I reinstalled my Windows 7 back around the end of august. I have all the updates including the service pack 1. Well, I like to film videos with my Go Pro Camera and Fraps. Anywho... here are my pc specs.

Quad core, 4 gigs ram, nvidia 460 gtx, w7 64 bit

So I know everything is fine because I used to make videos for years. But this is now the 2nd time this has happened and it happened last month.

The problem that im having is I can load a video, doesn't matter the format of the video. Itll load fine. But after I go to play the video on the movie maker, the screen is black but I can hear the sound. I thought maybe the codec got corrupted. So I downloaded K-lite codec package and thought maybe that would fix it. But nope.

I have no idea why it just randomly decided to do this. Does anybody know why or have a solution to fix it?
