DON'T PANIC! At worst your computer is dead, but there's an extremely high chance that it can be easily fixed. On modern computers a part of BIOS is left after flash just for situations like this. You'll probably have to get a flash drive and copy some files to it and press some key combination after starting system. It should be able to pick up BIOS on flash drive and install it. On older systems, the procedure is same but uses floppy disks instead of flash drives. I don't know the exact information for Dell, but someone here must, so good luck. Hopefully someone will soon post exact answer. –  AndrejaKo Aug 3 '10 at 22:25

If it's under warranty, you should really send it back. If it's not... Then we'll try to go from there.
