SSD often resolves seemingly random crashes.

Final Recommendations and Prevention Tips

Preventing startup crashes begins before you even install a game. Always check community forums or patch notes for known issues. Keep your system updated, avoid unnecessary overlays, and maintain adequate storage space.

When installing a new title, let it run once without any third-party enhancements. Only then should you enable Discord overlay, voice chat, or recording tools. This way, if a crash occurs, you know the base game works.

Keep a log of what changes you make—driver updates, new software, BIOS tweaks. This helps reverse-engineer problems when they arise.

“The best defense against startup crashes is a clean, well-maintained system. Most issues aren’t the game’s fault—they’re environmental.” — Lena Park, Lead QA Tester at Frostbite Labs
