Simple defrag + msconfig edit.
Unclick everything you do not use... this includes real time player, quicktime player, AIM, MSN... everything you do not use.
Type each line on the list on here if what you did doesn't help, i will try to help if i am still in front of the screen... or else you'll have to wait until tomorrow.
think its sorted....any other probs that occur i will let u know cheers
