Can't Boot

I try to boot up my new beagleboard with the dvi monitor but it does
not show anything in the monitor. I have provided +5V with 2A input.
The keyboard and mouse seems to be powered with light on. The five
leds are lighten all up but the result, i can't see anything show up
in the lcd. Is there any problem with my board?
Please advise...


Anyone can help??

Are you seeing anything being printed out the serial port?
