My computer runs fine 99% of the time, but when I watch a movie or a video or something, the system goes insane. For instance, while watching a movie the Task Manager reports that explorer.exe starts using like 600+ Meg of RAM which is completely absurd. I was wondering if anyone had any ideas about what might be causing this. I would normally think that it is the player, but it isn't because it happens regardless of the player and it continues even after the player is closed, and it is reported as explorer.exe. Thank you very much.
