I have no clue what happened but my laptop won't play videos anymore. It was working fine earlier today but I open up The Office tonight and everything was in grey. After exiting out and pressing play again, there was no video at all this time, only sound. I tried uninstalling all my codecs and restarting but its been to no avail, I still get just a blank screen. If anyone can help me out, I'd be very very grateful. I'm in college right now so tv is all I have!

Nvm, fixed it. After re-installing the codecs like five times, I went to the K-Lite website and found my problem. Somehow Vista fiddle with my video playback settings in Ntune, making the brightness almost non-existant and the colors completely de-saturated.
