Ok, something is wrong with my computer and I don't have the slightest idea of what it could be. I have virus protection so I don't have any idea of what it could be. The computer boots up just fine but none of my programs will open, and I can't connect to any networks. When I try to open the programs, nothing will happen or they will say not responding. This happens for every program. Can anyone here help me figure this out? It's Windows Vista.
