What to do if computer is running slow

Malware or Viruses

A virus or a malware program can cause a lot of problems in your PC. A slow computer is just one of them. If using your computer for work, use an anti-virus or a malware scanning program to make sure your computer is not infected with anything.

Windows has a built-in diagnostics tool called Performance Monitor. It can review your computer’s activity in real time or through your log file. You can use its reporting feature to determine what’s causing your PC to slow down. To access Resource and Performance Monitor, open Run and type PERFMON.
