*Specs* XP SP3 SD37P2 E6600 2GB Dual DDR2 ATI HD 3650 Catalyst 8.6 I don't really know where to begin. This problem has been going on for a while now. I've tried all the obvious things, and am now working with a fresh install of *Windows XP SP3*. I first noticed something was up when I installed my new graphics card (*Passive HD 3650 by Club 3D*). Whenever I watched a video file whether on my hard drive or streaming (youtube, iplayer etc) I got strange horizontal lines all over the screen. After a bit of research I discovered a lot of information about solving this kind of issue, but everything I read gave the same answer - Turn on wait for V-Sync in *ATI Catalyst Control*. Some also recommended tripple-buffering. I have tried various combinations of these settings with the last 3 versions of the ATI driver (8.4 .5 and .6) This didn't help my problem at all. In the end I managed to solve the issue by using the EVR renderer in *Media Player Classic Home Cinema*. With the default options there was still a lot of tearing, but by enabling Lock Back-Buffer there was no tearing at all. Obviously, this didn't help my tearing issues in other applications. Particularly annoying is the tearing when browsing in *Firefox* and *Internet Explorer*. Scrolling pages is very unpleasant experience on my *HP w2207h 22"* monitor. I have also tried with a different monitor and a different cable (VGA rather than DVI/HDMI) and i have the same issues. How can i tell if I have a faulty card? Should I be expecting this with a mid-range card like the 3650? The family PC doesn't have this issue and it has a much older graphics card. Here are a couple of examples of what causes tearing. http://www.csseleven.com/ is really bad when scrolling and just about every single *youtube * video has horizontal lines throughout playback.
