I have bought a new PC and my available memory hovers just above/below 5GB out of the 8GB installed. Also, my disk usage is constantly showing as 99% or 100%.

I am not doing anything except browsing the internet when it is this high, which concerns me as I am due to use it for programming soon. So what can I do to free up space?

EDIT: noticing now that already that my memory is dropping below 50%. This surely isn't normal given that I am not doing anything?
 
Solution
You may not be doing anything but computer is. Just see what's using that extra memory. It's not unusual for windows to use 2 - 3GB of RAM just at idle.
