Start by identifying exactly how the failure occurs: a game that never opens, closes to the desktop, stutters, or causes a blue screen or forced restart points to different causes. Check the game’s requirements and files first, then reduce background software and graphics load, verify DirectX compatibility, investigate heat and memory pressure, and treat any Windows-level crash as a separate hardware or operating-system problem. Change one thing at a time so you know which check mattered.
Identify the failure before changing anything
“My game crashes” can describe several different failures. Write down the exact behavior and the point at which it happens before applying a fix. That record prevents you from treating a damaged game file like a failing graphics card.

| What you see | What it usually helps narrow down | First checks |
|---|---|---|
| The game never opens, or stops at “Preparing to Launch” | Missing or damaged files, unsupported requirements, permissions, or a launcher-specific problem | Compare requirements, check storage, and verify the installation through the game platform |
| The game opens and immediately closes to the desktop | Corrupt files, incompatible graphics components, a background conflict, or a title-specific startup error | Record any message, verify files, close unnecessary applications, and check DirectX |
| It crashes after a particular level, menu, or amount of play | A repeatable game bug, memory pressure, heat buildup, a mod, or a driver/API conflict | Note the trigger and elapsed time, remove recent changes, reduce load, and inspect ventilation |
| Low frame rates, hitching, or stutter without a crash | Graphics workload, background processes, low memory, storage pressure, or heat | Close unneeded tasks, lower settings temporarily, and watch whether the problem worsens over time |
| A blue screen, gray screen, or forced restart | A Windows, driver, hardware, or thermal failure rather than an ordinary game crash | Record the stop code and troubleshoot the computer separately from the game |
Also record the storefront or launcher, game version, Windows version, and recent changes. Useful changes include a game or Windows update, graphics-driver update, new hardware, a newly installed application, or a mod. If the title shows an error code, copy it exactly; punctuation and short codes can determine which support instructions apply.

Compare the computer with the game’s published requirements
Open the publisher’s support or store page for the exact edition you own and compare the listed CPU, graphics processor, system memory, Windows version, and storage requirement with your PC. A computer at or just below a game’s minimum specification may fail to launch, not merely run slowly. “Minimum” is a floor for the publisher’s supported configuration, not a promise of a particular frame rate.

Check the requirement for the correct operating-system edition and graphics API. A remastered or upgraded edition can require more memory or a newer graphics feature than the original release. If the game has separate requirements for integrated and dedicated graphics, confirm which adapter the game is actually using in your system settings or manufacturer documentation.
Leave working room on the system drive
A nearly full Windows drive can interfere with updates, temporary files, shader caches, and paging. Microsoft Support gives a general maintenance recommendation of keeping about 10–15% of disk space free, while noting that the exact need varies by configuration. This is not a game-specific frame-rate guarantee; it is a useful condition to check before blaming the game.
Verify files when using Steam
For a Steam installation, use the client’s file check when content may be missing or damaged:

- Right-click the game and choose Properties.
- Open Installed Files.
- Select Verify integrity of game files.
- Wait for the check and any replacement download to finish, then launch the game again.
Steam describes this process as checking whether the installed game files are correct. It is appropriate when a crash follows an interrupted update, a missing-file message, or unexplained startup failure. It does not repair Windows, replace a graphics driver, or validate files installed through another launcher. For another platform, use that platform’s equivalent feature or the game publisher’s official instructions rather than assuming Steam’s procedure applies.
Check for title-specific startup conditions
Some games require a particular runtime, anti-cheat component, account sign-in, or launcher sequence. Do not install random replacement files or registry edits based on a generic error page. Search the publisher’s support page using the exact game version and error text. If the page lists a launcher-specific repair or reinstall step, follow that procedure and note what it changes so you can undo it if necessary.

