whenever i use ie or firefox, a lot of the time it keeps coming up with an error message saying there is a problem and the program needs to close.
but when it doesnt do that when i try to close the browser, it freezes so i then have to ctrl alt and delete to terminate the program as none responsive.
both browsers have been re-installed to see if that would help but it hasnt, we also have norton 360 which is not showing any viruses etc. i even wiped everything off the computer and started the system again from scratch but that hasnt helped either. its just becoming a big problem now. any ideas?

have you tried it without norton 360 installed .
