    Hi,

    I've been running Windows Vista Home Premium on my laptop since getting it new a couple of months back and everything's been fine and smooth. However, today everything's been running really slowly with the Aero scheme on - the window animations have been really slow. Turning it off and everything runs fine. Back on and it's slow. I tried a system restore and everything is fine on initial boot-up but then the screen flashes and it's back to running slowly almost immediately. Here's the weird thing - if I open a video in media player then everything goes back to running smoothly so long as media player is playing the video or has it paused - the window animations in Aero are back to running super smooth. The moment I close media player it's back to going slow.

    I've gone through Hijackthis and found nothing to worry about (also the system has McAfee and hasn't picked anything out). I think it was caused by an installation of Civilization IV which asked about installing DirectX 9 but presumably it wouldn't have overwritten any DirectX 10 files?! Dxdiag shows no errors and says it's still running DirextX 10.

    Has anybody got any ideas? Thanks in advance (y)

    Try uninstalling and re-installing your graphics adapter.

    I uninstalled ATI catalyst then did a driver rollback in preparation for reinstalling the driver and everything worked fine after the rollback so I'll leave it there. Won't bother reinstalling CivIV or anything else that comes with Direct X 9.

    Thanks (y)

    Sounds like an idea, at least until you want a game that needs DX9. DX10 is not a replacement for DX9 and is an incomplete version only for Vista. Many apps still require the DX9 runtimes.

    To resolve this, go to the Microsoft DX9 website, download the web installer, and it will in turn download only those parts of DX9 that are needed for runtime. Games should then detect the needed DX9 files and not attempt to install the full version.

    DX9 download here:
