When a PC game crashes on startup, work through the fixes from cheapest to most disruptive: restart and read the error, verify the game files, update the graphics driver, remove overlays and background apps, install the required runtimes, and only then try clean driver installs, hardware checks, or a reinstall. This order solves most startup crashes without wasting hours or wiping anything you do not need to.
The key is changing one thing at a time and relaunching the game after each step, so you learn what actually fixed it. Menu names vary by launcher and Windows version, so confirm the exact wording in your launcher’s support pages if a step looks different on your system.
Step Zero: Gather Clues Before Changing Anything
A few minutes of observation saves a lot of guessing. Note exactly how the game fails, because each pattern points to a different cause.
Read the error message
If a message mentions a missing file, a runtime library, or a graphics device, write it down. Searching the exact wording on the game’s support forum often leads directly to a fix.
Note when it fails
Does it close instantly, show a black screen, freeze at the logo, or crash after a launcher splash? An instant close often points to missing runtimes or corrupted files, while a crash at the logo often points to drivers or overlays.
Check whether anything changed
Think about recent changes: a Windows update, a new driver, a new overlay, a hardware overclock, or a game patch. The most recent change is a prime suspect.
The Troubleshooting Order, Step by Step
- Restart the PC and relaunch. This clears stuck processes and half-applied updates.
- Verify or repair game files. In your launcher, use the verify integrity option for the game. Corrupted or missing files after an interrupted update are a leading cause of startup crashes.
- Update the graphics driver. Download the current driver from the graphics card maker, not through a third-party tool. If the crash began right after a driver update, consider rolling back to the previous version instead.
- Run the game as administrator and check compatibility. Right-click the game executable, open Properties, and try the compatibility tab options. Use these only when needed, since they can sometimes cause their own problems.
- Close overlays and background apps. Disable overlays from chat apps, recording software, performance monitors, and RGB utilities, then relaunch.
- Install or repair required runtimes. Many games depend on Visual C++ redistributables and DirectX components. Games usually ship an installer in their folder, and Microsoft provides current packages on its site.
- Check antivirus and security software. Some security tools block game files. Add the game folder to the exclusions list rather than disabling protection entirely.
- Reset configuration and shader caches. Move the game’s settings file or cache folder aside so the game rebuilds it. Back up first, since saves may live nearby.
- Undo overclocks and memory profiles. Return the CPU, graphics card, and RAM to default settings temporarily. Unstable overclocks often cause crashes that look like software problems.
- Do a clean graphics driver install. Use the option in the driver installer for a clean installation, or a reputable removal utility following its instructions.
- Reinstall the game. If nothing else works, uninstall, delete leftover folders, and reinstall, ideally on a drive with plenty of free space.
Match the Symptom to the Likely Cause
| Symptom | Likely cause | First fix to try |
|---|---|---|
| Closes instantly with no message | Missing runtime or corrupted file | Verify files, install runtimes |
| Error about a graphics device or DirectX | Driver problem or unsupported hardware | Update or clean-install driver; check game requirements |
| Black screen then crash | Overlay conflict or display mode issue | Disable overlays; try windowed mode |
| Crash at the logo or intro video | Shader cache or anti-cheat issue | Clear cache; repair anti-cheat from the launcher |
| Crashes started after a patch | Bad update or mod conflict | Verify files; remove mods |
| Random crashes across several games | Overclock, overheating, or failing hardware | Return to default speeds; check temperatures |
Launcher-Specific and Anti-Cheat Problems
Launcher repair and cache
Steam, Epic, and other launchers each have repair or verify tools, plus caches that can become stale. Restarting the launcher fully, signing out and back in, or clearing its download cache can fix startup problems that look like game crashes. Follow the launcher’s support instructions, since folder locations differ.
Anti-cheat services
Many multiplayer games install an anti-cheat service that must start with the game. If the service is disabled, blocked, or outdated, the game may close immediately with a short message. Reinstalling the anti-cheat component, usually through a repair option in the game’s folder or launcher, often solves this.
Mods, tweaks, and third-party tools
Mods, texture packs, trainers, and tuning utilities can crash a game that otherwise works. Remove them all, confirm the clean game launches, then add them back one at a time.
Windows features that interfere
Controlled folder access, memory integrity, and other security features can block some game files. Do not turn security features off permanently. Instead, check the Windows security history for blocked actions and add a targeted exception if the developer’s support page says it is safe.
Tools That Help Pinpoint the Problem
Windows Event Viewer
Open Event Viewer, go to Windows Logs, then Application, and look for an error entry at the time of the crash. The faulting module name listed there can point to a specific driver, overlay, or library.
Game and launcher logs
Many games write logs in their install folder or in the documents folder. Support staff often ask for these files, so keep them when contacting the developer.
Reliability and temperature monitoring
Windows Reliability Monitor gives a timeline of crashes and software changes. A free temperature monitor shows whether the CPU or graphics card is overheating before the crash.
When the Problem May Be Hardware
Memory problems
Faulty RAM or an unstable memory profile can cause crashes at launch because the game loads large assets into memory. Run the built-in Windows Memory Diagnostic or a dedicated memory tester, and test with the memory profile disabled.
Storage problems
A failing drive or one with almost no free space can corrupt installs. Check the drive health status and keep some free space available.
Power and heat
An underpowered or aging power supply can cause crashes under load, and blocked airflow can cause thermal shutdowns. If other demanding programs also crash, investigate these before reinstalling anything.
A safety note: do not open the PC case while it is plugged in, and discharge static before touching components. If you are unsure, contact a qualified technician.
Keeping It From Happening Again
Once the game runs, a few habits reduce future startup crashes. Keep at least ten to fifteen percent of your game drive free, update graphics drivers when a release fixes problems for games you play rather than every single release, and avoid closing the PC during an update. Create a Windows restore point before major driver changes so you can roll back quickly. If you tune hardware, keep a record of stable settings so you can return to them.
Keep a short note of what fixed each problem. Patterns appear quickly: if overlays or one particular driver version are repeatedly the cause, you can avoid them next time.
Before You Contact Support Checklist
- Record the exact error message and when it appears.
- Confirm your PC meets the game’s minimum requirements.
- Verify game files and update your graphics driver.
- Try launching with overlays and background apps closed.
- Collect log files and the Event Viewer entry for the crash.
- List your Windows version, CPU, graphics card, and driver version.
Common Mistakes
- Changing many things at once, so you never learn which step fixed the problem.
- Reinstalling the game first, which takes hours and rarely addresses drivers or runtimes.
- Downloading driver or DLL files from unofficial sites instead of the hardware maker or Microsoft.
- Leaving an unstable overclock or memory profile enabled while troubleshooting.
- Disabling antivirus entirely instead of adding a targeted exclusion.

Frequently Asked Questions
Why does my game crash right after launching?
Common causes include corrupted files, missing runtimes, outdated drivers, and overlay conflicts. Verify the files first, then update the graphics driver and close overlays.
Should I reinstall Windows?
Almost never as a first step. Reinstalling Windows is a last resort after drivers, runtimes, and hardware stability have been ruled out.
Can a Windows update cause game crashes?
Occasionally, yes. If crashes began right after an update, check the game’s support page for known issues and consider uninstalling the update only if the developer or Microsoft suggests it.
Is it my PC or the game?
If several games crash, suspect drivers or hardware. If only one game crashes, especially after a patch, the problem is more likely the game itself, and checking its official forum or support page for known issues is a good next move.
