whenever i turn on my computer (everytime i turn it on) my cpu usage soars up and stays that way for about 2 minutes. its like my computer is straining to open all of the necessary starting programs. and also whenever i open limewire or winamp or any other program my cpu usage soars up for quite awhile. my computer has 512 ram so i didnt think i needed to upgrade because that should be good enough for normal usage. i would say the only thing that i do that would even take up that much, if any, cpu is downloading music or winamp. i know its not a virus because i have ran hijackthis and i have mcafee so im sure its not a virus. does anyone know whats wrong. its also really annoying because whenever i pull up winamp my music would stutter alot until the cpu usage went back down to/around 0%, which takes about a minute or two.
