Driver Update For Smartdisk Ml-dazzle Dm-24001 Where Can I Find An Appropriate Driver To Update My Computer For Gaming?

Where can I find an appropriate Driver to update my computer for gaming? - driver update for smartdisk ml-dazzle dm-24001

When I run City of Heroes or World of Warcraft, I get error messages such as: GL_ARB_multitexture, GL_ARB_texture_compression, GL_EXT_compiled_vertex_array. Anyway, I went to the Dell website to get a good update ATI drivers for my Dell Dimension 4400, but the driver stops and gives me this error: 0x80040703. I have no idea what to do if someone can help, please, I appreciate it soo much!
