I would check in the windows device manager and make sure there aren't any ! which would indicate a forgotten driver install. I would go through the MB installs again and make sure you didn't skip one.

i will do that thanks hopefully it will make things run faster , the reason is i had to many games and pictures and music on the pc and the memory was full so i burned them all to disk and reformatted the pc plus i think i had a malicius virus i think
