2900xt Horizontal Pixelated lines, Atikmdag, BSOD's, etc

[phantomstranger]

Hi guys and girls, i recently woke up one fine morning to find on boot up of my PC that i had Horizontal Lines running all over the place, a couple of minutes latter i receive a BSOD and something about atikmdag. uninstall drivers, change monitors, etc and it still has these pixilated lines and texture tearing problems. reinstall Vista and it fixes it as long as i don't run 3d aps or Movies. as soon as i do, the game has texture tearing, pixelated lines, the whole shebang. Any ideas? rolling back or installing new drivers don't work. please help, its driving me insane

Especially annoying when people put in the effort to reply.

Excuse me previous posters, but some of us have lives and 11 days is not a lot of time. Remember patience is a virtue . I have just finished a hectic week at university with back to back assignments and have only just received an email from toms's telling me that i have had replies. i also stated in the original post that i have installed AND rolled back drivers without success. Also i have never had an Nvidia card installed in the system . Please don't be so rude.
