Dell Vostro flashing splash screen

Hi,

I am in deep kimchee as I have to do a radio show tonight and everything is in my computer. I really need help!

The splash screen with the DELL logo keeps blinking with F2 setup and F12 Boot Options displayed in the upper right corner. I removed all USB devices and am down to just the power cord in the computer.

I tried rebooting but that didn't do anything. In fact, it returned to that display so quickly I don't think I actually turned if off despite holding the OFF button for 30 seconds. It just seemed to go black and get quiet but pushing the button again and it almost instantly returned to flashing splash screen.

F2 and FN F2 do nothing

F12 does nothing

FN F12 causes the screen to stop flashing and you can see that display but nothing happens other than it stop flashing. Its been sitting there like that for about 20 minutes.

I read somewhere about someone who had this problem and solved it by pressing F2 and doing something on a menu. Pressing F2 does nothing for me; I don't ever get to a menu.

I don't know what to do!