Why does my PC game keep crashing?
Separate a repeatable game crash from a computer failure
A normal crash usually returns you to the desktop or launcher while Windows remains usable. A blue screen, gray screen, spontaneous reboot, or complete loss of power is a different class of event. Steam’s guidance treats a forced restart or blue/gray screen as a computer problem rather than an ordinary Steam or game failure.
For a desktop crash, note the action that precedes it: loading a save, entering a map, changing resolution, joining multiplayer, or playing for a fixed period. A crash at the same action points you toward a game bug, corrupted content, mod, or title-specific compatibility issue. A crash that appears only after the machine heats up or after other applications consume memory points toward system pressure.
Undo recent changes in the safest order
- Temporarily remove or disable a newly installed mod, overlay, capture utility, or performance tool, following the game maker’s instructions.
- Close applications you do not need, especially browsers with many tabs, recording tools, and other games.
- Return custom graphics settings to a known working preset.
- Verify the game files through the relevant platform.
- Retest before changing a driver or other system-wide setting.
Change only one item between tests. If you change the resolution, update a driver, remove a mod, and reinstall the game together, you lose the ability to identify the cause and may make recovery harder.
How do I fix stuttering or low FPS?
Reduce the workload as a diagnostic test
Lower the game’s resolution and the most demanding graphics options for one test session. If frame rate improves substantially, the workload is involved; that result does not by itself prove that a particular component is defective. Restore settings one at a time to find the option that matters most for this title.
Use the game’s built-in frame-rate display, if available, and observe whether the problem is a consistently low rate or brief hitches. A consistently low rate suggests sustained rendering load. Hitches that coincide with loading, background activity, or an expanding memory footprint suggest a different bottleneck.

Stop unnecessary background work
Steam’s software-performance guidance recommends removing unnecessary startup programs and manually stopping unneeded applications through Task Manager. In Windows, press Ctrl+Shift+Esc to open Task Manager, review the running processes and Startup apps, and close only applications you recognize and do not need for the test. Do not terminate unfamiliar Windows processes merely because they use memory.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
After closing one group of unnecessary applications, launch the game and compare the result. If the hitching disappears, re-enable or reopen items individually to identify the conflict. Keep security software and required drivers running unless their own vendor provides a safe diagnostic procedure.
Use a launch option only when it is relevant
Steam’s performance guidance lists -autoconfig as an initial troubleshooting step for applicable games. Launch options are not universal commands: a title may ignore one, interpret it differently, or require a different option. Use it only when the game’s support guidance or Steam’s instructions indicate that it applies, and remove it after testing if it does not help.
Consider memory pressure
Low available memory can produce repeated frame-rate hitches, especially when other applications remain open. Close unnecessary software, retest, and note whether the problem changes as a session gets longer. If Windows shows low-memory warnings or applications become unresponsive outside the game, treat that as a broader system issue rather than a graphics-setting problem.
How can I check DirectX and graphics compatibility?
Run Microsoft’s DirectX Diagnostic Tool
- Press Windows+R to open the Run dialog.
- Type
dxdiagand press Enter. - Allow the tool to collect information if Windows asks.
- On the System tab, read the installed DirectX version.
- Review the display-related tabs for the graphics adapter information, then compare the result with the game’s published requirements.
Microsoft explains that DirectX supplies components that help software—particularly games—work with video and audio hardware. The version shown by dxdiag is useful evidence, but it is not a complete compatibility test: a game can also depend on a particular graphics feature, driver, or API mode.

Follow the named error’s owner
If the game names a graphics API, driver, or adapter problem, use the graphics-chip manufacturer’s and game publisher’s current instructions for that exact message. Do not apply a universal “clean install,” rollback, or driver replacement procedure without verifying that it matches your hardware and Windows version. A driver change alters the whole system, so record the existing version and create a straightforward way to reverse the change before proceeding.
What if the game gets worse as the PC heats up?
Look for heat and airflow clues
Performance that degrades over time, unusually loud fans, a hot case, stuttering before a crash, or a failure that appears only during long sessions are clues to inspect ventilation. Steam’s hardware guidance identifies poor airflow and dust on vents, fans, and heatsinks as possible contributors to overheating. These clues do not prove that heat is the cause, but they justify a physical inspection.
- Place the computer so its vents are not blocked by a wall, fabric, or a cramped compartment.
- Check visible intake and exhaust openings for dust buildup.
- Observe whether the symptom changes when the system has cooled, without treating that observation as a temperature measurement.
- For a laptop or compact system, follow the manufacturer’s cleaning and service instructions rather than opening it by guesswork.
Clean only when dust is the diagnosed need
An electric air duster or similar PC-cleaning tool can be relevant when visible dust and restricted airflow are present. Use it only according to the computer maker’s safety guidance; avoid forcing debris deeper into the device or spinning fans in a way the manufacturer warns against. Cleaning is not a general solution for missing files, launch errors, or every low-FPS problem, and it does not replace diagnosis of a failing fan or other hardware.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why does my PC restart when I play a game?
Treat stop codes and forced restarts as system-level evidence
When Windows shows a blue screen or stop code, photograph or write down the exact code and any named file. Microsoft explains that a stop error can expose an underlying problem in a driver, hardware, or the operating system. Steam likewise distinguishes a computer blue/gray screen or forced restart from a normal game failure.
Record whether the restart is preceded by rising heat, fan noise, stuttering, or a particular workload. A repeatable stop code after the same change deserves more attention than a one-time desktop crash. Do not infer that the game itself is defective simply because it is the workload that exposes the failure.

