Postup řešení
- 1 Press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. This runs Windows Memory Diagnostic to test your RAM for errors. Faulty memory is a common cause of unknown traps.
- 2 Press Windows key + X and select 'Device Manager'. Look for devices with a yellow exclamation mark. Right-click them and select 'Update driver' or 'Uninstall device' (then reboot). Incompatible drivers can trigger unknown traps.
- 3 Press Windows key + R, type 'cmd', then press Ctrl+Shift+Enter to open Command Prompt as administrator. Run 'sfc /scannow' and then 'DISM /Online /Cleanup-Image /RestoreHealth' to repair system files.
- 4 Check for overheating: Download a hardware monitoring tool like HWMonitor (free) and check CPU/GPU temperatures. Overheating can cause random crashes. Clean dust from fans and ensure proper ventilation.
- 5 If you overclocked your CPU or GPU, revert to default settings. Restart your PC and press Del or F2 during boot to enter BIOS/UEFI. Load 'Optimized Defaults' and save. Overclocking instability can cause unknown traps.
- 6 If the error persists, perform a System Restore: Press Windows key + R, type 'rstrui.exe', and press Enter. Choose a restore point from before the problem started.
