AIW 8500 makes vertical white lines on TV....

[Mawashi]

MY AIW 128MB displays vertical white lines going from right to left on my tv. I didn't have this problem with my Radeon 64MB so i don't think it's my TV. I'm using driver 6.14.10.64 @ 274/274 and MMC 8.1 on XP pro. Does someone knows how can i get rid of these white lines?

Update: The tech support guy at Frys told me that it most probably comes from a bad card and it needed to be replaced. Would greatly appreciate any imput on this before going through the pain of an exchange with ATI since it's more than 30 days that i bought it.
