I seem to be having a lot of problems lately goin on with my computer. Annoyingly of which is that I have to cmd+opt+esc force quit Firefox twice whenever I restart/turn on my computer. After the computer turns on and startup is all done, I try to open FF, takes a couple minutes, loads extremely slowly. Force quit once, a tiny bit better. Force quit twice, and it's like it never happened. Pages seem to take longer to load. Videos no longer play smoothly fullscreen, no matter the resolution (some times this isn't an issue though). And startup is a crap shoot, it's either slow or really fast. The fact that all this is random (slow one day, fine the next) just confuses me. And I'm absolutely no tech person, so is there something I can do? I've got 3gb RAM and 300gb of harddrive still available, with most of my media on an external. Granted my iMac is an 08, but I feel like my performance shouldn't be suffering like this.
