my cpu freezes when I'm browsing. It makes a repetitive whrilling noise much like that of a helicopter when it freezes. This ONLY happens when i'm surfing and not when I'm playing games, or running other programs. The freezing situation happens with IE8, then i started to use firefox, fine for a while but then, it starts happening with firefox as well.
my system specs:
acer aspire t1800 with 1g of ram. (the 1gig of ram works just fine and I don't think that that's the problem) an anthom 64bit processor, and my drivers are updated.
