i have a problem with my computer where the harddrive play AVI in a jerky frame rates. It used to play fast but now, it gets jerky. Before I remove the harddrive, it play fine, now I noticed the busy red light doesn\'t flashes anymore. I check the motherboard and the pins are properly connected. So, after I remove my hard-drive and made a temporary switch, the computer started to act a little weird, by that i mean slow. I have like 3 fans on my computer, one on top, one on side, and one on front next to the hard-drive.
