OK heres the thing. This is my OTHER computer which is not connected 2 the internet. It has no antivirus on it, and no anti spyware. My computer has ranodmly been pausing, and sometimes locks up! The screen goes crazy with random lines and pixels everywhere! I think its usually when im in Media player 11. I have been having problems with a hard drive i installed recently. Its only 10GB but i ran out of space on my 80GB and i needed it until i could get a bigger hard drive. When i disconnect the hard drive.. then reconnect it after a boot up. It usualy works fine again. Any idea what this problem is... PS i didnt format the hard drive after i got it from a friend and its installed as a slave!
