Everytime i open an editing program (Windows Movie Maker, Adobe Premiere Pro 1.5, MovieShop, etc) the computer locks up completely. I can't ctrl+alt+del it cause everything is locked up. the only option i can do is hold down the power button until it is forced to shut off. In fact, it once froze when i was capturing video with my DV camera and it even froze my camera up. I just want a logical explanation and hopefully a way to solve. Is there something wrong with the graphics card, video card.....or wutever. If you guys cant me an answer tell me any good sites that might be able to give me an explanation for this. Thanks a bundle .
