Weird Happenings with LCD

[BuddyGuy]

Hey guys... new to this forum and Im already lookin for help.

My system was off. Turned on system, no signal on the LCD, computer not booting at all... it just turns on, and doesn't nothing because I can't hear it load anything, not even BIOS. The LCD is hooked up via DVI. Plug in the analog, everything works fine. System boots and all. Any ideas would be great.

LCD - 172T Samsung
Video - GF4 Ti4200
Mobo - P4C800-E

Thanks.

Maybe something in the mobo BIOS.

I don't think the mobo BIOS has anything to do with output selection.....

I tried using a DVI-DSUB converter and then plugging the analog into that and it works aswell.. But straight DVI-DVI, no dice.
