I used to watch dvds on my laptop, starting about a week ago I haven't been able to do this anymore. about 15 minutes into a dvd playback gets really choppy. I don't know much about troubleshooting this sort of thing. I do know that my processor gradually climbs to 100%. I've tried closing down all my programs and unplugging all my usb connected devices, but it still peaks out. The only program I've installed recently is a video game, civilizations. I've uninstalled that to see if it would do anygood, it doesn't. The only suspicious thing I notice when I look at a list of running programs is about 5 instances of svchost running. I shut some down and my comp still plays choppy dvds and then I shut down the wrong one and my computer shuts down. Do you think this is a virus issue? I've run mcafee, spysweeper and spybot but my machine always comes back clean.
