2009 iMac no prior damage, loading bar fills half way, then horizontal line flashes on top of screen and then reboots. Only boots in safe mode, so we think it is the video card?? Anyone have any other ideas??


It seems something related to heat, did you try changing the termal paste and cleaning the heat pipe, fans and check if they are good?
I would try with that first
