Hello, all. A few weeks ago, my computer died; one day it just would not turn on. I brought it to a local repair shop; it's a guy who does pretty good work at reasonable prices. After he checks it out, he said the motherboard, and a few other things were gone, and he could give me one of the units he makes in his shop, for a decent price, and that it would perform like new, and it has, except for one thing: the video player he installed, VLC Media Player crashes if I try to watch a movie. This is what happens: 1.) I load the DVD in the drawer. 2.) It shows me the main page. 3.) I start playing the movie, and then after 5 to 18 minutes, the video freezes, but the sound continues on for a few moments. Then it crashes, and the computer reboots. Does anyone have any suggestions as to what's going on, and what I can do to try and fix this without bringing the unit back to the shop? Also, the screen saver is crashing the same way after a few moments. Does the screen saver run off the media player as well? Any ideas and suggestions are appreciated. Mike P.S. Videos at youtube and other sites are playing fine.
