To check PC performance, you can follow these methods:
Use the Task Manager (Ctrl+Shift+Esc) to monitor CPU, memory, disk, and network usage.
Run benchmarking software like Geekbench or PassMark to assess your system's performance.
Utilize the Windows Performance Monitor (type "perfmon" in the Start menu) to view detailed performance statistics.
Check the Windows Experience Index (type "WinSAT" in the Start menu) for an overall performance rating.
