Happy new year to all!

Windows XP pro sp2 with all MS update.I am using AVG free.Firefox for my browser.My problem is that my cpu seems to always be running at 50%.If i listen to music with Windows media player 11, Itune or Winamp, it keeps playing in slow motion and sound is shoppy.Also when i only surf the web,my curser keeps lagging.My mouse and keyboard is Microsoft wireless laser 6000.new batery.I had a power supply 400W before.(cheap)I had a 230W better quality that i have just install and it is just has bad.I tried installing a pci soundcard since mine is onboard.I returned it since my computer would not detected it at all.(keep in mind that i had purchased a no name brand for 20$ can)Also my cpu temperature seems fine.(below 50 degrees. Any ideas on my problem? I think it could be the cpu, but could it be that my power supply is not strong enough?If not with all the device installed on my computer,how strong should it be?Any model you recommend? Thanks in advanced!
