yeah it matters, i run an audio editing software. when the cpu usage goes up and down like that the software hungs up but the music continues playing.
its wouldnt matter if as it does is jumping up and down but it slows the the computer and hang up application.
i doubt its a software issue because i reset the laptop to factory defaults but that didnt resolve the issue, so i reformat the machine and it still didnt solve the issue and the reason why i did it twice because its my first time restoring so the image that came with the laptop might be bad or the image has so much application it just eats up all the processes so i ran out of ideas i reformat the whole thing. but it didnt solve anything.
