Ok reciently i've been experiencing lagging a lot it' snot too serious but it stops for a tad and keeps going and when you watch videos on youtube or watch videos just in general it bugs me a lot. It also tends to happen when I type it just freezes for a sec. I've tried using Onyx to clear up everything, I try using disk utility for permissions, i've cleared my cookies and cache on firefox (and pretty much all my other programs) and even if I quit all my other programs except for one it still happens. All this helps it a tad but it doesn't seem to fix it. What could be making this happen and how can I make it better?
