I just got a Z87 Extreme4 motherboard to replace my Z87 PRO3. I got windows working and got to desktop. I deleted my z87 pro3 icon on my desktop (not sure what it was for) and my computer shut down. I tried to turn it back on, but it powers on to a black screen, occasionally the Asrock logo comes up offering to go into uefi or other things, but then the computer shuts down no matter what. When I try to go into the boot menu, it sometimes works. Other times the computer shuts down. When I get to the boot menu, it's just a black screen. When I move my mouse around, square inch pieces of the background pop up. About twenty seconds later, the menu completely opens instead of just small bits. It works for about 3-8 seconds, that crashes. I managed to get to the windows login screen once after getting into the uefi setup menu and booting up, but just before the desktop loaded, the computer shut down. I have no idea what's going on, and I'm incredibly frustrated.
