At times, my Zoom Player malfunctions. For instance, it won't play any video file [avi, divx, rmvb] at times. Otherwise, it plays them beautifully all the time. But sometimes, Zoom Player just doesn't play them, without showing any error msg. During those times, if i open the movie in VLC player, the playback is very flickery. And after around 2 mins of playback, computer restarts automatically. can someone tell me What's the issue here and how to fix it?
