[seek you!]

The following is the troulbe that bore me for
a long time.
In the last month, my computer with XP OS. could not
work normally(it work very very slowly) when i were
applying the MediaPlayer or Winamp3 at the same time
opening a Internet Explore(just 'one'. ). But if i just
use WMP(or just winamp3) without IE excuting ,it works
normally. I have checked the tasm manager and found that
the IE. process almost consumed 50%~60% of CPU time, and
the MediaPlayer nearly consumed 20%~25% of CPU time, and
the task manager itself consumed almost 10%~15% of CPU
time, and the others of CPU time were consumed by the
system process. I have used many the latest antivirus-
software to check my computer but nothing found. And I
even have reinstalled the XP OS. but the problem exiting
still.By the way , my CPU is 1.70 GHz, memory is 256
DDR.
And I have tried all kinds of method I can to resue it
but furitless ,so the only way is to consult MS experts.
I am so so boring now!!! If you can help me to solve this
trouble, i would be grateful!!
Thank you for your help before you help!!!
