What Software Fixes Any Issue With Any Game on PC? 10 Tested Free Tools
Your game crashes right before you save. Your FPS drops to single digits mid-match. Or you get a weird error code that makes zero sense. If any of that sounds familiar, this guide is for you.
PC gaming is amazing. But PC games break. That is just the reality. And when something goes wrong, most people waste hours looking for answers that never help.
Here is the truth: uncovering a simple software egg or hidden fix can solve most PC game problems. You just need to know which tool to use for which issue. That is what this guide covers.
We researched over a dozen tools and picked the best ones based on how well they work, how easy they are to use, and whether they are free. Below is the complete list, plus a quick guide on when to use each one.
Why Do PC Games Break in the First Place?
Before you fix anything, it helps to know what caused the problem. Most PC game issues fall into one of these categories:
- Outdated or broken drivers: Your graphics card needs fresh drivers to work properly with newer games.
- Missing system files: Games need DirectX and Visual C++ packages installed just to start up.
- Corrupted game files: A failed update or sudden shutdown can damage the files your game depends on.
- Overheating hardware: A hot GPU or CPU slows itself down on purpose to avoid permanent damage.
- Too many background apps: Other programs eat up RAM and CPU power that your game needs.
- Malware or junk buildup: Hidden threats and old leftover files slow your whole system down.
- Overlay conflicts: Apps like Discord, Xbox Game Bar, and Steam overlay can crash games when they all run at the same time.
Each problem needs a different fix. That is why this list gives you a specific tool for each type of issue.
The Best Software to Fix Any PC Game Issue
1. Driver Booster: Fix Outdated or Broken Drivers
Best for: Game crashes, black screens, stuttering, and low FPS caused by old drivers
Your graphics card driver is the number one cause of PC game problems. When it is old or broken, games crash, freeze, or refuse to launch. Driver Booster scans your entire PC and finds every outdated driver in seconds. Then it updates them all with one single click.
It covers your GPU, audio card, network adapter, and more. The free version handles most needs. The paid Pro version updates drivers faster and includes some gaming extras. For most people, free is more than enough.
This should be the very first tool you try when any game stops working the way it should.

2. DDU: Do a Clean GPU Driver Reinstall
Best for: Crashes that keep happening even after updating drivers, leftover driver conflicts
Sometimes updating a driver is not enough. Old driver files stick around and cause hidden conflicts. DDU (Display Driver Uninstaller) wipes your GPU driver completely clean so you can start fresh.
The steps go like this: Run DDU in Safe Mode, remove your current GPU driver fully, restart your PC, then download the latest driver straight from NVIDIA or AMD. Many stubborn crash problems disappear after this step alone.
It sounds like a lot, but the process takes around 15 minutes. The official DDU page walks you through every step clearly.

3. DirectX Repair Tool: Fix DirectX Errors
Best for: Errors like “DirectX encountered an unrecoverable error” or “d3dx9.dll not found”
Almost every PC game uses DirectX. It is a group of files that help your game communicate with your graphics card and sound system. When DirectX has missing or broken files, games will not start at all.
Microsoft’s DirectX End-User Runtime installer finds and replaces broken DirectX files in just a few minutes. It is completely free and small to download. If your game throws a DirectX error on startup, run this tool first before trying anything else.

4. Visual C++ Redistributables: Fix Runtime Launch Errors
Best for: “VCRUNTIME140.dll not found” errors and games that crash instantly at launch
Game developers build their games using Visual C++ tools made by Microsoft. When your PC is missing these files, games simply will not open. No error message, no warning. They just close right away.
The fix is easy. Download all the Visual C++ Redistributable packages from Microsoft. Install the 2010, 2012, 2013, and 2015 to 2022 versions. Restart your PC afterward. A shocking number of mysterious launch errors disappear after this one step.
It is not exciting, but it works more often than you would ever expect.

