I have a Tbird 900 working on an Asus A7V133 at 1 Giga (7.5 x 133) and I am having lots of problems with a Leaktek GeForce2 GTS 32 Mbts. This is a new card I bought in retail package, and it's giving me a lot of blue vertical lines and symetrical dots (one dot at the vertice of a chain of squares). Yesterday I sent a message to Leadtek and I hope to hear from them soon.
