Dvi to HDMI Cable issues HELP ME :'(

I am having an issue with my monitor.

I use a dvi to hdmi cable from my radeon 7770 to my 19 inch monitor. (monitor has component, vga, and hdmi inputs)

At the top of my monitor i get a line of messed up pixels (about 1mm wide) all the way across the top of the screen. The odd part is this...
If i unplug and and reconnect my hdmi, it goes away.
And if my computer goes to sleep (and sometimes when i reboot) this line of messed up pixels shows up again.

This is most likely not my graphics card. Its brand new and runs my games at a nice frame rate.

Can anyone help me out? Has anyone had this problem at all?

(i joined toms hardware just to ask. lol it really bothers me)
