Vertical Lines Display - Recovery shows set...

I have a Qosmio G35-AV650. It has vertical lines on the display. It recently had a video chip replaced about two months ago (I found that out after I bought it used, was told it was barely used and did not have any problems).

Anyway, it started with the vertical lines on the screen and was told to try recovering the system with the recovery disks. They would load in and seemed to be recovering all the way until it reboots, then comes up with a black screen. Going into safe mode shows that setup was not complete, run setup again.

I tried loading XP Pro with the Toshiba raid drivers slipstreamed into it, and I can get it to load fully this time but still has bad vertical lines in the display. If I try updating the drivers from Toshiba with the nvidea GeForce 7600 drivers, the screen comes up black when booting into Windows normally. I have to go back to safe mode and uninstall the nvidea to get the screen to come up again when loading Windows normally....still bad display though.

I tried again to use the recovery disks so I can get all drivers in there for wi-fi, etc., but it will not load...same thing, black screen when loading normally and then saying setup not complete in safe mode.
