Hey guys, I'm having some trouble with my internet browsers I'll start up my computer and everything works fine but after about 20 minutes it stops working. My default browser is Firefox but I've tried using IE and Safari but they all stop working at the same time. I try and check for a problem by running a repair scan on my computer but it doesn't detect anything wrong. I have Windows Vista Home Premium on a Toshiba laptop if that helps in any way. Please respond! It's driving me crazy!
