I have a Alienware 17 R3 laptop that has display problems. I recently replaced the motherboard and the display does not come on. Windows recognizes it but when booted it doesn't do anything no logo no BIOS no Windows.
I have connected an external display and that does work however. I cannot goto the BIOS and check anything because it will not show me the BIOS. It comes on just as Windows loads the login screen.
I've tried everything I can think of but it won't display BIOS.
