i see nobody helped here, but i managed to solve this problem on my own.
playing with directx is not recommended. so forget eradictors and tools like that. before updating directx (xp with service pack 1 has directx 8.1) it's much better to install service pack 2 because direct3D will be automatically installed. if that doesn't work windows must he deleted and installed again then graphic card must be updated with proper dirver and then install service pack 2.
