Hi everyone one, here is my problem :

I have a 15" macbook I bought in september 2011. Right away, I swapped in 8 gig of 3rd party RAM (since then I lost the original ram unfortunatly). It worked well until a few months ago it started to act weird : very long boot up time (up to 5/10 min before the loggin screen), then maybe another 5 min before the mac is usable. Movies under vlc started to freeze quite often for a few seconds (maybe every 10 min), safari too would start to freeze.

The patern is strange : the mac will be very slow to boot up, with many freezes for sometimes 20 minutes. Then sometimes it would be usable, sometimes it would continu to freeze every 30 secs for ever.
What I am calling freeze is not an actual freeze, it is the computer doing nothing but displaying th spinning mouse cursor. But I can still switch between applications, not use them thought.


What I tryed :

- rebooting like 304948487 times

- fixing permissions

- booting up in single user mode and doing several passes of memtest

- re-installing the OS ( I had no choice but to use the internet install, took days do DL, and got stuck in the install process, had to reset the PRAM)

- reset the PRAM (or whatever it is named for intel mac) several times

- removed all 3rd party software by puting them in the trash can

- installed Onyx and ran every clean / fix / scan tools


So, RAM and HDD seem to be ok. I used to play some games under steam and when it finally launched they worked perfectly (civ5, FTL). Windows 7 on its bootcamp partition is being weird too ( I have to wait 10 min before I can use it, then it is working well). Since I ran all the tools from Onyx, it seems to be a little better. But I had time in the past where it went better then bad again.


Do you guys have any idea


Cheers !
