Ok I'm having an Ecs 8800gtx, and im also having a problem with it. Its giving blue and green vertical lines over display.I've checked on other computer too, so the problem is with the graphic card. But when vista is running there are no jagged lines but the os doesnt let the device to run in device manager the problem is only before the os loads. My question is should I try to reflash the graphic card or send it for repair to the company? How to I reflash the grfx card plese give me steps I've downloaded the bin file from tech powerup for ecs8800gtx bios flash.
