Hello I am having a problem with my graphics card driver i have just built myself a computer and when i install the graphics card driver when it reboots and goes parts the windows start up vertical black line appear on my screen and shortly after that it goes to a black screen. The graphics card i am using is a xfx radeon 6850 I know its the graphics card because when i go onto safe mode and disable the graphics card drive I can go on normal mode without any problems. I have tried to install the driver from the disk, website and going into device manager and updating the driver which says that it is at the best update and the problem still accrues if you know how to solve it please help.
