Possible reasons for high GPU usage on desktop:

1. Mining software:
   • Check if any mining software is installed on your computer.
   • Look for any suspicious processes running in the background.
   • Monitor your system for any unusual network activity.
2. Resource-intensive applications:
   • Check if you have any resource-intensive applications running, such as video editing software or 3D rendering programs.
   • These applications can cause temporary spikes in GPU usage.
3. Multiple open tabs or applications:
   • Having multiple tabs or applications open simultaneously can increase GPU usage.
   • Close unnecessary tabs and applications to reduce the load on your GPU.
4. Background processes:
   • Some background processes, like Windows updates or antivirus scans, can temporarily increase GPU usage.
   • Monitor your system's task manager to identify any resource-hungry processes.
5. Malware or viruses:
   • Malware or viruses can use your GPU for mining without your knowledge.
   • Run a thorough scan with reliable antivirus software to detect and remove any potential threats.
6. Driver issues:
   • Outdated or faulty GPU drivers can cause abnormal GPU usage.
   • Update your GPU drivers to the latest version from the manufacturer's website.
7. Hardware issues:
   • In rare cases, hardware issues like overheating or faulty components can cause high GPU usage.
   • Monitor your GPU's temperature and check for any physical damage.

To determine if the high GPU usage is due to mining or normal activities, consider the following steps:

1. Check for mining software or suspicious processes.
2. Analyze the GPU usage patterns: if it consistently reaches 100% and drops, it could indicate mining activity.
3. Monitor network activity for any unusual connections.
4. Review your recent activities and installed programs for any potential causes.
