MBP Penryn 2.4, Spinning Gear and Apple screen

[chapel321]

goes on 4ever!! Also, i keep getting the spinning beachball and can't do anything...force quit included...running 10.5.5 with all updates. Here's what I've done:
Replaced original Apple Ram thinking it may be bad( used 2 new Apple ram sticks and get same results)
smart checked out
permissions checked and fixed...still doing it
reset pram
erased and reinstalled Leopard..thought it was ok, then it started the beachball again after about 30 minutes of use, I was opening iTunes 8.0.2 when it hung up this this time and only surfing the other times. I have no idea what's wrong I guess it's Genius time. Any more suggestions are welcomed and appreciated.
Thanks

No, you don't understand...I replaced the original Apple ram with new Apple ram and it does the same exact thing, I doubt i have 2 pair of bad sticks.
