it is most likley
a virus right click on taskbar
and enter task manager and see what
the cause is.
Either there is a virus in your computer but your antivirus software just can't detect it or the memory manager is running in the background.
If your CPU usage is at 80%, you are probably trying to run too many programs at once. Try closing some programs, especially any that are processor-intensive (games, photo/video processing, etc).
No, everything does not cause everything. For example, your bath will not result in me eating a sandwich; usage of my television won't result in your car running out of fuel.
With modern processors all that should happen is that they will automatically slow themselves down (though the usage will still show as 100%) to prevent the danger of overheating. In theory, at least, running at 100% usage should not be harmful to the processor.
It depends on how many programs you run and how many programs ur operating system runs in the background. It also has to do with what processor you run and what operating system you use. On an average if you have any processor of Pentium 4 and up with a bare windows xp installation your CPU usage when the computer is idle it shoudnt be more than 8-10%.
About 90 to 98 percent.
Mandatory, before the first usage.
The memory usage might be high because you have a lot of programs or tasks running in the background of your PC. To fix this right click your task bar and hit "Task Manager". From there go to "Performance" and see what is draining your memory. You will be able to end whatever program it might be from there.
Google Chrome generally uses high amount of CPU. It is generally due to the various processes it keeps running.
No
PS would be the simplest and fastest way. top will display processes, along with memory and CPU usage, so it is more useful in identifying runaway programs.
Running the air conditioner, my electrical usage went up.Gasoline usage declines when cost rises too high.Old home phones billed for all long distance usage.
