Dell computer crash message

[Dwilhelm]

Hello, my Dell Experion 1100 crashed last night and now has a message: Broadcom UNDI, PXE-2.1 (build 002) v1.8.4 XE--E61 Media test failure, check cable (Which is actually wireless right now), and PXE-M0F: Exiting Broadcom PXE ROM Operating system not found

Can you open the system to make sure the card is inserted and the internal cable is hooked up I believe its in the modem compartment on the bottom.
