[help] graphic problem !!!

i dont know how to post so i posted here and on the suggestion/request/help.


i just got a new graphic card to replace my gay asus N6200 256MB AGP 8x.

i have now EVGA e-GeForce 7600 GT superclocked 512MB DDR2 AGP 8x.
yeah this card own ass !!!!!!

but... the problem is :

with all game but ill take BF2 and BF2142 for exemple.

"C:\Program Files\EA GAMES\Battlefield 2\BF2.exe" +menu 1 +fullscreen 1
"C:\Program Files\EA GAMES\Battlefield 2\BF2.exe" +menu 1 +fullscreen 0

when i run game with "1" i see like a line going up
when i run game with "0" i dont have any problem

when i check video taked with fraps , i dont see the probleme ("1").
so i think the problem is my screen!

If u haven't noticed, the resolutions that don't work aren't in classical 4:3 ratio, some are 16:9, some 16:10 (my screen, 1690 x 1050), use those that have your ratio (probaly 4:3)