5. Launcher Repair Tools: Fix Corrupted Game Files
Best for: Crashes mid-game, missing textures, errors after updates, infinite loading screens
A failed update, a sudden shutdown, or even a bad download can leave your game files damaged. When that happens, the game crashes in weird ways or will not load at all. Every major game launcher comes with its own repair tool that checks your files and fixes anything broken.
Follow these steps on each platform:
- Steam: Right-click the game, go to Properties, click Local Files, then click Verify integrity of game files.
- Epic Games: Click the three dots on the game, click Manage, then click Verify.
- EA App: Right-click the game and select Repair.
- Battle.net: Click the gear icon next to the game and select Scan and Repair.
This fix is free and already built into the launcher. It takes a few minutes and fixes problems more often than you would think. Always try this before anything else when a game breaks after an update.
6. MSI Afterburner: Monitor and Fix FPS and Overheating Issues
Best for: FPS drops, stuttering, lag spikes, and GPU temperature problems
MSI Afterburner is the most trusted free tool among serious PC gamers. It shows you real-time data for your GPU temperature, FPS, VRAM usage, and CPU load while your game is running.
When your game stutters or drops frames suddenly, Afterburner tells you why. Is your GPU hitting 95 degrees and slowing itself down? Is your VRAM completely full? Is your CPU maxed out? All of that shows up right on your screen in real time.
It works with NVIDIA, AMD, and Intel GPUs. It is completely free. No other tool gives you this level of detail while you are gaming.
Safe GPU temperatures during gaming: under 85 degrees Celsius is healthy. If you regularly hit 90 or above, your PC needs better cooling or a good cleaning.

7. HWMonitor: Catch Overheating Before It Kills Your Session
Best for: Random shutdowns, performance throttling, and hardware crashes during long gaming sessions
If your PC shuts off in the middle of a game, or runs perfectly for 15 minutes and then crashes, heat is almost always the cause. HWMonitor shows you the real temperature of your CPU, GPU, hard drives, and other parts all in one place.
The difference between HWMonitor and MSI Afterburner is simple. HWMonitor covers more parts of your whole system. Afterburner is more focused on in-game GPU performance. Both are free and both are worth having.
HWMonitor does not fix overheating by itself. But it tells you which part is running too hot so you know where to focus your effort: cleaning dust, improving airflow, or replacing dried-out thermal paste.

8. Razer Cortex: Squeeze Extra Performance from Older Hardware
Best for: Low FPS on average hardware, slow game launches, background apps stealing resources
Razer Cortex is a free gaming app that unlocks system potential, much like finding out What is Developer Option in Android Phone? does for mobile gamers. When you launch a game through Cortex, it automatically shuts down background apps and frees up RAM and CPU power. Your game gets more of the system resources it needs to run smoothly.
It will not turn a weak PC into a powerhouse. But for people with average or older machines, it can squeeze out extra frames and make games feel noticeably smoother. It also helps you find game deals and track your play time.

9. Malwarebytes: Remove Hidden Threats That Wreck Your Games
Best for: Unexplained slowdowns, anti-cheat failures, games being flagged as threats, strange random crashes
Malware is a sneaky problem. It runs quietly in the background, eats up CPU power, and sometimes interferes with game files or anti-cheat systems. Many gamers have no idea it is even there.
Malwarebytes finds and removes malware that most basic antivirus tools completely miss. The free version does a full manual scan. You do not need to keep it installed permanently. Just run a scan once a month or any time your games start acting strange without a clear reason.
A lot of gamers are shocked by how much hidden junk shows up on their PCs when they run this for the first time.

