Blue screen of death
has happened ONCE on this laptop that i am on now, happened when i was being hacked that second and hacker was controlling my mouse, cd drive everything and typing hahahaha ove rmy pc, so i basically pulled the plug
start ur norton, if it wont let u start the norton that means that u have a virus fur sure . . the safest thing you can ever do is pull the plug and wait until you know exactly what to do . .
