Why does SteamVR keep crashing?

Short answer: SteamVR can quit, hang, or fail to start when its tool files, graphics driver, headset connection, or a third-party VR driver/component is interfering. Start with Valve's low-risk checks; if the crash stops in SteamVR Safe Mode, the pattern points to an add-on conflict rather than proving that SteamVR itself is broken.

First identify the symptom

Diagnosis: note when it fails: before the headset connects, immediately after a game starts, or only after playing for a while. Also note whether SteamVR disappears, becomes unresponsive, or shows an error code. A headset that is not detected is a different path from the SteamVR process crashing; check Valve's SteamVR Troubleshooting page for the device-specific branch.

Low-risk checks (in this order)

  1. Restart SteamVR, then Windows. Quit SteamVR fully, start it again, and test the same action. Valve lists restarting SteamVR and Windows among its general troubleshooting steps.
  2. Verify SteamVR's tool files. In the Steam client, open Library, search for SteamVR, then right-click it and choose Properties → Local Files → Verify Integrity of Tool Files. The labels may move in later Steam versions; use the equivalent file-verification command if shown.
  3. Check the graphics driver. Valve specifically recommends checking the graphics-driver version and updating it when necessary. Use the GPU maker's official driver channel for your GPU and restart Windows afterward; do not install a driver package from an untrusted download site.
  4. Check the connection and room setup. Reseat external headset connections without forcing plugs, then retry. If SteamVR opens, run Room Setup again from the SteamVR status window. These steps can separate a tracking/connection problem from a process crash.

Use Safe Mode as a diagnosis

If SteamVR still quits or is unresponsive, Valve documents a Windows Safe Mode test: type Run in Windows Search, open it, and enter vrmonitor://safemode/enable. Safe Mode prevents some third-party drivers and components from loading. If SteamVR works there, disable or remove recently added VR utilities or drivers one at a time, then retest normally. Valve gives Natural Locomotion and LIV as examples of utilities that can conflict in some cases; that is not proof that either one is the cause on your PC. Exit Safe Mode from the dialog above the SteamVR status window.

When repair is justified

Repair: use the error-specific path only when the symptom points to it. Valve's Error 100 guidance says a wrong SteamVR installation path can leave configuration/log paths pointing to nonexistent directories. Before changing files, close SteamVR and Steam, and avoid deleting anything unless you have identified that path problem. Valve's documented locations are ...Steam/steamapps/common/SteamVR/bin/win64 (the vrpathreg tool) and user/AppData/Local/openvr (the openvr.vrpath file). If you cannot confidently identify the correct drive and directory, stop and use Steam Support rather than guessing.

As a last resort, Valve's same guidance describes uninstalling SteamVR from the Steam client's Tools list and reinstalling it. This changes local program files and may not fix a driver or headset problem, so do it only after verification, driver checks, Safe Mode, and path diagnosis. Do not factory-reset a headset or alter firmware to troubleshoot a Windows SteamVR crash.

Version and compatibility notes

Menu names and driver behavior can change with Steam, SteamVR, Windows, and headset updates. This page does not claim that a particular headset, GPU, wireless streamer, or third-party utility is compatible; check that product's current official requirements. For performance symptoms that look like stutter rather than a process crash, see VR stutter and dropped frames. For a headset that vanishes from SteamVR, see VR headset not detected by PC.
