Is there a chance that my Safari and iTunes crashes are related to the video card? I switched out my RAM and it seemed to reduce the problem for a while, but now it is back. Safari crashed frequently when I visit facebook, and iTunes crashes when I try and access the store. This seems to happen in waves, i.e. sometimes it will be fine for several days, and sometimes it will occur several times in a row and I simply can't use these programs. Here is the error log, is there any indication?
