why is my laptop so laggy suddenly then back to normal then again with the lag then over and over again?

i don't know when the first time it came like this. just realize, that it bothering me currently.
my laptop is so laggy every time it comes(i don't know what it is).
my cursor delaying (for about 3 seconds) to follow my move. then when it comes to become normal again, it rerun the windows explorer
how i suppose to fix it?
btw, sorry for my english

It'll do that if it gets hot. Blow it out and use a laptop cooler.

thanks for the answer..
it isn't hot.. my cpu at 41C and HDD 38C(know this by batterycare). it comes just sudden.. doesn't care when/how much i use it..
either light or heavy work..

41C isn't hot enough to cause problems, assuming the temperature reading is accurate.

And so the answer to his problem is ?

I've no idea. But recommending he buy a laptop cooling mat isn't an ideal first action, considering his temps shouldn't even be a problem.

Could you post up your system specs including Operating system?

Keep task manager open on the performance tab or an independent program that will monitor CPU (and RAM) usage. When you have a slow down check the usage at these times. If you are getting high usage spikes when you get these slowdowns it may be related to a background process. In which case it is a matter of identifying this process, killing it and preventing it from launching at startup.

If it is not caused by resource usage spikes it may either be a HDD issue or as mentioned related to temperatures. Although as you say this happens under light and heavy load I would be less inclined to believe it is a temp issue. You could download something like hwmonitor just to be sure though as your CPU has a 1ghz turbo boost that may be causing high temps. As for the HDD you could run a disk check or use a program that monitors disk usage to check usage when slowdowns occur.

checked and optimized my harddisk.. it's now doing well..
hopefully not turn laggy again..
thanks a lot for all of you.. really appreciate it..
