    My HD4850 won't run directx10

    Hi I recently purchased a Powercolour HD4850 512mb...via ebay. It installed fine with the latest drivers and the card itself seemed in good condition (the seller had a great feedback % too), however whenever I try and run a game in directx10 it morphs the screen into a mess of geometric lines. Sometimes I can see a bit of the image but even then it's usually been stretched at a weird angle. It runs directx9 perfectly. At first I thought it was just farcry 2 as I read it has had problems with this card and dx10, however I'm getting identical problems with Crysis, Fallout 3, Assassin's creed and even Sins of a Solar Empire (which used to run fine with my x1300/1550 series card!). It runs Spore but the graphics look like crap, like integrated graphics crap (which my motherboard doesn't have).

    I've also noticed that in dx10 it bluish blotches appear on the screen.

    I'm desperately looking for help, is this a hardware problem? What can I do about this? Has anyone else experienced this?

    I have all the latest drivers installed

    I tried taking a screenshot to show you guys the problem but it just took a shot of the window behind the program (in this case adobe illustrator).

    Sorry to hear that your having issues but I would imagine that if the card is running fine with Dx9 then its more likely to be some sort of driver issue. Are you certain that you uninstalled all of the drivers from your old card and did a driver sweep before installing the ones for your new card. Also did Dx10 work ok for you with your old card if it supported Dx10?
