Nvidia Fx 5700 LE

[BarB Wire]

Hi guys (first post), okay straight to the problem. My graphics card works great no crashes......no major problems, but there is one annoying thing about my gpu. The outlines of characters are not lined up perfectly so the outlines look like stairs. In any game the outline of characters, area ,vehicles, etc look like stairs. How do i fix this problem I updated my card from nvidia. Chaintech made my card i sent them an email and thier reply gave me a couple of options. One is turning FAST WRITE off in the BIOS. I have a compaq so i used f10 to acess my bios but i cant find anything about fast write WHERE IS THIS FAST WIRTE?!?!?!?!. PLEASE help me out on this.
