Your task manager shows a constant CPU usage of 50%, and your image shows no response. Let's diagnose this issue step by step.
Check Process Using Task Manager
Press Ctrl + Shift + Esc to open the Task Manager. Look for the process that is consuming the most CPU resources. Right-click on it and select End Task to terminate the process. If you're unsure about terminating a process, do a quick Google search to determine if it's safe to terminate.
Identify Idle Time
Check the idle time of your system by looking at the "Idle" column in the Task Manager. If the idle time is only 3% or less, it's a sign that your system is under heavy load. The ideal idle time is around 20-30%.
Diagnose
If the issue persists, it might be due to a software problem or a hardware issue. Let's try to diagnose it further.
Software Issue
Run a full system scan using your antivirus software to check for any malware infections. Disable any unnecessary startup programs that might be consuming resources. Check for any pending Windows updates and install them.
Hardware Issue
Check if your CPU temperature is high. If it is, your system might be throttling the CPU to prevent damage. Make sure your computer is well-ventilated, and consider using a cooling pad. If the temperature is normal, check if your RAM is running at the correct speed. A mismatch in RAM speeds can cause instability and high CPU usage.
Additional Troubleshooting Steps
Try resetting your Windows power settings to the default values. Disable any unnecessary services and background applications. Check if your graphics card drivers are up-to-date. If none of the above steps work, consider performing a clean boot to diagnose if any third-party software is causing the issue.
