How to Fix a Computer That Freezes During Gaming
You are playing a game and the screen freezes — the image stops moving, the audio loops or stutters, and no input works. The mouse does not move, keyboard shortcuts do nothing, and you have to force-restart by holding the power button. Or the game crashes to the desktop, or the entire computer restarts without warning. Gaming freezes are caused by GPU overheating, driver issues, insufficient power, bad RAM, or storage problems. The key is identifying whether the freeze is GPU-related, CPU-related, or a system-wide hardware failure.
Identify the type of freeze
How the freeze manifests tells you what component is failing:
- Screen freezes but audio continues for a few seconds: GPU driver crash or GPU overheating. The graphics driver stopped responding while the audio subsystem kept running briefly
- Complete freeze (no audio, no mouse, no keyboard): CPU overheating, RAM error, or motherboard-level issue. The entire system has stopped processing
- Instant restart (no freeze, just sudden reboot): Power supply cannot deliver enough power under gaming load, or the CPU hit thermal shutdown temperature
- Game crashes to desktop with an error: Software issue — driver bug, game bug, or corrupted game files. The system itself is fine
- Blue screen during gaming: Hardware or driver fault. The stop code identifies the failing component (VIDEO_TGT_INTERNAL_ERROR = GPU driver, KERNEL_DATA_INPAGE_ERROR = storage, IRQL_NOT_LESS_OR_EQUAL = driver or RAM)
Check GPU temperature
GPU overheating is the most common cause of gaming freezes because the GPU runs at maximum load during gaming:
- Install MSI Afterburner (free) or HWMonitor. Run the monitoring tool alongside the game (MSI Afterburner has an in-game overlay that shows temperature during gameplay)
- Watch the GPU temperature during gaming. Most GPUs are safe up to 80 to 85 degrees Celsius. Above 90 degrees, many GPUs start thermal throttling. Above 95 to 100 degrees, the driver may crash or the GPU may trigger a protective shutdown
- If the GPU temperature is too high:
- Clean dust from the GPU heatsink and fans. On desktop PCs, use compressed air to blow through the GPU heatsink fins while holding the fan blades still
- Check that all GPU fans are spinning. A failed fan reduces cooling capacity by half or more
- Improve case airflow: make sure case fans are working and there is a clear path for air from front intake to rear/top exhaust. Remove any obstructions and organize cables away from the GPU
- If the GPU is more than 3 years old, the thermal paste between the GPU chip and heatsink may have dried out. Replacing GPU thermal paste requires removing the heatsink from the graphics card — this is more involved than CPU paste replacement but follows the same principle
Update or roll back GPU drivers
GPU driver issues are the second most common cause of gaming freezes:
Update to the latest driver
- Download the latest driver from NVIDIA GeForce Experience or AMD Radeon Software (or directly from the manufacturer's website)
- Select Custom Installation and check Clean Install (NVIDIA) or Factory Reset (AMD). A clean install removes the old driver completely before installing the new one, fixing corruption and configuration conflicts
Roll back if freezes started after an update
- If freezes began after a driver update, the new driver may have a bug with your specific GPU or game
- Use DDU (Display Driver Uninstaller) to completely remove the current driver: boot into Safe Mode, run DDU, select Clean and Restart, then install an older driver version from the manufacturer's website
- Check forums for your specific GPU model — other users may report the same issue with a particular driver version
Check CPU temperature
Some games are CPU-intensive (strategy games, simulation games, open-world games with many NPCs). If the CPU overheats during these games:
- Monitor CPU temperature with HWMonitor or Core Temp during gaming. If the CPU exceeds 90 degrees Celsius, it is thermal throttling. Above 100 degrees, many CPUs trigger a protective shutdown (instant restart with no blue screen)
- Clean the CPU heatsink of dust and replace thermal paste if the computer is more than 3 to 4 years old
- Check that the CPU cooler fan is spinning at appropriate speed. A CPU cooler running at low RPM under load is either set to a conservative fan curve or the fan is failing
Test RAM
Faulty RAM causes random freezes and blue screens during gaming because games use large amounts of memory:
- Run Windows Memory Diagnostic: press Windows+R, type mdsched.exe, select Restart Now. The test runs during boot
- For a more thorough test, download MemTest86, create a bootable USB, and boot from it. Run at least 2 complete passes. Any error means the RAM is faulty
- If you have multiple RAM sticks, remove all but one and test. Then swap to a different stick. This identifies which specific stick is bad
- If you recently upgraded RAM or changed RAM configuration, make sure the sticks are in the correct slots (consult your motherboard manual for dual-channel configuration — usually slots 2 and 4 from the CPU)
Check power supply
The power supply must deliver enough wattage for the GPU under full gaming load:
- Check your GPU's recommended PSU wattage (listed on the manufacturer's product page). A GPU that recommends a 650W PSU may draw 300W by itself under full load, and the rest of the system needs power too
- Signs of insufficient PSU: instant restarts during gaming (especially when loading a demanding scene), freezes that only happen during GPU-intensive moments, and the system running fine during normal use but failing under gaming load
- PSU capacitors degrade over time. A 3 to 5 year old PSU may no longer deliver its rated wattage. If the PSU was borderline when new, aging has pushed it below the threshold
- If you recently upgraded the GPU to a more powerful model, the old PSU may not provide enough power for the new card
Check storage drive
If the freeze occurs during loading screens, level transitions, or when the game is streaming new assets from disk:
- A failing or slow storage drive causes pauses while the game waits for data. Install CrystalDiskInfo to check drive health
- If the game is installed on a hard drive (HDD), the HDD may be too slow for the game's asset streaming requirements. Moving the game to an SSD often eliminates loading-related freezes
- Run chkdsk on the drive containing the game: Command Prompt as Administrator, chkdsk X: /f /r (replace X with the drive letter)
Game-specific fixes
Verify game files
- Steam: Right-click the game in your Library, Properties, Local Files, Verify Integrity of Game Files. Steam checks every file and replaces any corrupted ones
- Epic Games: Click the three dots on the game, Manage, Verify
- Other launchers: Most launchers have a repair or verify option in the game's settings
Lower graphics settings
- If freezes happen consistently, the GPU may not have enough VRAM or processing power for the current settings. Reduce resolution, turn off ray tracing, lower shadow quality, and reduce texture quality
- Monitor VRAM usage with MSI Afterburner. If VRAM usage exceeds the GPU's VRAM capacity, the game pages to system RAM, causing severe stuttering and potential freezes
Disable overlays
- Game overlays from Discord, Steam, NVIDIA GeForce Experience, Xbox Game Bar, and other programs can conflict with each other and with the game. Disable all overlays and test. If the freeze stops, re-enable them one at a time to find the conflicting one
Windows and BIOS settings
- Disable Game Mode: Settings, Gaming, Game Mode — try toggling this off. On some configurations, Game Mode causes inconsistent frame delivery and freezing
- Disable hardware-accelerated GPU scheduling: Settings, System, Display, Graphics, Change Default Graphics Settings — turn off Hardware-Accelerated GPU Scheduling. This feature helps performance on some systems but causes freezes on others
- Power plan: Make sure the Windows power plan is set to High Performance (Control Panel, Power Options). The Balanced plan reduces CPU and GPU clock speeds during brief idle moments, which can cause micro-freezes in games
- XMP/DOCP RAM profile: In BIOS, if you have high-speed RAM, make sure the XMP (Intel) or DOCP (AMD) profile is enabled. RAM running at default speed (usually 2133MHz) instead of its rated speed can bottleneck performance and cause stuttering. However, if the RAM is unstable at its XMP speed, it can also cause freezes — try running at default speed temporarily to test
