My problem is my computer keels freezing randomly... I have taken some of the start up programs off and uninstalled some things and it still freezes up. I opened it up and noticed there was a lot of dust. Would cleaning the dust out help? Or would it not? Running multiple programs does not make it freeze right away! But when I get on the internet and do something... ...after about 5 minutes it will come up with "not responding" and then I close it. Then if I try to open it up again it freezes the computer. If I wait it will freeze randomly! What should or can I do? By the way I used my Ipod touch to do this so if there are any spelling mistakes I am sorry.