Know when to stop experimenting
Repeated blue screens, abnormal temperatures, unexplained power loss, burning smells, visible hardware damage, or failures in several applications are reasons to stop speculative troubleshooting. Contact the PC or motherboard manufacturer, the graphics-card maker, or a qualified technician with the stop code, system model, recent changes, and the conditions that reproduce it. Advanced dump analysis can require specialist knowledge; random registry edits or stress tests can make a hardware problem harder to diagnose.
A reversible troubleshooting sequence
Use this order when you do not yet know whether the cause is the game, Windows, or hardware:
- Define the symptom. Classify it as no launch, immediate desktop exit, in-game crash, stutter/low FPS, blue screen, or restart. Capture the exact message and timing.
- Record the environment. Note the launcher, game version, Windows version, CPU, GPU, memory, storage space, and recent updates, hardware, or mods.
- Check requirements. Compare the publisher’s minimum and recommended specifications with the actual PC, including operating system and graphics features.
- Check free space. Keep roughly 10–15% of the Windows drive free as general maintenance guidance, recognizing that the exact requirement varies by configuration.
- Validate installation files. On Steam, use Library > Properties > Installed Files > Verify integrity of game files. On another platform, use its own supported repair option.
- Reduce conflicts. Close unnecessary applications and review startup items in Task Manager. Retest without changing anything else.
- Reduce rendering load. Lower resolution or demanding settings temporarily and compare the result.
- Check DirectX. Run
dxdiag, read the System tab, and compare the version and display information with the game’s requirements. - Inspect airflow and memory clues. Look for blocked vents, visible dust, heat-related deterioration, and low-memory symptoms. Clean only under manufacturer-safe instructions.
- Escalate system failures. For stop codes, forced restarts, abnormal heat, or repeated failures outside the game, move to manufacturer or qualified technical support.
Common troubleshooting mistakes
- Using a desktop-crash fix for a blue screen. File verification cannot repair a driver, hardware, or Windows failure.
- Assuming minimum requirements guarantee smooth play. They indicate a supported floor, not a promised FPS level.
- Applying Steam instructions to another launcher. Verify the correct platform’s repair feature first.
- Changing several variables at once. One change per test preserves a useful diagnosis.
- Installing random DLLs or registry “fixes.” These can introduce malware or new incompatibilities and are not a substitute for the publisher’s instructions.
- Buying a cleaner or upgrade before finding a physical symptom. Dust and airflow justify safe cleaning; an unspecified crash does not justify a product purchase.
- Opening a laptop or compact PC without guidance. Follow the device maker’s service instructions or use qualified help.
When the game’s support page is the right next step
Use the publisher’s support page when the error is title-specific, appears after a known update, involves an anti-cheat or account service, affects only one save or map, or persists after file verification and basic conflict checks. Include the exact error text, game and launcher versions, Windows version, hardware specifications, reproduction steps, and the changes you already tested. This information lets support distinguish a known game defect from a local configuration problem.

A practical stopping point
If the game still fails after requirements, file integrity, background-process, graphics-load, DirectX, and airflow checks, stop repeating the same fixes. Preserve the error text and test notes, then use the title’s official support channel. If Windows itself crashes, the PC restarts, temperatures are abnormal, or other applications fail, shift the case to the computer, component, or operating-system support channel instead of continuing to reinstall the game.
