also, what you remember happened right before this behavior started? Have you tried to install something, or uninstall, do System Restore, or major Windows update.
It is only my guess at this moment. What you see is dell Bios Splash screen. American something is American Trends, correct? It seems, preliminary at least, that your Windows installation got corrupted (MBR corrupted).
Are you the original owner of this laptop? If yes, did Dell sent you any DVDs with this laptop? Do you know if this laptop has a Recovery partition?
As jay32267 asked, do you see any F numbers to press on the bottom of the screen - if yes, which ones?
And you are communicating here by which means, spare PC/laptop (PC preferred) or smart phone?
