I got this computer freshly built from best buy today. I got the window's updates and tried to update my AMD Radeon 5700 XT, but the installation took a long time and then the screen turned black. I waited for upwards of an hour, but it never turned back on. I had to force shut off the computer and turn it back on. When it turned back on the computer was still on the old drivers. what do i do to fix this ?
