When your pc freezes are you on the internet? If so you might have spyware. Go to Google and serach for SpyBot serach and destroy it is free.
I got a new computer last October. It has been running fine up to now. It still runs rather well, but lately it seems to freeze when i am not on it. For example, today I got up and went to kitchen, not 10 minutes had passed. When I came back, the computer had frozen. Also this morning, I went to breakfast with my friends, came back and the computer was frozen. This afternoon, when I cam home the computer was frozen again. I thought that it mightjust be doign it every ten minutes or so, but I played Rome: Total War for an hour and nothing happened. So I am not sure what it going on. Any and all help will be appreciated.
