My laptop had been open to the internet and iTunes for a while. When I went to type a new website in the screen completely froze. Task manager wouldn't work, so I powered off. When I turned it back on, it scanned a disk and said it was ok after a while. So my laptop restarted and it seemed fine, but when I went to the internet, after a minute it would freeze. Again, nothing worked, my mouse froze, task manager wouldn't come up so I was forced to shut down. When I restarted it scanned disks again, but the same thing keeps happening.
I have windows vista, and internet explorer 7
