Short answer: match your symptom to the cause. If the game closes to the desktop, suspect drivers, corrupted files or overlays. If the whole PC restarts or shuts down, suspect overheating or the power supply. If you get a blue screen, suspect RAM or drivers. Find your pattern below and work the steps in order.
Why your games keep crashing on PC
A crash is your PC protecting itself. Something the game tried to do failed badly enough that Windows pulled the plug. The mistake most guides make is handing you the same fix list whatever happened on screen. The right fix depends on the pattern, so start by naming yours:
- Crash to desktop (CTD): the game closes without warning and you are back at Windows. The PC itself is fine.
- Freeze or lock-up: the picture stops moving and nothing responds, so you have to force the game closed.
- Full PC restart or shutdown: the screen goes black and the whole computer reboots or turns itself off.
- Blue screen (BSOD): Windows shows a blue error screen with a stop code and restarts.
Find your pattern below and work the steps in order, testing the game after each one.
Pattern 1: the game closes to the desktop
A crash to desktop means Windows and your hardware are probably fine. The fault is usually in the game, its files, or something fighting with it in the background.
1. Verify the game files
Corrupted game files are the most common cause of mid-game crashes. On Steam, right-click the game, open Properties, choose Local Files, then click Verify integrity of game files. Epic, GOG and the Xbox app all have a similar repair option.
2. Update your graphics drivers, cleanly
Outdated or corrupted GPU drivers are the next most likely culprit. Download the latest driver from the NVIDIA, AMD or Intel website rather than relying on Windows Update. If crashes started after a driver update, use Display Driver Uninstaller (DDU) to remove the old driver completely before installing the fresh one.
3. Turn off overlays and background apps
Overlays from Discord, the Xbox Game Bar, the NVIDIA GeForce overlay and Steam can conflict with games, especially alongside anti-cheat software. Disable them one at a time and test. Also close background apps that hook into games, such as MSI Afterburner and streaming software, until the crashing stops.
4. Reinstall the Visual C++ redistributables
Many games depend on the Microsoft Visual C++ runtime libraries. If these are missing or damaged, the game can vanish to the desktop without an error. Download the latest redistributables from Microsoft and install them.
Pattern 2: the game freezes and locks up
A hard freeze with no error message often means the game is waiting for something that never arrives: a shader compiling, a file it cannot read, or memory that never gets allocated.
1. Wait before forcing it closed
Some freezes are shader compilation in disguise, especially on a first run or after a driver change. Give it two to three minutes. If the game recovers, let shaders pre-compile in the settings menu when the game offers the option.
2. Check the memory usage
Open Task Manager with Ctrl+Shift+Esc while the game runs. If RAM usage sits at 95 percent or higher, the game may be running out of memory. Close your browser and heavy apps before playing. If the system only has 8 GB of RAM, that is likely the ceiling for modern titles.
3. Scan for corrupted Windows files
Open Command Prompt as an administrator and run sfc /scannow, then DISM /Online /Cleanup-Image /RestoreHealth. These built-in tools repair damaged system files that can make games hang. Restart the PC afterwards and test again.
Pattern 3: the whole PC restarts or shuts down
When the entire computer reboots or switches off, the problem is almost always hardware: heat, power, or an unstable overclock. Take this pattern seriously, because heat and bad power delivery can damage components over time.
1. Monitor your temperatures
Download HWMonitor or MSI Afterburner and watch CPU and GPU temperatures while gaming. Above 90 degrees Celsius on the CPU or 85 on the GPU is a red flag. Dust-clogged fans, blocked vents and dried-out thermal paste are the usual suspects. For a deeper walkthrough, read our guide to fixing an overheating gaming PC.
2. Disable overclocks and XMP profiles
CPU, GPU and RAM overclocks that are stable in benchmarks can still crash specific games, because gaming loads the system in unpredictable ways. Reset CPU and GPU to stock speeds, and in the BIOS set RAM to its default speed instead of XMP. If the crashes stop, you have found the cause.
3. Check your power supply
An underpowered or ageing PSU can drop voltage under gaming loads and force a shutdown. If crashes only happen in demanding games and your PSU is old or borderline on wattage, it deserves suspicion. Give the graphics card its own dedicated power cables rather than daisy-chained splitters. Also check for GPU sag, which can break contact on the PCIe connector.
Pattern 4: blue screen while gaming
A blue screen with a stop code is Windows telling you what failed, so note the code down or photograph the screen before it reboots.
1. Test your RAM
Faulty or unstable RAM is the classic cause of blue screens during gaming. Run the built-in Windows Memory Diagnostic, or MemTest86 for a deeper check. If you enabled an XMP memory profile, disable it first and retest. XMP pushes RAM beyond its rated spec, and many blue screens vanish the moment it is switched off.
2. Do a clean GPU driver reinstall
Corrupted graphics drivers cause many gaming blue screens, often with dxgmms2.sys named as the culprit. Remove the driver with Display Driver Uninstaller in safe mode, then install the latest driver from the manufacturer’s website.
3. Check Event Viewer
Type Event Viewer into the Windows search bar and look under Windows Logs, then System, for critical errors timestamped at the crash. These name the failing driver or component and are what support forums will ask for if you need more help.
General fixes worth trying for any pattern
- Update Windows fully. Install every pending update and restart. Driver frameworks and DirectX components arrive through Windows Update.
- Try a clean boot. Restart with non-Microsoft startup services disabled to rule out a background program. If the game stops crashing, re-enable services in groups to find the conflict.
- Run the game as administrator. Right-click the game shortcut or executable and choose Run as administrator to rule out permission-related crashes.
- Check your GPU undervolt. An aggressive undervolt can cause crashes in demanding scenes. If you undervolted your card, return it to stock temporarily. Our GPU undervolting guide explains how to find a stable setting.
When to suspect the hardware is failing
If crashes happen in every game and none of the software fixes help, test the hardware itself: MemTest86 overnight for the RAM, a GPU stress test such as FurMark for the graphics card, and temperature monitoring throughout. Faults tend to get worse over time, so crashes spreading to more games is a strong signal a component is failing.
Frequently asked questions
Why do my games keep crashing but my PC works fine otherwise?
A driver bug, unstable RAM profile or weak PSU can go unnoticed until gaming loads trigger the fault.
Can low RAM cause games to crash?
Yes. When a game runs out of system RAM, it can crash to the desktop or freeze. 16 GB is the comfortable standard for modern titles. Closing background apps before playing often helps on lower-memory systems.
Why does my game crash without an error message?
Crashes with no error message are usually corrupted game files, a graphics driver problem, or a conflicting overlay or background app. Verifying the game files and disabling overlays are the fastest things to try.
Can overheating cause game crashes?
Yes, overheating is one of the top causes. When the CPU or GPU gets too hot, the PC throttles performance or shuts down to protect itself, which looks like a freeze, a sudden shutdown, or repeated crashes during demanding scenes.
Conclusion
Start with the crash pattern, not a random fix list. A game that closes to the desktop needs driver and file checks, a full PC shutdown needs temperature and power checks, and a blue screen needs RAM and driver attention.
