I have an Ultra 24 with Windows XP Pro installed and it has been working great for about two years. On Friday night I shut down the system and now it will not display to the monitor.
It has a Nvidia FX 3450 graphics card and will not display to the monitor at all during boot up. I don't even see the BIOS messages or the Sun splash screen before the O/S.
I removed the FX 3450 and installed a Nvidia FX 1700. Now I get some display, it shows the BIOS messages and the Sun splash screen. Then it starts to load Windows XP but I lose the display right before the XP logon screen.
