I have a refurbished, out-of-warranty Gateway Profile 5 desktop. The screen is totally blank. I contacted Gateway. They are pretty confident the built-in display is defective. I was able to attach a second display which would also go blank just after the Windows XP Pro splash screen appeared. Using the 2nd display, I was able to access the bios. When I looked at the display setup, it was set to LCD & CRT. Not thinking, I changed the setting to LCD since I wasn't using a CRT. That disconnected my 2nd display, so I now have two totally blank screens. How can I re-access the 2nd display and then also avoid a blank screen when Windows XP boots up?
