I got an Ati Mobility Radeon x1400 When I try to make the direct 3d test with dxdiag The first one works fine but in the other two the rotating cube isn't complete. It worked just fine till now with the drivers I got when I bought the laptop and I haven't installed anything strange in the past week. I tried getting the latest drivers but some sort of error occured that said those drivers can not be installed on my sistem. I got those drivers from ati's site following the steps so I'm pretty sure I go the right one. I attached a dxdiag save.
