Error Code irql-not-less-or-equal — CPU-Z

Postup řešení

1. 1 Restart CPU-Z completely. Close it, open Task Manager (Ctrl+Shift+Esc), find any remaining CPU-Z processes, right-click → End Task. Background processes from previous sessions are the most common cause of startup crashes.
2. 2 Update CPU-Z to the latest version. Open the app, go to Help → Check for Updates (or download the latest installer from the official website). Updates fix known bugs and compatibility issues.
3. 3 Reset CPU-Z settings. Navigate to %APPDATA%\CPU-Z and rename the settings folder to add '.old'. This forces CPU-Z to create fresh settings — corrupted config files cause crashes.
4. 4 Run CPU-Z as Administrator. Right-click the shortcut → Properties → Compatibility → check 'Run as Administrator'. Some features of CPU-Z require elevated permissions.
5. 5 Check if CPU-Z conflicts with your antivirus. Temporarily disable real-time protection and test. Add CPU-Z installation folder to antivirus exclusions.
6. 6 Clear CPU-Z cache. Navigate to %LOCALAPPDATA%\CPU-Z\Cache and delete all files. Corrupted cache data causes rendering and processing errors.
7. 7 Repair CPU-Z installation. Windows Settings → Apps → CPU-Z → Modify → Repair. This replaces damaged program files while preserving your data.
8. 8 If CPU-Z still won't work: uninstall from Settings → Apps, restart, reinstall from official website. A clean install is the nuclear option but fixes almost everything.
