My computer started making a horrendous racket last night and I was a little surprised it was still functional this morning. I unplugged everything, opened her up, blew the dust out and plugged her back in with the case open so I could track the source of the noise. It was the case fan, an easy fix with a quick trip to the computer store for a new unit. I guess it's been on its last legs for awhile now, my box is much quieter with the new fan installed. Yeah, a cheap fix. :)
