Windows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallCrashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteIf VALORANT closes to the desktop during a match, work through compatibility, software updates, graphics settings, and—if the PC is getting hot—airflow checks before making disruptive changes. Riot’s crash guidance covers several kinds of crashes but does not identify one universal cause for mid-match exits, so treat each step as a test, not a diagnosis.
Start by noting what happens when the game closes
Before changing settings, record whether Windows stays open, whether the game freezes first, and whether Windows displays an error or blue screen. Note whether the problem began after a game or driver update, whether other games also crash, and your GPU, driver, and CPU details. These clues can help narrow the next check, but none proves a cause on its own. Riot’s general guide addresses forced closures, launch black screens, immediate post-launch closures, and complete freezes; it does not single out a mid-match cause.

Check that the PC meets VALORANT’s requirements
Compare your system with Riot’s current minimum and recommended PC specifications. The page lists support for SSE 4.2 or AVX and DirectX 11, and requires Windows 10 64-bit build 19041 or later, or Windows 11 64-bit.
Riot’s published specification tiers are 30 FPS minimum, 60 FPS recommended, and 144 FPS high-end. These are hardware-performance tiers, not measured crash rates or promises that a system will remain stable. Meeting the minimum requirements does not establish why a match ended at the desktop.

Update your graphics driver and Windows
Riot notes that graphics drivers include bug fixes and optimizations, and that outdated DirectX or Windows can contribute to crashes or other hardware-interaction problems. Identify your GPU with the Windows DirectX Diagnostic Tool (dxdiag), then get the appropriate driver through the GPU manufacturer’s official channel. Install available system updates through Windows Update. Riot’s crash troubleshooting guide
Use a driver intended for your specific graphics hardware; there is no single driver version that can be recommended for every PC from the available guidance.

Test graphics settings and driver overrides
A profile in your graphics vendor’s control panel can override a game’s own settings. Riot suggests restoring those profiles to their defaults. If the crash continues, test lower in-game graphics settings; its guide also suggests disabling effects such as VSync and anti-aliasing. These are troubleshooting suggestions, not guaranteed fixes. Riot’s crash troubleshooting guide
- Change a small number of settings at a time.
- Write down what you changed so you can reverse it or identify whether the change affected the crash.
- Play normally and see whether the same symptom returns before changing more settings.
Check heat and airflow only if the PC gets hot
If the computer becomes hot during play, check that its vents are unobstructed and that it has room for ventilation. Riot suggests clearing dust that blocks ventilation with compressed air, taking breaks, and limiting FPS to below the average in-game FPS. These steps apply to a heat or airflow concern; they are not general fixes for unexplained software crashes. Riot’s crash troubleshooting guide

Know when a Vanguard-related blue-screen result applies
A Riot Support result about vgk.sys concerns blue-screen errors on Intel 13th- and 14th-generation CPUs. It is not evidence that Vanguard caused an ordinary VALORANT exit to the desktop. Consider that specific issue only if your CPU generation and blue-screen symptom match; the available result does not support broader troubleshooting instructions for other crashes.
Send useful diagnostics to Riot Support if crashes persist
If the game keeps closing after these checks, open a Riot Support ticket and follow the support agent’s request for diagnostic files. Riot’s log instructions describe collecting VALORANT, Riot Client, and Vanguard logs, along with a process list, network information, and a DxDiag report.
