You opened the case? You're going to have at least one heat sink on the CPU and that is going to be caked with dust. It's going to have it's own fan, mounted on a bunch of fins(the heat sink). If you have a graphics card there will probably be dust on on that.
One other thing, whenever I do this i always use a pencil or something else to stop the fans from spinning while blowing dust through them.
Before putting the case lid back together plug it in and check that all the fans are spinning. There is going to be at least two of them, one on the CPU and one on the case itself.
