Yea, that really doesn't help when I already stated everything I do is normal.
I did state that my machine has no kind of 3rd party software that runs when this happens.
I don't tweak my computer ( modifying it, etc )
I keep everything simple to the way it was ( so simple that I even use the Aqua wallpaper & Flurry screensaver lol )
I did run Disk Utility and tend to atleast once a month just to check if things are running ok.
So again, all is normal with what I run and throughout the time before this happens, everything runs smoothly with no hiccups.
