Keyboard won't identify, can't get into BIOS

[signature16]

For some reason my computer won't let me get into BIOS setup.

I've unplugged my harddrive. The monitor and keyboard are plugged in. When the computer booots it shows the processor and memory info and provide the option to press DEL to enter SETUP. I can not enter setup. I've tried multiple keyboards, multiple USB ports, but nothing.

Any suggestions?

In your computer specs "Dell XPS of some sort" is not an adequate description to help you solve your problem. Post the exact model of your Dell XPS machine.
