I got a laptop 2 days ago and it was working fine until today when I turned it on and went on Google Chrome. After about 5 minutes my computer screen went blue and it said "Your PC has encountered a problem- please wait while the computer restarts" and it has done this about 6 or 7 times though not in a row- I tried using internet explorer but it happened with that too though it seems to occur more frequently with Google Chrome. Also it is slower than it used to be but I don't think I have a virus already plus my stepdad installed Norton on my laptop! It is brand new and my parents will kill me if I ruin it! Please help!
