# Why did TSB crash or close?

If the **Talview Secure Browser (TSB)** crashes or closes unexpectedly during your test or interview, it may interrupt the session or result in auto-submission. This can happen due to system limitations, background conflicts, or security software interference.

## ✅ Common Causes and Fixes

| **What Might Be Wrong** | **What You Can Do** |
| :- | :- |
| System resources (RAM/CPU) are maxed out | Close all other applications before launching TSB. Avoid running screen recorders, IDEs, or browsers. |
| Antivirus or firewall force-closes TSB | Allow **TSB.exe** or **Talview Secure Browser** through your firewall/antivirus. |
| System auto-sleep or screen timeout is triggered | Set your power settings to "Never sleep" and disable screen savers during the session. |
| OS or driver issues | Ensure Windows/macOS is up to date. Restart your device before the test to apply pending updates. |
| Corrupted TSB installation | Reinstall TSB using the official download link from your test invitation. |
| External devices interfere | Disconnect any external displays or input devices (e.g., game controllers, docking stations). |