10. Windows SFC and DISM: Repair Broken Windows System Files
Best for: Blue screens during gaming, serious system errors, problems that nothing else can seem to fix
Sometimes the problem is not the game at all. It is Windows itself. When Windows system files get corrupted, games crash in random and unpredictable ways. Windows has two powerful tools for this: SFC (System File Checker) and DISM.
Run them in this order:
- Press the Windows key, type cmd, and right-click to run it as Administrator.
- Type sfc /scannow and press Enter. Let it finish completely.
- Then type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
- Restart your PC when both are done.
These tools are already on your PC. No download needed. They scan Windows for broken files and repair them automatically. If your games keep crashing and nothing else fixes it, always try this before spending money on anything. It is one of the most powerful windows 11 tips and tricks for system stability.
Which Tool Should You Use for Your Specific Problem?
Not sure where to start? Match your problem to the right tool here:
- Game won’t launch at all: Install Visual C++ Redistributables, then run the DirectX Repair Tool.
- Game crashes right at the start screen: Verify your game files through the launcher (Steam, Epic, etc.).
- Game crashes in the middle of a session: Update drivers with Driver Booster, then check temperatures with HWMonitor.
- Low FPS and constant stuttering: Use MSI Afterburner to find the bottleneck, then try Razer Cortex to free up resources.
- PC shuts off while gaming: Check temperatures with HWMonitor immediately. Heat is almost always the reason.
- Games work but PC feels very slow: Run Malwarebytes and close background apps through Task Manager.
- Nothing works and crashes are completely random: Run Windows SFC and DISM, then do a clean GPU driver reinstall with DDU.
Important Tips Before You Download Anything
- Always download from the official website. Every link in this guide goes directly to the official source. Never use random third-party download sites because they often bundle unwanted software.
- Restart your PC after every fix. Many changes only take effect after a full reboot. Do not skip this step or your fix might not work.
- Try the simplest fix first. Verifying your game files takes two minutes and solves a huge number of problems. Always start there.
- Update Windows before anything else. Go to Settings, then Windows Update, and check for pending updates. Many game errors simply vanish after a Windows update.
- Turn off overlays if your game crashes. Discord overlay, Xbox Game Bar, Steam overlay, and NVIDIA GeForce Experience can all conflict with each other and with games. Disable them one by one and test after each one.
- Do not stack up too many of these tools. Running five of them at the same time causes more problems than it solves. Pick one or two and stick with them.
Frequently Asked Questions
Is there one software that fixes every single PC game problem?
No single tool covers every possible issue. But combining Driver Booster, Visual C++ Redistributables, and your game launcher’s own verify tool will solve the majority of problems most gamers ever face. For harder cases, Windows SFC and DISM cover what the others miss.
Are all these tools safe to download?
Yes, as long as you download them from the official websites linked in this guide. All of them are well-known tools used by millions of PC gamers every day. Just avoid searching for them on random download sites because those versions can sometimes include bundled adware or worse.
Do I need to pay for any of these tools?
Most tools on this list are completely free. Driver Booster has a free version that works well for most people. The paid Pro version just adds faster update speeds. Windows SFC, DISM, and every game launcher repair tool cost absolutely nothing.
Why does disabling overlays fix game crashes?
Apps like Discord, Steam, and Xbox Game Bar inject their own code into your running game so they can display information on screen. Sometimes that code conflicts with the game engine. The result is crashes, freezes, or input lag. Disabling these overlays removes the conflict completely.
My game still crashes after trying everything on this list. What do I do?
If nothing here helps, the problem may be with your actual hardware. Failing RAM, a dying GPU, or an underpowered PSU (power supply unit) can all cause crashes that no software can fix. You can test your RAM using Windows Memory Diagnostic, which is already built into Windows. For anything beyond that, a local PC repair shop can run proper hardware-level tests.
How do I know if my GPU is overheating?
Download HWMonitor or open MSI Afterburner. Play your game for around 20 minutes, then check the temperature reading. If your GPU regularly hits 90 degrees Celsius or above, it is running too hot. Clean the dust out of your PC, make sure the fans are spinning, and check that your case has decent airflow.
Final Thoughts
PC game problems are frustrating. But almost every single one of them has a fix. You just need the right tool for the right problem.
Start with the basics. Verify your game files through the launcher, update your drivers with Driver Booster, and install the latest DirectX and Visual C++ packages. Those three steps alone will solve the majority of game issues most people ever run into.
If the problem is more stubborn, use HWMonitor to check for overheating, run Windows SFC to repair system files, or use DDU for a clean driver reinstall. And if something invisible is dragging your system down, Malwarebytes will find it fast.
