Many Windows PC users experience lagging and delays due to a CPU operating at full capacity. This can be caused by resource-intensive applications, outdated drivers, background processes, or malware. Disabling the High Precision Event Timer in Device Manager can help reduce system resource demand and improve performance. Additionally, regularly updating drivers, disabling unnecessary background applications, and conducting malware scans can further optimize system performance. Maintaining a clean and updated environment is essential for preventing CPU overwork.
