I have just got a new computer (it has windows XP). Set it all up, and it works fine but whenever i try and play a video file (tried in three different programs) it either plays the video upside down or is extremly jumpy. I've downloaded the same codecs that I had on my previous systems and the video files play perfectly on that one. So i just dont understand what the problem is. I thought it my be the drivers, but I've installed them, but it hasn't changed. Also the web pages scroll really weirdly, like its reloading the page every time you scroll down. Any advice or help would be greatly appreciated. thanks.
