Monitor stops display anything after unexpected power cord unplugged

[LeeZg]

No display at all while rebooting vista though everything on the tower seems to be normal (fans, beep, light on power and hard disk). It happened after power cord was unexpected unplugged. The LCD monitor works on other computers. Motherbd seems to be working fine(continuous beep when raw unplugged). Can't do anything when the system is "blind". Please help!
