I use Corel VideoStudio Pro X3 video editing program on this Windows 7 Samsung laptop. I've enjoyed the program to edit video clips and haven't had any problems - until now. Once I edit a clip, I convert it from a VSD (I believe) file to something Youtube can read, like MPEG-4 (HD). It begins rendering, and once it gets to about 5% my computer inexplicably shuts down. It's done it three times in a row now. I can't even use this expensive program if I can't convert the file. Am I doing something wrong or is it a Windows 7 thing?
