Judging by today's question, it's safe to say that you don't consistently monitor your CPU usage. Am I right? If you don't, it's not the end of the world, but it is a good idea to keep an eye on it every once in awhile. What do I mean by CPU usage? Well, it's basically the percentage of your computer system (programs, other applications, etc.) that's being used at any given time. Let's check it out!
If you use several programs on your computer at once, your usage may be a little higher than when you're not doing anything. Either way though, there is usually some part of your system that is filled up. Even when you're not using any programs, there will still be a small percentage gone due to the antivirus, firewall, spyware, etc. programs you have running in the background. It's nothing to worry about, but it's good to keep all of that in mind just in case.
To see how much of your CPU is being used at any given time, you just need to open the Task Manager. The easiest way to do that is to hit Ctrl + Alt + Del (all at the same time). It will then pop right up on your screen. Now, the percentage number is under the Processes tab and it's located toward the bottom, labeled CPU Usage. You can watch it fluctuate back and forth between the percentages if you want as well. That way, you know exactly how much is being used at all times.
While you're in the Task Manager, you can also look at some performance and networking numbers if you're interested in that. Again, it's always a good idea to keep your eye on these things, so go to it!
