Hi i got this macbook pro last year in the beginning of august it was the newset one out... Heres the problem.. ok: i had an issue from last week when my mac would not turn on.. it would just turn on and beep once forever until i shut it down manually... so i went to the apple store and they did some tests and replaced the logic bord... so i brought my laptop home yesterday.. ever since i got it.. it has been running super slow. it took long to start up, and becuz of the speed i wiped my hard drive and also reinstalled the os x.... the cd's that came with my mac. Its still slow, it has imporoved a little but if i use skype and just the net it just runs slow!! i have gone to another place and used the intene.t. but its still slow.. When i try to use skype and watch youtube it slows down alot! then it takes a long time to start programs..and my mouse slows down also.. I have 231.4 bytes free of 249.72 Also i dont have any start up programs running right now... either i dont understand whats going on.. this never occured before..
