Hello. I've been using Windows 7 for some days now. I have this annoying problem...When I have installed the Ati driver and catalyst control panel everything works fine. But after like 1 or 2 days they stop working. In Windows Media Player for example....I have sound, but no picture. In Media Player Classic I only have a green screen when trying to watch movies in all kinds of formats (mvk, avi etc) The drivers start working again if I re-install them...but I don't want to do that forever...Anyone else experiencing the same problem? Is there a solution? I'm using an Sony Vaio Fw21e laptop. Running build 7057 (had this problem with previouc version to) Driver version: 220.127.116.11. Edit: When I have re-installed the drivers, I don't get any picture before going into Catalyst Controlpanel and to any menu there that shows video, like 3D options and Avivo Video. Its like the drivers activates when I go into the control panel and watch a configuration-sample in the control centre.
