Video playback help!
 

I know that I'm at the wrong place to ask this, but it's desperate!!

I've just recently updated by graphics (NVIDIA Quadro NVS 290), and since then, I've been having problems with video playback. On Winamp (my default media player), every time I try to load a video, it doesn't load. But when it does, and I press the stop button, Winamp freezes, and I can only close it down with the task manager. I'm worried that I may have to use Windows Media Player if I want to view videos now. Is it because of the update I did to my graphics, and if so, is there a way to revert it back to its original version?

Again, I know it's the wrong place to ask, but I really need this problem solved! :(

Uh.. okay, you can disregard this thread. It turned out that the new version of Winamp I had didn't display the videos. So, I uninstalled it and reinstalled the old version of Winamp I had before, and now it plays videos great. But in the process, I've uninstalled software for my graphics. :( It's times like this I wish I knew what I was doing.
