Have you cleaned out your PC recently?
Please read http://forums.cnet.com/7723-6122_102-569818/getting-ready-to/?tag=contentBody;threadListing for ideas.
My computer makes a clicking sound and then freezes shortly after. This happened a couple of weeks ago too but after some time to rest, it resumed normal activity. However, the clicking and freezing incident has come back and has not resolved after a period of rest.
Please can someone tell me what is wrong.
