VGA cable screwing up my screen

My graphic card crashed, so I purchased a new one which unfortunately only has 1 DVI outlet(I have 2 monitors)(And the clerk insured me that it had 2 DVI outlets, I’m at birdie, a pretty big demo lan so I needed a new graphic card fast). So I had to use the VGA one. And it messes up the monitor :/.

Heres a pretty accurate illustration of what it looks like:

And heres the screen I’m using: http://www.webhallen.com/prod.php?id=74393
