do u think i should try resetting the SMC, first and then try this, as snaky suggested?an
i was thinking about new os, would u reccomend going higher than 10.5.8?
Thanks, there it is![]()
Yours can run OS X up to 10.7.4, 10.7 isn't that good and seems buggy, you might try 10.6.8 though.
Before I told you to try to install OS X on an external USB stick, if I were you I would still try to do this or on an external HD.
Did you already try to reset the SMC?
As others have said it is probably your Graphic card, but I would at least try to run a clean OS from an external source.
