i3 3.06 GHz, 16 GB 1333 MHz DDR3, 500 GB HD, 256 MB VRAM I keep getting beach balls nonstop when doing anything. For example surfing the web with Firefox and only 4 tabs visiting sites that are mostly text based..i.e. no video or flash gaming etc. My hard drive is constantly making noise like it is writing something. What is going on? Forgot to mention that my HD is about half filled. Any suggestions?
