First, wait a moment. Check through every external connector, power cables, monitor cable, keyboard, and mouse. Make sure the monitor is switched on and it is working. Unresponsiveness may be due to loose connections or peripheral issues.
Press Ctrl+Alt+Delete. Open Task Manager, in case of responsiveness. Find applications that are labelled as not responsive. Right click on the non-responsive application and select End Task. This shuts down the faulty software.
Ctrl+Alt+Delete fails to start up, forcing a shut down. Place your physical power button in a pressing position and hold it down to 5- 10 seconds until the computer switches off. Wait 30 seconds. Restart by simply pressing the power button once.
A vital system check should be conducted once the system has restarted. Use your security program to scan thoroughly to have all the viruses and malware detected. Install those operating system updates that are pending. Keep an eye on Task Manager to check unusual CPU utilisation, or memory/disk use.
In case freezing continues, reboot into Safe Mode. Safe Mode loads only minimum drivers and software. In case the computer works fine using Safe Mode, then the problem is probably caused by a new installation of software, software update, or driver conflict. Drop new applications or reload troublesome drivers.
Conclusion:
Troubleshooting should start with verification of physical connections and waiting. To stop the unresponsive tasks use Ctrl+Alt+Delete and select Task Manager to end the process. Shut down forcefully, only when necessary. Restart and then scan your computer and update. Safe Mode can be used to trace and eliminate conflicting software or drivers on Arc Iris ongoing problems.
