9.12 driver causes bad pixel lines?

[xjmtx]

so i installed 9.12 drivers on my 5750 and got these strange multi colored lines across the higher portion of my screen and several sets of blue pixels that look sorta like || just randomly shambled along the bottom portion of the screen. when i uninstall the 9.12 driver and use the default pnp display style the lines go away. i installed the hotfix hoping that it would...fix this issue, alas it did not. also when i start the computer, the pixelation is not there until it actually boots into windows (not during post). so it's not a cable issue. it is only visible when the drivers actually start. i un/reinstalled the drivers 6 times redownloading the package three of those times to ensure it wasn't a corrupt download or install. (tried installing 9.11 as well same thing)

does anyone else have this strange issue when using a 5700 card on win 7? any strange horizontal lines that are multicolored (also only one pixel tall) or mulitple blue || marks scattered along the bottom?

so a business week has passed and i tried various other things on this problem to no avail. it seems that the horizontal lines across the top went away when i changed backgrounds which is odd because it was the win7 default background that had the lines, but the blue pixels show up in black. kinda like how to show the sheen in superman's hair they used blue....similar effect is happening here. i almost thought it was gone but then i saw the blue pixels in the steam icon. and when i create a selection box and move it over the steam icon, the pixels go away and don't reappear until i right click or do something else on the desktop. what the devil is going on here. if need be i'll post pictures of the trouble.
