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.
What makes a computer slow?
Your storage drive and memory (RAM) are the two key pieces of hardware most related to the speed of your computer. With too little memory, you will only have limited resources to run multiple programs, while using a dated storage drive can slow down your computer even if it’s recently been defragmented.
